Our Internal Medicine Team is Now Accepting New Patients!

Staying well starts with your primary doctor. At Buffalo Medical Group, your primary care physician (PCP) is your first stop for medical care—and your partner in health. Our PCPs deliver comprehensive care that’s as convenient as it is compassionate, and always strives to keep you well.

We offer a comprehensive approach to patient care, giving you access to a team of primary care physicians, specialists, nurse practitioners, physician assistants, nurses, pharmacists, nutritionists, behavioral health specialists, and ancillary service and support personnel who work collaboratively to offer you a continuum of care that meets all of your health care needs.

We are a Patient Centered Medical Home, a recognition given by the National Committee for Quality Assurance (NCQA), for our partnership of care coordination between you and our providers.

Our PCPs are here to keep you well, offering a variety of preventive services. With convenient locations in the Northtowns, Southtowns & Downtown Buffalo, care is never far from home.
