The OHSU Endocrinology Fellowship Program prepares individuals for rewarding careers in endocrinology and metabolism. Graduates of this program will be trained and fully equipped to function as clinical endocrinologists, clinical educators, or clinician scientists, depending on their individual career goals.

Our trainees are fully integrated into all aspects of our academically diverse Division of Endocrinology, Diabetes and Clinical Nutrition allowing for one-on-one working relationships between fellows and supervising faculty.  The OHSU-VA Endocrinology Fellowship Training Program is fully accredited by the Accreditation Council for Graduate Medical Education.

Program highlights


The joint Endocrinology Fellowship Training Program at Oregon Health & Science University (OHSU) and the Veterans Administration Portland Health Care System (VAPORHCS) serves to prepare individuals for rewarding careers in endocrinology and metabolism.

The two main training sites (OHSU and VAPORHCS) provide an ideal mix of patients and clinical settings to permit unparalleled breadth of both inpatient and outpatient experiences. We strive to provide this training in a diverse, inclusive, collegial educational environment where trainee well-being and professional development are among our utmost priorities.

Graduates of this program will be trained and fully equipped to function as clinical endocrinologists, clinical educators, or clinical scientists, depending on their individual career goals.

Program aims

  • To learn basic and advanced endocrine biochemistry, physiology and pathophysiology, that provide the basis for understanding endocrine disease.
  • To accumulate a critical mass of fundamental information and practical approaches for the diagnosis and management of endocrine disorders.
  • To acquire the technical and practical skills that are required by a consultant in endocrinology, diabetes and metabolism.
  • To acquire clinical skills in a progressive fashion and with increasing responsibility appropriate for a consultant in endocrinology and metabolism.
  • To acquire knowledge and skills necessary for providing cost-effective, ethical and humanistic care of patients with diabetes and disorders of endocrinology and metabolism.
  • To acquire knowledge and skills necessary for critical analysis of the endocrine literature.
  • To acquire skills in design and performance of hypothesis-driven endocrine research, and to participate in such research or equivalent scholarly activity.

Our academic faculty staff endocrinologists serve as teachers and mentors. Their various backgrounds result in an exceptional depth and breadth of clinical expertise. Our trainees are fully integrated into all aspects of our academically diverse Division of Endocrinology, Diabetes and Clinical Nutrition allowing for one-on-one working relationships between fellows and supervising faculty.

There are two fellows in each year of training. Generally, each academic year includes four months of inpatient clinical endocrine consultation and eight months of outpatient experience with research and independent study time. 

The fellows serve as leaders of the endocrine team, which consists of the fellow, internal medicine residents and medical students, with attending supervision. Clinical training is carried out at both the OHSU Medical Center and at the adjacent Veteran's Administration Medical Center.

The fellowship experience can be modified based on the trainee's career goals with responsibilities in both clinical and research fields.

Research training opportunities at OHSU include:

  • Time and financial support to complete advanced degrees in the Oregon Clinical and Translational Research Institute
  • Participation in human investigational studies in the NIH-funded Clinical Research Unit
  • Acquisition of skills in clinical, basic, translational, or health care delivery and outcomes research
  • Access to workshops on preparing research manuscripts, protocols, delivering effective scientific presentations

Outpatient experience takes place in half-day continuity outpatient clinics in general endocrinology and various subspecialties. All fellows participate in at least one continuity clinic over the course of their training. 

Our trainees hone their skills as educators by active engagement in formal and informal didactic activities targeted at all levels of medical training.

Additionally, all fellows participate in a variety of conferences, including a weekly core curriculum didactic series, city-wide clinical case series and journal club.

Our training program provides a supportive environment in which fellows assume graduated levels of independence in caring for patients.

Our patients come to us from culturally and economically diverse backgrounds, with a broad range of endocrine disorders, including:

  • Diabetes
  • Pituitary disease
  • Dyslipidemia
  • Bone and mineral disorders
  • Thyroid dysfunction
  • Adrenal disease
  • Endocrine neoplasia
  • Reproductive disorders
  • Clinical malnutrition

Fellows will acquire the technical and procedural skills necessary to enable them to provide complete clinical patient care services, including:

  • Thyroid ultrasound and biopsy
  • Insulin pump management
  • Continuous glucose monitoring
  • Interpretation of bone densitometry
  • Radioiodine scanning and therapy

Throughout the training experience, ethical and compassionate behavior and cultural competency are emphasized, as is the impact of socioeconomic factors on health care delivery, so that our graduates are fully prepared to negotiate the increasingly challenging practice environment.

Upon completion of our training program, all fellows will be fully competent to provide expert clinical care for individuals with endocrine and metabolic disorders, and/or to pursue investigative careers in clinical, translational or basic research.
