If you have to go to a doctor, this is the one to see. He’s been my cardiologist for three years now. I’m very satisfied.

Dr. Drennan always takes his time with his patients to listen very carefully to each concern they have and never makes them feel rushed. I always feel like he has time for me and my health and that I'm not just another number to check off of a list. Dr. Drennan makes his patients feel seen and heard and that is the absolute best quality a doctor can have! 5 stars every single time!
