Two tracks are available to the potential trainee, a "clinical" track and a "research" track. Both tracks fulfill requirements of board eligibility for endocrinology and metabolism boards.

The research track, which is partially funded by the National Institutes of Health (NIH) and peer-reviewed, offers two years of research training, and is aimed at preparing the fellow for competitive academic positions. It can be individualized to coincide with specific career goals.

Trainees who enter the clinical track can later cross over to the research track on a competitive basis.

Clinical Training/Track
The large volume and broad range of endocrine pathology seen by Mayo Clinic endocrinologists ensures an optimal clinical experience for endocrine fellows. Endocrinology outpatient clinics and hospital services are very active and are supported by state-of-the-art laboratories, pathology and surgical services.

During year one of the clinical track you will identify an area of research interest and a mentor for pursuit during the second year. Many times the final touches of the project(s), such as abstract and manuscript preparation and presentation of findings, continues into the third year.

Rotation Descriptions

Endocrine Outpatient Clinics
The outpatient practice of endocrinology at Mayo Clinic is one of the richest concentrations of endocrine pathology in the world. Fellows benefit from the opportunity to evaluate and manage these patients under the one-on-one supervision of internationally recognized experts in clinical endocrinology. The clinics include diabetes/metabolism, thyroid, bone/calcium, pituitary-gonad-adrenal, nutrition, lipids, obesity, and women's endocrinology.

Diabetes Unit
Fellows and consulting staff supervise the care and, along with nurse educators and dieticians, educate patients with diabetes who are beginning intensive insulin therapy, including multiple daily injection and insulin pump programs. This provides the fellow with extensive experience in the institution and maintenance of this state-of-the-art management tool.

Endocrine Testing Center (ETC)
The ETC, located in the endocrine outpatient area, performs over 4,000 specialized diagnostic procedures of static and dynamic hormone function testing annually. In addition over 800 fine needle aspiration biopsies of the thyroid are performed by consultants and fellows. Time spent here provides the fellow the opportunity to gain experience in the conduct and interpretation of these specialized endocrine procedures.

Nuclear Medicine and Endocrine Imaging
Endocrine fellows have the opportunity to gain experience in specialized endocrine imaging such as nuclear medicine, ultrasound, CT and MR on an elective basis.

Hospital Services
Rotations on the Endocrine and Diabetes Consulting Service provide an opportunity to develop expertise in initial consultations and the management of glucose control and diabetes-related complications of hospitalized patients. Rotations on the Nutrition Support Service allow trainees to acquire experience with cost-effective use of parenteral and enteral nutrition.

Elective Rotations
Time within the schedule is set aside during both the first and third years for exposure to endocrine related topics of a more elective nature. Available rotations include hypertension, Renal Stone Clinic, Wound Healing Center and Vascular Center. Other topics may be pursued based upon personal interest. It is also possible to pursue elective opportunities at the Mayo campuses in Jacksonville or Phoenix/Scottsdale.

Didactic Training
Clinical conferences, seminars, small discussion groups, journal clubs and one-on-one instruction are all an integral part of the Endocrinology Fellowship.

During your training you will attend the following:


  • Endocrine Research Seminar Series
  • Endocrinology Journal Club (monthly)


  • Endocrinology Grand Rounds
  • Internal Medicine Grand Rounds


  • Case Conferences: Thyroid, Diabetes, Nutrition, Lipid


  • Case Conferences: PGA, Parathyroid/Bone, Pediatric, Reproductive

Research Training/Track
Endocrine research training opportunities at Mayo Clinic are exceptional. A wide range of laboratory-based and clinical research programs are available in both the clinical and research tracks. The research track, partially funded by the NIH, has consistently prepared interested fellows for competitive academic positions.

The Division of Endocrinology & Metabolism has an internationally recognized research faculty, most of which is based in the Endocrine Research Unit, located at Mayo Clinic Hospital, Saint Marys Campus. In addition a number of members of other divisions and departments on the Mayo Clinic campus pursue endocrine related research.

When you enroll in the research track, you will undertake an in-depth research project under the direction and supervision of one of these staff consultants. The 15-month clinical experience is individualized to coincide with your career goals and fulfills subspecialty certification requirements.

  • Research

The professional diversity of Mayo Clinic's endocrine faculty and their research interests are two of our greatest strengths. Detailed descriptions of their laboratory-based areas of investigation are documented on Mayo Clinic's Division of Endocrinology, Diabetes, Metabolism, and Nutrition Research site.

Current clinical studies include:

  • Drug treatment trials for diabetic neuropathy and nephropathy
  • Evaluation of insulin analogs
  • Development and assessment of a diabetes electronic medical record
  • Assessment of caloric requirements of critically ill patients
  • Determination of prognostic factors in thyroid carcinoma
  • Trial of radiotherapy treatment of Graves' ophthalmopathy
  • Osteoporosis epidemiology and therapeutic trials
  • Evaluation and treatment of patients with primary hyperparathyroidism or familial disorders
  • Development of diagnostic tests for Cushing's syndrome, pheochromocytoma and primary aldosteronism

Publication of research is supported by excellent editorial services. If you want to obtain independent investigative careers receive assistance in preparing research grants to pursue funding.

Conference Presentations
As an Endocrinology fellow, you will be asked to present conferences on a regular basis. Each fellow is responsible for directing one or two case conferences each month.

You also are responsible for one Endocrine Grand Rounds during the third year of training. Most fellows also present their research findings at a Tuesday Endocrine Research Seminar.

Teaching Opportunities
Endocrinology Fellows participate in the education of internal medicine residents and visiting medical students. You also will assist in teaching endocrine physiology and pathophysiology to first and second year Mayo Medical Students.

Research Topics
During the research year or years, fellows are expected to attend courses provided by the Mayo Graduate School on design of clinical research and research statistics as well as additional course work in molecular biology, immunology or biochemistry at the discretion of the individual trainee.

Case Studies
During your Endocrinology Fellowship, you will prepare case study presentations. You will present the pertinent information of an interesting case, conduct an in-depth discussion of that case and create a current bibliography.

Call Frequency
Your call schedule will vary by individual rotation. Mayo follows the recommendations of the Accreditation Council for Graduate Medical Education. Because much of the training is outpatient based, as is the clinical practice of endocrinology, many of the rotations do not require night call schedules.

Moonlighting is permitted for licensed residents and fellows beyond the PGY-1 level. Moonlighting activities may be scheduled during those times when you are assigned to consultative or outpatient rotations. Moonlighting should not interfere with required learning and must not violate the ACGME's work hour rules. Moonlighting should not compromise your education, but rather enhance it.

However, please note that most non-immigrant visas (J-1, H-1B) do not allow an international to participate and receive any form of compensation; this includes moonlighting activities.

To ensure that you acquire adequate knowledge and develop your technical skills, your performance will be monitored carefully during the course of your fellowship. You will be evaluated formally by your supervising faculty member after each clinical rotation. In addition, you will regularly evaluate the faculty to ensure that your educational needs are being met.

Career Development
You will meet periodically with various faculty members, administrators and the program director to discuss your career goals. Mayo recruits many of its staff physicians from its own training programs. Thus, when you successfully complete the Endocrinology Fellowship, job opportunities may be available at one of Mayo Clinic's group practices.

Graduate Outcomes
The most important sign of the success of any training program is how graduates fare after they begin their careers. More than 100 physicians have graduated from the Endocrinology Fellowship Program and practice in 25 states and 10 foreign countries. More than 60 percent hold academic appointments at their respective institutions. Many have demonstrated professional leadership in their medical careers.

Additional Training
At the conclusion of the Endocrinology Fellowship, you may wish to continue your graduate medical education through the Mayo Clinic College of Medicine. The school offers advanced academic degrees (masters and/or doctorate).

If you pursue these advanced degrees, you will continue to receive in-depth, daily, one-on-one training with a consultant. You also will also have the opportunity to increase your own supervisory and administrative skills. Contact your faculty adviser for more information about these opportunities.
