Review by Arthur ***** August 7, 2025

5/5
I met with Dr James Flynn after being released from CMC for Cardio problems and unrelated GI. He is one of the finest open minded doctors I have had the opportunity to have met. I left feeling like "he totally understood my situation". Time spent sharing and showing me details of my cardio workup, heart eco cardiogram. and other gave me much understanding and comfort.
