We've Redesigned the Way We Provide Care

Keeping yourself and your family healthy might seem like a huge challenge right now. At UR Medicine Thompson Health, we're making it easier. We've redesigned our whole system of care.

Enhanced safety standards have been implemented to keep you and your family safe when coming into our facilities. And, we also have options to treat you without you having to come into the office, if you'd prefer.

Appointments and inquiries can be made in the following ways:

Your provider will decide whether a telehealth or in-office visit is most appropriate for your situation. Insurance companies are now covering telemedicine (online video) visits to help you maintain access to care during the pandemic.

* It is important that you keep up with your prescribed medications. Remember that the drive-thru at CMG Pharmacy is also open at 335 Parrish Street in Canandaigua. No need to even get out of your car.

Internal Medicine

Thompson Health Canandaigua Medical Group

 Part of F.F. Thompson Hospital 

Internists are experts in adult medicine and care for the whole patient. They solve problems with chronic and multiple illnesses no matter how simple or complex. Of all primary care physicians, the “doctors of internal medicine” (also called “internists”) are unique in their focus on adult medicine. They bring to patients an understanding of wellness (disease prevention and the promotion of health), women’s health, substance abuse, mental health, as well as effective treatment of common problems of the eyes, ears, skin, nervous system and reproductive organs. They are specially trained to solve complicated diagnostic problems. They handle severe chronic illnesses and situations where several different illnesses may strike at the same time.

When other medical specialists, such as surgeons or obstetricians, are involved, they coordinate their care for the patients and manage difficult medical problems associated with that care.
