  • Dr Coudrey, you’re the “best of the best!” I’m blessed, fortunate and proud to have you for my doctor. You’re an excellent cardiologist who is kind, caring, warm and friendly. You will always be one of my favorite people.

    Sandra R.

  • Thank you for your time and analysis of my tests. Guess I'm good for another 10,000 miles! Than reason I am writing is to call your attention to the medtechs who put me through the paces on the stress test. First and foremost, they were professional, efficient, and skillful. In addition to these important qualities, add compassion, concern, tact, and interest. They made the experiences a pleasant one. Nice people. At my retiree meetings, I now have bragging right on who has the best cardiologist! Thank you, one and all.
