Patient Testimonials

  • I have been a patient of Dr. Perin for a long time and, to me, there is not no other Cardiologist that compares. I'm still alive at 83 because of him. Not only is he a top notch doctor but he is wonderful, very knowledgeable and has great sense of humor.

  • I transferred to Dr. Perrin after being a patient of Dr. Patrick Hogan for decades. Dr. Perrin is excellent, he listens, interacts, responds, and offers the very best care anyone could expect. His staff at Texas Heart Medical Group are also excellent. Anytime I have reached out to them, they have responded immediately. I have not experienced the level of care they offer at any other of my caregivers and feel very fortunate to have such an esteemed and capable physician.
