Endocrinology - Fellowship


Welcome to Pediatric Endocrinology!

The University of Colorado School of Medicine (CU SOM) Department of Pediatrics and Children's Hospital Colorado (CHCO) offer a three-year fellowship in pediatric endocrinology. In addition, the fellowship can be extended into a four-year fellowship if a fellow is doing a combined pediatric and adult endocrinology fellowship. Children's Hospital Colorado is a freestanding children's hospital with a full affiliation with the University of Colorado School of Medicine for training pediatric residents and fellows. Children’s Hospital Colorado is a top 10 best children’s hospital in the country and the Department of Endocrinology is consistently ranked within the top 15 best programs in the United States. We serve a diverse population from a large catchment area, in addition to Colorado, but also including Wyoming, Montana, North and South Dakota, Nebraska, Kansas, and New Mexico. The fellowship is fully accredited by the Accreditation Council of Graduate Medical Education (ACGME).

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 endocrinologists 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 consult service, general endocrine, diabetes and multidisciplinary clinics 

The first year of the Pediatric Endocrinology Fellowship consists of clinical training and incorporates some preparation for the second year, while the second and third year 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 assessed through both the Clinical Competency Committee (CCC) and Scholarly Oversight Committee (SOC)


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 (CHCO), University Colorado Hospital (UCH) and The Barbara Davis Center (BDC).
    • Fellows' clinical activity is primarily located at CHCO in Aurora, Colorado on the Anschutz Medical Campus (AMC).
      • Fellows have the opportunity to rotate at CHCO's other campuses/locations for elective rotations and/or shadowing opportunities throughout their fellowship. Refer to the list of Children's Hospital Colorado locations here.
  • Fellows spend a total of 6 months on the inpatient service; 3-4 in the first year, 1-2 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 (at the BDC), and a half month of adult endocrinology (at UCH).
  • Continuity clinic begins in the first year of fellowship allowing fellows to follow a cohort of patients.
  • In addition, fellows have the opportunity to shadow various multi-disciplinary clinics:
    • The Multidisciplinary Clinic at Children's Hospital Colorado on the Anschutz Medical Campus, sometimes called MDC, is an innovation space which aims to enhance the ability for clinics to provide coordinated care for children with complex needs. Each clinic has specialists, nurses, therapists, and other staff dedicated to caring for their respective patient population in a strategically designed, modular environment.
    • At Children's Hospital Colorado's Department of Endocrinology, pediatric endocrinology experts work with the following multidisciplinary clinics (including but not limited to):
      • Bone and Mineral Metabolism Program
      • Cystic Fibrosis Clinic
      • eXtraordinary Kids Turner Syndrome Clinic
      • Neuro-Oncology Clinic
      • Osteogenesis Imperfecta Clinic
      • Pancreatitis Clinic
      • Polycystic Ovary Syndrome Clinic
      • Prader-Willi Clinic
      • Sex Development Outcomes-Achieving Results Clinic
      • Thyroid Cancer Program
      • TRUE Center for Gender Diversity
      • X-Linked Adrenoleukodystrophy Clinic

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 consult service. They rarely have to go into the hospital for an urgent consult. Pediatric endocrinology fellows take call up to 5 days per month, and weekends are divided throughout the fellowship.


Fellows are expected to attend the following educational conferences (roughly 1-2 per week) during the fellowship program: 

Note: All conferences offer an in-person and virtual format to accommodate our team members' clinic and call schedules.

Fellows Academic Half Day: Second Thursday per month, 1-5 pm

Conference includes pediatric endocrinology fellows, program director/associate program director, 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 as well as methods for wellness and resiliency. During Fellows' Academic Half Day, all fellows are free from patient care responsibilities.

Pediatric Endocrine Case Conference: Second Monday and Fourth Tuesday per month, 11 am - 1 pm

Conference includes pediatric endocrinology fellows, pediatric endocrine faculty, staff (including but not limited to our amazing Pharmacy, Nursing and and Lab Teams). 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 or pharmacy.  

In addition, 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.

Another unique component of this conference is that we use this conference time to schedule quarterly joint BDC and Endocrine Meeting of the Minds, professional development and leadership trainings. 

Diabetes Conference: Tuesdays, 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, and much more. 

Endocrine Grand Rounds: Wednesdays, 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, etc.. 

Pediatric Endocrine Summer School Lecture Series: July-August, Dates and times vary

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: 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.

Department of Pediatrics Conferences

While these conferences are not required for fellows to attend, our fellows are encouraged to explore and attend ones that interest them. Some of our Pediatric Endocrinology Fellow Alumni become guest speakers at these conferences!

Department of Pediatrics and Other Research Conferences

There are multiple research focused conferences throughout the Anschutz Medical Campus, including at Children’s Hospital and the Barbara Davis Center. All research conferences are shared with the fellows as optional learning opportunities.

Scope of Research Training

Research is an important component of the pediatric endocrinology fellowship program. 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 and/or laboratory investigation.

In the first year of fellowship, 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 the fellowship program director and research director, fellows will select a Scholarly Oversight Committee (SOC) in the second half of the first year of fellowship 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
    • Assess feasibility of scholarly project 
    • Identify impediments to progress and completion of research program 
    • Provide fellow and mentor feedback and advice about research proposal and progress
    • Review the fellow’s scholarly project to ensure that the research program meets the requirement for sub-board eligibility of ABP 
  • 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. Additional SOC members may be recruited as needed by the fellow.

During the second and third year of fellowship, fellows are expected to spend around 75-80% of their time working on research projects under the direction and guidance of the fellow’s primary mentor(s).

  • Progress will be assessed by the research mentor, SOC and CCC.
  • Fellows will be encouraged to submit abstracts to national meetings, submit and publish 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.

We require fellows to complete a scholarly work product by the end of the pediatric endocrinology fellowship. While the minimal requirement of success is preparation of a scholarly research proposal, the SOC will regularly assess progress towards completion of experimental studies, submission of abstracts to national meetings, presentations of posters or oral presentations at national meetings, submission and publication of study results, and the submission of grant applications. Members of the SOC are also required to sign-off on the scholarly work and personal statement submitted to the American Board of Pediatrics for board eligibility.

Adult-Pediatric Endocrinology Combined Fellowship Training Program

The University of Colorado offers a 4-year combined Adult and Pediatric Endocrinology Fellowship Training Program at the Anschutz Medical Campus in Aurora, Colorado.

Created in 2014, this program is offered to graduates of med-peds residency training programs.

With Children’s Hospital Colorado and University of Colorado Hospital adjacent to each other on the Anschutz Medical Campus, trainees have ample opportunity to attend conferences at both institutions regardless of their specific hospital assignment.   

For more information, visit the Adult-Pediatric Combined Training Website.


Diversity / Equity / Inclusion


We are committed to creating a diverse environment for students, residents, fellows, and faculty. We believe that an environment of inclusiveness and respect promotes excellence and that a setting where diversity is valued leads to the training of physicians who are prepared to practice culturally effective medicine and meet the needs of the various populations we serve. Visit our Diversity, Equity, and Inclusion webpage for more....

Well-Being / Resilience

Be well

By embracing wellness and improving personal resiliency, physicians can reconnect with the meaning of their work and fend off stress. Reducing or eliminating burnout also has practical implications for the entire department such as improving patient safety, student advancement, and the overall campus environment.
