Endocrinology - Fellowship

City Park Landsacpe


The University of Colorado School Of Medicine's Department of Pediatrics and Children's Hospital Colorado offers a three-year fellowship in Pediatric Endocrinology. The goal of the fellowship is to provide physicians who are board eligible in pediatrics with in-depth training in endocrinology that will prepare them for a career in clinical or academic medicine. Fellows rotate at 3 primary teaching sites, Children's Hospital Colorado (CHCO), University Colorado Hospital (UCH), and The Barbara Davis Center (BDC). Our three year program offers:

  • Superior academic subspecialty training in a professional, collegial atmosphere
  • One-on-one working relationships between fellows and supervising faculty
  • Endocrinology outpatient clinics and inpatient hospital consult services
  • Experience with high volume and wide array of endocrine problems, ranging from common to exotic
  • Diabetes Unit for training of patients in intensive insulin therapy programs
  • Endocrine case conferences, journal clubs, weekly endocrine grand rounds, and research conferences
  • Participation in the education of  residents, medical students, and PA’s
  • Continuity Care Clinic and Multi-Disciplinary Clinics

Program Aims 

  • To prepare future pediatric endocrinologists to provide innovative, patient-centered, comprehensive, high quality, evidence-based care for pediatric patients and families. To prepare future pediatric endocrinologists to focus on promoting patient safety and quality improvement.  To prepare future pediatric endocrinologists to communicate consistently and effectively with patients, families, and referring providers, enabling them to serve as a resource across the state and country

  • To provide structured mentoring to help future pediatric endocrinologist develop their optimal career paths.  To provide outstanding opportunities in conducting and disseminating (basic science, translational, clinical, educational) research and quality improvement methodology that prepare fellows for successful careers in academic pediatrics.

  • To promote a collaborative culture and develop (or create or ensure) program safeguards which will foster individual wellness, and to teach trainees strategies to build resilience and minimize burnout.

  • To build and maintain an infrastructure to recruit diverse fellows and provide an inclusive learning environment that promotes and celebrates differences.


Scope of Clinical Training

Training for fellows in pediatric endocrinology involves intensive clinical training in all aspects of clinical pediatric endocrinology. The large volume and broad range of endocrine pathology seen by Children’s Hospital endocrinologists ensures an optimal clinical experience for endocrine fellows.

  • Fellows will be trained in the following areas:
  • Endocrine focused history and physical examination
  • Interpretation of growth charts
  • Performance and interpretation of endocrine related diagnostic tests
  • Care of patients in the outpatient, inpatient and intensive care 

The 1st year of the fellowship consists of clinical training and incorporates some preparation for the 2nd year, while the 2nd and 3rd years consist mainly of research with some clinical training (continuity clinics, inpatient consultation). During year one of the clinical track you will identify an area of research interest and a mentor for pursuit during the second year.


  • Fellows will communicate with attending physicians and consulting services
  • Fellows assume progressive responsibility for patient care
  • Fellows are expected to actively seek the most up-to[date information to guide practice
  • Fellows take an active role in teaching of medical students and residents through bedside teaching and the participation in bedside teaching
  • Fellow progress will be assess through a Clinical Competency Committee (CCC)


All fellows are directly supervised by faculty members (CHCO, UCH, or BDC) specific to that rotation and by the inpatient consult attending for the inpatient consultation rotation. This attending physician shall be available at all times to the endocrine fellow. It is the responsibility of the fellow to communicate effectively and in a timely fashion with the attending physician as well as other members of the Endocrine Faculty. At each stage of training, the goal is to provide a level of supervision that ensures patient safety and maximizes education while promoting the trainee’s sense of independence and autonomy

Clinical Schedule

  • Clinical activity occurs at Children’s Hospital Colorado, University Colorado Hospital or The Barbara Davis Center
  • Fellows spend a total of 6 months on the inpatient service, 4 in the first year, 1 in the second year and 1 in the last year
  • Fellows spend 4-5 months in their first year in outpatient medicine including endocrine clinics, diabetes clinics and a month of adult endocrinology
  • Continuity clinic begins in the first year of fellowship allowing fellows to follow a cohort of patients

Call Responsibility

Call for pediatric endocrine fellows are at home call.  They are required to answer phone calls from parents of patients, outpatient phone consults and inpatient consults.  They rarely have to go into the hospital for an urgent consult.  First year pediatric endocrine fellows take call up to 10 days per month, including one weekend.  Second and third year pediatric endocrine fellows take care up to 7 days per month, including one weekend. 


Fellows are expected to attend the following conferences during the fellowship program: 

Case Conference – 2nd Monday and 4th Tuesday 11 am-1 pm
Conference includes pediatric endocrine fellows and pediatric endocrine faculty.  Cases are brought by both fellows and faculty for discussion and review.  Fellows present a more formal case with a detailed literature search 6 times per year during their first year.  This is also the forum for discussion of topics related to the laboratory. 

Journal club is a component of this conference. Second- and third-year fellows present 2-3 times per year. Journals are reviewed by the presenter to identify articles that are pertinent to pediatric endocrinology and diabetes. Reviewers select 3-5 articles for detailed discussion. Fellows are encouraged to select 2-3 articles for more in depth discussion of study design, statistics, and interpretation of results. This facilitates skill in critical reading of the literature, analysis of study design, statistics, extrapolation of research studies to clinical care of children with diabetes and other endocrine problems.

Diabetes Conference – Tuesday 12-1 pm 
Conference includes pediatric endocrine fellows and pediatric diabetes faculty.  Endocrine fellows present in the conference annually.  Topics include research in progress, clinical topics related to diabetes care, instruction on effective reading of the literature. 

Endocrine Grand Rounds – Wednesday 8-9 am 
Conference includes pediatric endocrine fellows and pediatric endocrine faculty, endocrine fellows, and faculty.  Endocrine fellows present once as a first-year fellow.  Topics include challenging endocrine cases, updates to clinical practice of endocrinology, invited speakers from across the country. 

Fellows Academic Half Day - 3rd Wednesday 12:30-4:30pm
Conference includes Dr. Barker pediatric endocrine fellows and other endocrine and diabetes faculty members. This conference includes our board review course (Fundamentals of endocrinology), clinical guideline review, review of cases with experts and training in research methods and methods for wellness and resiliency.

Pediatric Endocrine Summer School – Monday, Tuesday, Wednesday (July-August)
Conference consists of varied topics pertinent to the clinical care of children with diabetes and other endocrine problems.  Presenters are faculty in the division of pediatric endocrinology and the Barbara Davis Center.  The purpose is to provide a broad overview of the general topics of pediatric endocrinology and diabetes and provide the fellows with a foundation for the clinical care of children with these disorders.

Quarterly Endocrine Meeting (QEM)- Every 3 months Monday 8 am-12 pm
Endocrine and diabetes faculty and fellows attend this conference.  Conference includes an hour of didactic lectures from disciplines throughout the University (radiology, urology, genetics, reproductive endocrinology, etc.), time for morbidity and mortality.  Conference includes an hour for the discussion of disorders of sexual differentiation in a multi-disciplinary team.

Multiple research focused conferences throughout the Medical Campus, including at Children’s Hospital and the Barbara Davis Center – Required as appropriate for mentored research project.

Scope of Research Training

Research is an important component of the pediatric endocrine training program and training in research methods begins in the first year.  The goal is to provide trainees with an intensive introduction to the principles and techniques of clinical or laboratory investigation.

In the first year, fellows have 1-2 months dedicated to research to allow for the identification of a mentor and a project. Fellows will then prepare a research proposal with the guidance of the mentor.

  • With the guidance of Drs. Barker, Nadeau and Zeitler, fellows will select a Scholarly Oversight Committee (SOC) to help oversee the research training period
  • The SOC is composed of at least 3 faculty members who:
  • Meet with the fellow as a group at least twice per year
  • Review the training progress of the fellow
  • Making recommendations to the fellow regarding aspects of their progress.
  • Requirements for the SOC include one pediatric endocrine faculty member, another endocrine faculty member (either pediatric or adult) and a member outside of the divisions of pediatric and adult endocrinology.

During the 2nd and 3rd year of fellowship, fellows are expected to complete 2 years of research training.

  • 75% of their time working on research projects under the direction of a primary mentor
  • Progress will be assessed by the research mentor, SOC and CCC
  • Fellows will be encouraged to submit of abstracts to national meetings, submit and publish of study results and consider submission of grant applications
  • Under the guidance of the research mentor and SOC, educational courses offered through the Anschutz Medical Campus will be identified and completed.

Subspecialty-Specific Curriculum

Pediatric endocrine fellows will be trained to become proficient in endocrine-focused history and physical exam skills, interpretation of growth charts, learn appropriate selection, performance and interpretation of endocrine-related diagnostic tests, and integrate this knowledge base to develop appropriate management plans for patients with endocrine disorders referred for outpatient and inpatient endocrine consultation. During the last two years of the training program they will become highly skilled in the field of pediatric endocrine research, ready to assume leadership roles in the nation’s biomedical and behavioral research efforts in pediatric endocrinology. Lists of mandatory and recommended conferences are detailed in the Clinical Training Tab under conferences.
