Endocrinology Fellowship (Minnesota)

Endocrinology fellows look at textbook together.


The three-year Endocrinology Fellowship at Mayo Clinic's campus in Rochester, Minnesota, is designed to deliver well-rounded clinical and research training to prepare you for the breadth and depth of clinical practice of this subspecialty.

As a fellow, you have access to a training experience that is broad, highly specialized, and offers:

  • A professional, collegial atmosphere with one-on-one working relationships between fellows and faculty
  • A long-standing tradition of highly efficient and safe patient-centered care, creating an ideal setting for professional development where you:
    • Focus on education, not "navigating" your patients through a system
    • See any and all patients, as there are no "private attendings" at Mayo Clinic
    • Experience a large volume and variety of endocrine disorders ranging from common to exotic
    • Work with the on-site Endocrine Testing Center for conducting specialized diagnostic or therapeutic protocols, which is staffed by endocrine nurse specialists
    • Enjoy world-class in-house clinical laboratory services with rapid results
    • Have an outpatient Diabetes Unit for training patients in intensive insulin therapy
  • An established balance between education and service with:
    • Abundant time to devote to academic development throughout training (not just during research blocks)
    • Clinical assignments that reflect what endocrinologists do in clinical practice (over 80% of clinical time is spent in outpatient subspecialty clinics)
    • Conferences five days a week
    • Generous supported travel benefit
  • The opportunity to acquire skills in clinical, basic, translational, or health care delivery and outcomes research (or a combination) during the second year and third year including:
    • A Clinical Scholar Track or a National Institutes of Health (NIH)-Sponsored Track
    • A Clinical Research and Trials Unit for conducting human interventional physiology studies
    • Protected time to complete Mayo Clinic Graduate School of Biomedical Sciences individual coursework without cost or advanced academic degrees in the Center for Clinical and Translational Science
    • Academic skills workshops including how to write a research manuscript, prepare a research protocol, write a grant proposal, give a presentation, and be an effective teacher

Mayo Clinic's 44 staff endocrinologists serve as teachers and mentors. Their various backgrounds result in an exceptional depth and breadth of clinical expertise and research opportunities for fellows who are fully integrated into all aspects of our academically diverse Division of Endocrinology, Diabetes, Metabolism, & Nutrition.


The Endocrinology Fellowship is fully accredited by the Accreditation Council for Graduate Medical Education.

Program history

The Endocrinology Fellowship at Mayo Clinic in Rochester, Minnesota, was established in 1969. Since that time, 188 fellows have completed their training in this program. We anticipate that four trainees will complete this program annually.

Frequently asked questions

Why a three-year program if only two years are required for board eligibility?

For those interested in a research career, a flexible third year which offers more protected time for academic development, pilot studies, acquiring preliminary data, grant writing, and preparation for a junior faculty position is necessary and desirable.

Those choosing to pursue a Clinical Scholar track discover that a second year of clinical training allows one to grow beyond competency and advance their clinic research skills even further.

Additional exposure to challenging cases, electives in endocrine related disciplines, and the opportunity to develop a subspecialty focus (such as thyroid neoplasia, women’s health, transplant endocrinology, or transgender medicine, to name a few) under the guidance of expert clinicians proves invaluable when seeking to develop a niche within an institution, region, or practice.

The key to value in the third year of training is our flexibility and commitment to align this advanced training experience with your career goals as determined by you and your career mentor. Ultimately, we have found a third year of training pays dividends for years to come.

Are there equal opportunities for non-green card holders or noncitizens for a research career?

Although we have a NIH T32 training grant, our three-year fellowship is internally funded so that highly motivated non-citizens can dedicate 12 to 18 months of their fellowship for research and academic development.

With support from the training grant, U.S. citizens could use the training grant for up to 24 months of research time during fellowship and an additional year beyond fellowship to extend their laboratory research training and to write grants, or seek a K award.

Given Mayo Clinic draws patients from around the world, will I mainly see “zebras”?

We are the main healthcare provider for residents of Southern Minnesota, North Iowa, and Southwest Wisconsin. While we have many national and international patients with complex and unusual disorders, fellows see plenty of “bread-and-butter” endocrinology, especially in their first year. This includes a sizable immigrant population in Rochester that adds to the diversity of our employees and patients.
