"Ever since Hartford Healthcare acquired Primary Care Physicians of Fairfield at 425 Post Road, it has been a steady downhill decline. Now I am trying to call their office... and I get “Emma”, their AI receptionist who transfers me to every where except 425 Post Rd."

— Birdeye (Primary Care Physicians of Fairfield)

"I’ve been a patient since March ‘25, Fairfield Family Health is a calming environment. You are heard and never rushed."

— LocalityBiz (Fairfield Family Health)

"Although I have had my primary care doctor changed a few times here, I like that you are able to get almost all tests done at one location. The ability to walk in without an appointment is great when something unexpected comes up."
