Dr. O’Connor provides exceptional cardiology care. He listens to concerns, is caring/compassionate, discusses and provides options for care. His clinical and administrative teams are outstanding!! I am grateful and thankful that I am a patient in their practice.

From the moment that I walked through the door, the entire Staff was incredible. Reception was great, Intake was fantastic and Dr. O’Connor was amazing. He took the time to listen to me and is willing to investigate the issues to get to the root of the problem. I am so happy that we were referred to this Practice!!
