Geriatric medicine is its own specialty. Our physicians are trained in internal medicine or family practice prior to completing their fellowship in geriatrics.

We treat persons age 65 and older, providing both primary care and specialty referral-based care for healthy to chronically ill patients. We are experts at managing multiple medications, multiple chronic conditions and complex care needs. We take care of healthy, older, physically active persons and those living in assisted living facilities, but do not provide care for older persons living in nursing homes or other institutional care at this time.
