Our History
Endocrinology at the University of Colorado School of Medicine
1959-Present
Whitney Goldner took the reins as Endocrinology Division Head and the Frederic C Hamilton Professor of Medicine on July 1, 2024. She had previously (2004-2024) been at the University of Nebraska Medical Center, where she was Professor of Medicine and Medical Director of the Thyroid and Endocrine Tumor Program.
Dr. Goldner attended Medical School at the University of Nebraska, did Internal Medicine Residency at the University of Utah Medical Center and completed Endocrinology Fellowship training at the University of Iowa (2003). Her clinical and research focus is in thyroid and endocrine neoplasms, specifically focusing on environmental risk factors for thyroid neoplasms. She served on the NCCN Thyroid Cancer and Adrenal Neuroendocrine Tumor Guidelines Panels for many years while at the University of Nebraska.
She is an active member of the Endocrine Society and has served on their Board of Directors and chaired multiple committees; she is currently serving as the Chair of the Clinical Advisory Core Committee. She has also been a prominent member of the American Thyroid Association (ATA). She is a member of the ATA Thyroid Cancer Guideline Committee. She co-chaired the ATA Annual Meeting in 2024 and the ATA Spring Meeting in 2020; she served as President of Women in Thyroidology, Chair of the Awards Committee and Chair of the Trainee Development Committee. She is also an active member of the International Thyroid Oncology Group.
Dr. Lauren Fishbein was appointed Associate Head for Research in December 2024 and Dr. Neda Rasouli was named Director of Clinical Trials (CUDECT). July 2025 brought more division leadership changes. Dr. McDermott stepped down as the Endocrinology Practice Director at University of Colorado Hospital, after 28 years in that role (since July 1997). On July 1, 2025, Dr Palak Choksi took over as the Endocrinology Practice Director and Dr. Amanda La Greca became the Director of Clinical Outreach and Specialty Services. On July 1, 2025, Dr. Katja Kiseljak-Vassiliades replaced Dr. David Saxon as Chief of the Endocrinology Clinic at the VA Medical Center. Dr. Helen Lawler continued to serve as Director of the Practice Quality and Safety Committee in the UCH Endocrinology Practice.
In 2024, Dr. Michael McDermott received the Lucas Family Endowed Chair in Endocrinology and Diabetes and Dr. Jane Reusch received the Amy Davis Endowed Chair in Diabetes and Women’s Health. This brought the number of endowed chairs in the Division to 5: Whitney Goldner (Frederic C Hamilton Endowed Chair in Endocrinology), Bryan Haugen (Mary Rossick Kern and Jerome H. Kern Endowed Chair in Endocrine Neoplasms), Boris Draznin (Celeste and Jack Grynberg Professor of Medicine), Michael McDermott and Jane Reusch.
Faculty recruited included Dr. Jennifer Morrison MD/PhD (September 2025) and Eileen Findlay PA (July 2025).
As of March 2025, the Endocrinology Division faculty consisted of 35 MD/DO’s, 3 MD/PhD’s, 19 APP’s, and 20 PhD’s. By rank there were 18 Professors, 20 Associate Professors, 18 Assistant Professors, 8 Senior Instructors, and 13 Instructors. By March 2025, 157 fellows had completed training in the CU Endocrinology Division and 11 were still in training.
Dr. Bryan R. Haugen was appointed Head of the Division of Endocrinology on August 1, 2007, and became the Mary Rossick Kern and Jerome H. Kern Chair in Endocrine Neoplasms Research. Dr. Haugen attended Mayo Medical School, receiving his MD in 1987. His Internal Medicine internship and residency were at the University of Colorado, 1987-1990. His Endocrinology Fellowship at the University of Colorado (1990-1993) was under the mentorship of Dr. E. Chester Ridgway.
His research and clinical expertise focuses on the causes and treatment of thyroid cancer. He is acknowledged nationally and internationally for his scientific contributions in this field. His insightful research has resulted in multiple research grants from the National Institutes of Health and the publication of numerous manuscripts in peer-reviewed medical and scientific literature, books and book chapters, and many invited national and international lectureships.
He was the lead author on the American Thyroid Association Clinical Practice Guidelines on the Management of Thyroid Cancer in 2016. Dr. Haugen was honored by being elected and serving with distinction as the President of the American Thyroid Association (ATA) in 2012-2013. He also received numerous prestigious awards, including the ATA Paul Starr Award and Lectureship (2012), the Endocrine Society Edwin B Astwood Award Lecture (2012), the ATA Sidney H. Ingbar Distinguished Lectureship Award (2019) and the Endocrine Society Outstanding Scholarly Physician Award (2022). Dr. Haugen stepped down as Division Head in July 2024 to focus on his research in thyroid cancer; he also became the Department of Medicine Director of Philanthropy in 2024.

Dr. Mark Bridenstine left to work for Kaiser Permanente in Honolulu, HI, in 2015 and returned to Denver in private practice in 2018. Dr. Joshua Klopper and Dr. Jennifer Morrison left to work for Kaiser Permanente in Denver, CO, in 2016; Dr. Klopper left Kaiser to work for Veracyte (molecular diagnostics) in 2021. Dr. Kathryn Horwitz retired in 2018 after a distinguished research career and receiving the Distinguished Professor rank in 2018. Teri Hernandez was promoted to Dean of Research in the CU School of Nursing in 2019.
Dr. Robert Eckel retired in 2019. Dr. Arthur Gutierrez-Hartman and Dr. Janice Kerr retired in 2020 and Dr. Margaret Eagan left to work for Virta Health in 2021. Dr. Jim Falko partly retired in June 2021 but continued part-time work in the Lipid Clinic in the UCH Cardiovascular Center (CVC) until he retired in 2025. Dr. Julia Rifkin also retired in 2025. Dr. David Saxon became Head of Endocrinology at the Denver VA Medical Center in July 2021 when Dr. Wierman, after a very distinguished career, stepped down from that position to continue her devoted research in pituitary physiology and disease. Dr. Katja Kiseljak-Vassiliades took over as Division Head at the VAMC in 2024 when Dr. Saxon became Director of the Peer Mentored Care Collaborative, Director of the Cardiometabolic and Lipid Clinic, and Director of the Lipid Apheresis Unit at UCH.
Dr. Marc Cornier left the University of Colorado in November 2021 to become the Director of the Endocrinology Division at the Medical University of South Carolina (MUSC) in November 2021. Dr. Troy Donahoo, a previous fellow in the Division (1994-1997), became the Director of the Endocrinology Division at the University of Florida in August 2022. Under the leadership of Dr. Saxon, Dr. Lawler and Dr. McDermott, the Endocrinology Practice created the innovative Diabetes Home and Remote Care (DHRC) Center in 2020 to make top quality diabetes care available virtually to all UCH patients and to people throughout all of Colorado.
During this time the Endocrinology Practice at University of Colorado Hospital continued to be recognized by US News and World Report as one of the top US hospitals for the management of diabetes and hormonal disorders; the Practice ranked #6 in the US in 2017 and 2018 and #10 in 2019. In addition to honors and leadership positions earned by Dr. Ridgway and Dr. Haugen (see above), Endocrinology Division members garnered numerous national awards from professional organizations: Endocrine Society Fred Conrad Koch Award (Dr. Kathryn Horwitz, 2010), Endocrine Society Sidney H Ingbar Distinguished Service Award (Dr. Margaret Wierman, 2009), Endocrine Society Distinguished Educator Award (Dr. Arthur Gutierrez-Hartman, 2009), Endocrine Society Distinguished Physician Award (Dr. Michael McDermott, 2013), ATA Woman of the Year (Dr. Virginia Sarapura, 2013), Endocrine Society Mentorship Award (Dr. Margaret Wierman, 2015; Dr. Jane Reusch, 2022), and Endocrine Society Outstanding Clinical Investigator Award (Dr. Robert Eckel, 2016). Faculty members also held significant leadership positions in national organizations: President of The American Diabetes Association (Dr. Jane Reusch, 2018-2019), President of The American Diabetes Association (Dr. Robert Eckel, 2019-2020), President of the International Society of Endocrinology (Dr. Margaret Wierman, 2020-2022), President of the American Thyroid Association (Dr. Bryan Haugen, 2012-2013) and President of the American Thyroid Association (Dr. Michael McDermott, 2023-2024).
In March 2020, Dr. Dan Bessesen stepped down as Chief of Endocrinology at Denver Health and Hospitals (DHH). Dr. Rocio Pereira then took over as DHH Chief of Endocrinology. In 2022, Dr. Pereira also became Director of Community Integrated Health Care at DHH.
Dr. E. Chester Ridgway was appointed Head of the Division of Endocrinology on July 1, 1985 and later became the Frederic Hamilton Professor of Medicine. Dr. Ridgway attended Medical School at the University of Colorado School of Medicine, receiving his MD in 1968. He then did his Internal Medicine internship and residency at the Massachusetts General Hospital. He subsequently did his Endocrinology Fellowship at the Massachusetts General Hospital and Harvard Medical School, where he trained under Dr Farah Maloof. He later became Director of the Thyroid Unit at Massachusetts General and a national and international leader in the field of thyroid gland disorders, including hypothyroidism, hyperthyroidism, thyroid nodules and thyroid cancer. His studies of the regulation of thyroid stimulating hormone (TSH) secretion to control the thyroid gland resulted in very significant advances in the understanding of thyroid physiology and thyroid disease. His dynamic research resulted in numerous research grants from the National Institutes of Health and the publication of over 200 manuscripts in peer-reviewed medical and scientific literature, over 50 books and book chapters, and numerous invited national and international lectureships.
Dr. Ridgway was honored by being elected and serving as President of the American Thyroid Association (1996-1997) and President of the Endocrine Society (2003-2004). Throughout his career, he received many prestigious awards, including the following: American Thyroid Association (ATA) Distinguished Service Award (1999), ATA Paul Starr Award and Lectureship (2003), ATA John B Stanbury Thyroid Pathophysiology Medal (2008), Endocrine Society Robert H Williams Distinguished Service Award (2009) and the ATA Lewis E Braverman Distinguished Lectureship Award (2011). At the University of Colorado, he received the Joseph Addison Sewall Award in 2003 and the University’s highest honor, Distinguished Professor of Medicine, in 2011.
Under Dr. Ridgway’s leadership, the Endocrinology Division expanded further and became much more diverse with the recruitment of additional physician scientists to the faculty, including Drs. Arthur Gutierrez-Hartman (1985), Margaret Wierman (1987), Dan Bessesen (1990), Virginia Sarapura (1990), Jane Reusch (1992), John Merenich (1992-1996; Practice Director), Bryan Haugen (1993), Cheryl Pickett (1994), Lisa Kosmiski (1995), Michael McDermott (Practice Director, 1997), William Troy Donahoo (1997), Holly (Thompson) Wyatt (1998), Marc Cornier (1999), Whitney Woodmansee (1999), Diana Dills (1999), Leigh (Kish) Perreault (2001), Linda Barbour (2002), Carol Zapalowski (2002), Cecilia Low Wang (2003), Warren Capell (2003), Katherine Weber (2004), Janice Kerr (2006), Victoria Catenacci (2006), Rocio Periera (2006), Micol Rothman (2006), Joshua Klopper (2006), Irene Schauer (2006), James Falko (2006) and Jennifer Janssen (2007), Paul MacLean (2001) and Advanced Practice Providers (APP) Erin Meyerhoff NP (2003) and Joanna Gibbs PA (2005).
Drs. Berhanu, Dills, Picket and Zapalowski eventually left the Division for pharmaceutical or medical device companies. Drs. Merenich, Donahoo, Weber and Klopper left CU to work at Kaiser Permanente in Denver and Dr. Janssen left to work at National Jewish Hospital in Denver. Dr. Donahoo later left Kaiser to become faculty member at the University of Florida. Dr Woodmansee briefly did research in the pharmaceutical industry and then successively became a faculty member successively at Harvard Medical School (Peter Bent Brigham Hospital), Mayo Clinic (Jacksonville), and later the University of Florida (2019). PhD faculty added to the Division during Dr. Ridgway’s tenure included Drs. William Wood and David Gordon, who made significant discoveries in the molecular biology of TSH subunit gene expression and regulation in the pituitary gland. The Ridgway research group also elucidated the precise cell cycle pathways associated with thyroid hormone control of thyrotrope cell growth.
Dr. Robert Eckel served as the President of the National Association for the Study of Obesity (NASO), 1995-1996, and was President, American Heart Association, 2005-2006. Dr. Eckel then became the Charles A. Boettcher Endowed Chair in Atherosclerosis. Dr. Kathryn Horwitz served as President of The Endocrine Society, 1998-1999. Dr. Horwitz was honored by being selected as a Distinguished Professor of Medicine in 2004. Dr. Jane Reusch was President of the American Federation for Clinical Research, 2002-2003.
Fitzsimons Army Medical Center was established in 1918 as Army General Hospital 21 and was renamed in 1920 after Lt. William T. Fitzsimons MD, the first US Army Officer to die in World War I. Numerous service members served with distinction at Fitzsimons until it closed in 1997. Endocrinologists from Fitzsimons and CU had close clinical and research collaborations during that time. In 2001, the University of Colorado Hospital moved to the Fitzsimons site, renamed the Anschutz Medical Campus. The CU Endocrinology and Diabetes Practice moved to the Anschutz Outpatient Pavilion in Aurora on April 16, 2001. The Division offices and research space moved to the Anschutz Campus in April 2003 and located in Research Building 1 South.
Dr. Ridgway stepped down as Division Head and became Senior Associate Dean for Academic Affairs for the University of Colorado School of Medicine in 2007, but he remained active in the Endocrinology Division. In the summer of 2014, Dr. Ridgway was diagnosed with pancreatic cancer, a disease that also afflicted his sister, and he passed away on July 31, 2014, at age 72. An endowed fellowship was established in his name to support future fellowship training needs. A memorial garden was dedicated to him on the south-east corner of the old Fitzsimons Army Hospital (Building 500) as a tribute to his contributions to CU and his love of gardening.
Dr. Jerrold Olefsky was appointed Head of the Endocrinology Division in 1978, resulting in a tremendous upgrading and expansion of the Division. Dr. Olefsky recruited a number of new faculty members: Dr. Robert Eckel (1979), who came from the University of Washington with a special interest in studying diabetes and disorders of lipid metabolism; and Dr. Richard Robbins (1981), who was trained by Dr. Seymour Reichlin, and was interested in the study of neuroendocrinology, particularly somatostatin synthesis and release from brain cells and the control of the secretory process within the brain tissue. Dr. Kathryn Horwitz (PhD) from the University of Texas at San Antonio also joined the faculty (1979), specializing in the study of estrogen and progesterone receptors in various tumor tissues, especially breast cancer.
Dr. Olefsky also brought to this institution expertise in the study of diabetes, particularly focusing on the action of insulin and delineation of the role of insulin receptors in modulating insulin action. Among the outstanding individuals recruited during his tenure, in addition to Dr. Eckel and Dr. Robbins, included Drs. Orville Kolterman (MD), Theodore Ciraldi (PhD), Stephen Marshall (PhD), Boris Draznin (MD, PhD; 1980), Paulos Berhanu (MD; 1981) and Fred D. Hofeldt (MD; 1984). A tremendous amount of creative and innovative research was undertaken during this exciting and productive period. Other trainees and faculty included Drs. Robert Henry; Masashi Kobayashi, who subsequently went to Shiga Medical School in Kyoto, Japan; Mel Prince, who subsequently went to University of Texas Medical School Galveston; and Stuart Gray, who became Senior Registrar, Royal Infirmary, Edinburgh, Scotland. Dr. Timothy Garvey later became the Head of Endocrinology at the Medical University of South Carolina and then the Head of the Metabolism at the University of Alabama Birmingham. Dr. Mervyn Lifschitz was the Endocrinology and Diabetes Practice Director during these years.
The Endocrinology Division developed a degree of sophistication in both clinical care and research, ranking it consistently as one of the best in the nation. Dr. Olefsky received numerous honors and awards for his outstanding contributions to diabetes research. He served as President of the American Federation for Clinical Research, a very prestigious position. Dr. Sussman soon thereafter became the President of the American Diabetes Association (ADA). In 1983, Dr. Olefsky accepted an appointment at the University of California San Diego; Drs. Kolterman, Marshall and Henry accompanied him to UCSD. Dr. Robert Eckel assumed temporary leadership of the Division as Acting Division Head (1983-1985).

Dr. Fred Katz assumed the leadership of the Endocrinology Division in 1972 when Dr. Sussman was appointed Chief of Medicine at the Veterans Administration Medical Center. Dr. Katz contributed to the Division a strong orientation in general Endocrinology. While Dr. Katz was head of the Division, a number of fellows were trained in Endocrinology and ultimately entered private practice. New faculty appointed to the Division included Dr. Merrit Rudolph, who trained with Dr. Sidney Ingbar. Dr. Rudolph had a strong interest in thyroid disease and brought to the Medical Center in-depth knowledge in this area. Dr. Don S. Schalch came from the University of Rochester School of Medicine and had originally done his training with Drs. William Daughaday, David Kipnis and, subsequently, Dr. Seymour Reichlin. Dr. Schalch’s special interest was the pituitary gland, but also more broadly neuroendocrinology. He was responsible for the development of a number of immunoassays which were key to the advancement of knowledge in neuroendocrinology.
At this time the Division was quite effective; its five members were Drs. Katz, Rudolph, Schalch, Beck and Sussman. Fellows trained included Dr. Udo E. Heinrich, who became Associate Professor of Medicine at the University of Heidelberg, West Germany; Philip Burstein, who was initially an Assistant Professor of Medicine at the University of Colorado and later went into private practice and eventually into industry; and Dr. John M. Lock, Clinical Assistant Professor of Medicine, University of Massachusetts School of Medicine.
This was a period of transition, however, since Dr. Sussman was heavily committed to his duties at the VA Medical Center. Dr. Beck became the Associate Dean of Education in the School of Medicine and was no longer able to contribute in a major way to the Division of Endocrinology. However, Dr. Schalch continued to pursue the study of growth hormone and somatomedin metabolism. He was one of the leaders in this field, developing assays for measuring somatomedin and somatomedin-binding protein.
The Division underwent further transition when Dr. Katz left to enter the private practice of Endocrinology in Denver in 1976. There followed a period in which the Division was supervised by two acting heads, initially Dr. Sussman for a year (1976-77), followed by Dr. Schalch (1977-78). During this time, two notable Endocrinologists joined the General Medicine Department and worked also in the Endocrinology Practice, Dr. Richard L. Byyny (1977) and Dr. Mervyn Lifschitz (1978). Dr. Byyny later became Chancellor of the University of Colorado Boulder and Dr. Lifschitz went into private practice at Rose Medical Center in Denver.
Dr. Jenkins left the School of Medicine in 1968 to set up a private laboratory to conduct specialized endocrine and other laboratory tests. Dr. Karl Sussman was appointed Head of the Division and remained in this position from 1968 until 1972. Under the aegis of Dr. Sussman, the Endocrine Division focused on performing both basic and clinical research in Endocrinology. Dr. Paul Beck, who had previously been involved with studies of the effect of pregnancy on various aspects of carbohydrate metabolism, was investigating the effects of oral contraceptive agents on carbohydrate metabolism and insulin secretion.
Drs. Sussman and Beck were joined by Dr. Fred Katz of Loyola University, who had a special interest in renin-aldosterone metabolism. Dr. Katz brought to the Medical Center expertise in sophisticated assays for studying the dynamics of aldosterone metabolism as well as being able to focus on hypertension and various disorders of renin-aldosterone metabolism. It was an exciting period in the Division of Endocrinology and the program trained such outstanding individuals as Dr. Nick Alsever of Pueblo and Dr. Mel Stjernholm of Boulder. These individuals contributed significantly to developing Endocrinology outside Denver and set up a major referral practice throughout the state. In addition, these two physicians maintained a strong academic orientation, writing book chapters and articles in major medical journals.
Dr. H. Dalton Jenkins was the first full-time Endocrinologist in the Department of Medicine at the University of Colorado School of Medicine (1959-1968). He received his training in Endocrinology at the Peter Bent Brigham Hospital of Harvard Medical School, under the supervision of Dr. George Thorn. Dr. Thorn trained a number of other notable Endocrinologists, including Drs. Peter Forsham (who later led a prestigious Endocrinology Division at the University of California San Francisco), Donald Frederickson and John Leutscher. Dr. Jenkins came from this group of excellent investigators who made major contributions to the knowledge of adrenal cortical physiology and functions as well as delineating the pathophysiology of a number of disorders of the adrenal glands.
Dr. Jenkins was a remarkable individual with a tremendous thirst for knowledge. He was an exceedingly gifted teacher and clinician and represented perhaps the finest in terms of clinical endocrinology in the United States. The first fellow trained under Dr. Jenkins was Dr Oren Gum. Soon there followed a succession of fellows, including Drs. Janet Schemmel, Don Brown and Helen Morris. Dr Gum ultimately pursued the field of Rheumatology and became head of the Rheumatology division of Tulane University in New Orleans. Drs. Schemmel and Brown pursued an active private practice in Endocrinology as well as carrying out teaching functions at the School of Medicine. Dr. Schemmel remained a Clinical Professor of Medicine at UCHSC. Dr. Morris became a member of the National Jewish Hospital staff and conducted research focusing on the field of prostaglandins, holding the academic rank of Associated Professor of Medicine at the University. Dr. Robert Jaffe trained under Dr. Jenkins and became Head of the Department of Obstetrics and Gynecology at the University of California in San Francisco. Outstanding individuals who came from other countries to take fellowship with Dr. Jenkins were Drs. Louis and Andre Dayer of Geneva, Switzerland.
While Dr. Jenkins was Head of the Division of Endocrinology, a number of notable advances occurred in the field. Drs. Berson and Yalow developed the radioimmunoassay technique for the measurement of polypeptide hormones. This enabled the field to advance remarkably, not only from the standpoint of better diagnosis of clinical disease but also by improving our capacity to understand the basic pathology of many endocrine disorders. Radioimmunoassays were developed for the measurement of insulin, growth hormone, glucagon, parathyroid hormone, ACTH and a host of other hormones that are secreted by various endocrine glands.
The Division of Endocrinology expanded in 1963 with the recruitment of Dr. Karl Sussman. Subsequently, Dr. Paul Beck, who had trained with Dr. William Daughaday at Washington University, St. Louis, joined the Division and greatly strengthened the clinical and research activities of the service.
As the number of practicing Endocrinologists increased and more sophisticated laboratory procedures became available, Endocrinology within the community underwent significant expansion. Among those who entered private practice in Colorado were Drs. John Watt, Ray Gutin, Howard Kerstein and Harold Birenboim. There was a considerable increase in endocrine expertise in Denver, and Endocrinologists were practicing in Boulder, Pueblo, Greeley and Colorado Springs. Endocrine disorders could be appropriately diagnosed and treated in many communities throughout Colorado as well as at the University medical center.
