Our Providers

At Buffalo Rheumatology, we believe the best patient care starts with a personal connection. We take the time to sit down with you to discuss your medical history, other treatments you may have tried, and what to expect from your condition. From there, we create a customized course of treatment based on our years of experience and your particular condition.
