Centra Internal Medicine (Sun City) Reviews

Heather Mednansky is the most empathic, warm and knowledgeable NP I have ever encountered. She takes care of me like no other health care provider has. She is patient and so very kind. I drive 120 miles round trip to receive this excellent care.
Mara Scaramella was excellent. She was extremely attentive, asked a ton of questions, and just all around knowledgeable. Very much recommend Mara and I will now use her for any primary care medical treatment moving forward! Thank you for making me feel comfortable and at peace.
NP Heather is always nice and easy to talk to. She takes time to listen and answer all our questions. We would definitely recommend this clinic to everyone and so for Dr. Sahni, Manish. Centra Internal Medicine and the rest of its staff, from the MA’s and those at the front desk, they are all nice and have great customer service.
