I have never been dissatisfied with Dr. Denys. I’ve always felt that he is truly concerned with my health and well being. My only concern is, when and if he retires who I will have to choose to replace him. I’m hoping he will give me guidance on that decision. In my opinion, he is irreplaceable.

I drive roughly 40 miles from Patterson to Thibodeaux Louisiana to see Dr. Denny. There are plenty of Heart doctors closer by, but I will continue to make that trip as long as he is working.
