All three OHSU services are ranked among the nation’s best by U.S. News & World Report. We’re also part of the OHSU Brain Institute, a national leader in innovative research.

Pituitary disorders involve many body parts and systems. Our integrated care, with experts working together across specialties, is crucial to giving you the right diagnosis and treatment.
You’ll benefit from our:
Team approach: We bring together any expert you need, including specialists in the hormone system, nervous system, vision, tumors, skin, gynecology and more.
Care as long as you need: We provide care as long as needed — sometimes for life. Long-term services include classes and support groups for you and your loved ones. We also regularly update your primary care doctor to keep all your providers in the know.
A focus on your well-being: We emphasize not only effective treatment but how treatments affect your quality of life. We place a high priority on managing side effects and helping you do the things that are important to you.
Diagnostic precision: Our pituitary specialists understand the nuances in symptoms of even rare pituitary disorders. You can count on our expertise for an accurate diagnosis, even for pituitary disorders that are often missed or misdiagnosed elsewhere.
Skilled neurosurgeons: Our neurosurgeons offer the highest level of skill and experience for complex pituitary procedures. They use minimally invasive techniques, with little scarring, less pain and less risk of complications.
Convenience: You’ll find all the specialists and tests you need in one place. We strive to give you answers, whether for a first diagnosis or a second opinion, in one day.
We’re happy to offer second opinions and to discuss cases with doctors in the community. Patients come to us from across the U.S. for answers about these disorders, which can be rare, complex and difficult to pinpoint. We can also offer guidance on treatment options.
Often, we can provide answers in one day. Our location on Portland’s South Waterfront, near highways and services, is convenient for out-of-town and out-of-state patients.
Research and clinical trials
- We offer patients access to a wide range of clinical trials to test new approaches. We will talk with you about trials that may be right for you.
- We played a leading role in designing and running clinical trials that led to approval from the U.S. Food and Drug Administration for medications to treat acromegaly and Cushing disease.
- Dr. Fleseriu led a clinical trial studying patients’ quality of life during acromegaly care. The results helped improve treatment effectiveness and patient experience. Our team has been a leader in focusing on patient well-being, which is now an accepted best practice.
