The Endocrinology Clinic provides consultation and ongoing follow-up to patients who are referred by a primary care physician. The clinical spectrum of diseases seen by Dr. A. John Ryan reflects a broad array of common and unusual endocrine and metabolic disorders.

Physician referrals should include the patient's history, a physical, appropriate lab data and the reason for referral.

The clinic serves as a primary teaching site for the University at Buffalo School of Medicine and affiliated residencies and fellowships in endocrinology and metabolism. Along with Dr. Ryan, fellows, residents and students see patients.

To make an appointment or for more information, call (716) 898-3147 or (716) 898-3152.
