Dr. Cox is just an outstanding doctor and all around great guy. His knowledge of the heart and it’s operation is just top notch and he’s always been there whenever I need him. The nursing staff is a real treat to talk to and they’re very supportive. I like the new building they’ve been in for a couple of years now and I did a test down the hall from the doctors office just last week. Devin did the test and he was a real treat to deal with. Overall a 10/10!

The staff and Dr. Cox are very polite, concerned for my wellbeing and professional.

Aug 22, 2026
My visit served a twofold purpose: 6-month check-up and pre-op clearance. As usual the support staff immediately checked me in and the wait to be taken to the exam room was very prompt. The medical tech was very personable and efficient . . . and knowledgeable. The transition between the medical tech and Dr. Cox coming into the room was very short, which I greatly appreciate. As always, Dr. Cox knew of my recent visit to the ER due to an accidentally leg injury. We discussed other problems and he referred me to a specialist. I am always pleased with having Dr. Cox as my cardiologist.
