Dr John Dieck MD is the best Cardiologist in Austin! He's taken care of me for over 15 years as well as my mother and father. I trust his expertise and he is so caring and thorough during our visits.

I have been seeing Dr. Dieck for ten years since first meeting him while I was in hospital for pneumonia. I see him or his assistant every six months and he and the staff are excellent. They all care about and monitor my health. I highly recommend Dr. Dieck and Texas Heart & Vascular.

I've been a patient of Dr. John Dieck since 2004, and I can say without hesitation that he is an exceptional cardiologist. Over the years, he has guided me through routine check-ups, diagnostic tests, and complex concerns with professionalism, deep knowledge, and steady reassurance. Dr. Dieck listens carefully, explains everything thoroughly, and never rushes through an appointment. He has earned my complete trust--both for his clinical expertise and his kind, thoughtful care. I always leave his office feeling confident and supported. If you're looking for a cardiologist who combines decades of experience with genuine compassion, Dr. Dieck is the one to see. I'm deeply grateful to have him as part of my long-term care team.
