    • 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 (>75% 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):
    • A Clinical Research and Trials Unit for conducting human interventional physiology studies

Frequently asked questions (and answers)

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

Our two-year fellowship is internally funded so that highly motivated non-citizens can have the same opportunities for research and academic development as all other trainees.

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.
