“Good visit with Erin M Fly, DO”
July 16, 2025
“This is my first appointment with Dr. Erin Fly, who was recommended to my spouse & myself by a long-term neighbor who has been her patient for years. Dr. Fly was very kind & very thorough in reviewing my medical history, asking about what medical concerns I had & advising me about tests &/or procedures that might be appropriate given my age, medical history & physical condition. She made me very comfortable that I had made a good choice of her for my new Primary Care physician, & of the group practice as a whole for my spouse and myself going forward.”
