To be brief, Dr. Dieck saved my life by properly diagnosing my critical condition in time. Since then his care has been wonderful. My wife and I are deeply grateful. (or as she says, "MOST of the time!") Everyone on the Doctors staff has been great. Upbeat and friendly and I must give special kudos to Nurse Debbie Hardin who has been of great help to me. Thanks, y'all!

I know Dr. Dieck gives me the best care. He always listens and is always so friendly. I would not want to see any other doctor. I would recommend family or friends to see him. Hope he never retires.

My husband and I both saw Dr Dieck recently.He has been our physician for a number of years. He has always been very attentive and shown concern for any problem. He has a very friendly manner that makes us feel comfortable talking to him. He is very skilled in his profession.

I've been a patient of Dr. Dieck since I moved to the Austin area, 13 years ago.

After returning to Austin, I needed to find a new cardiologist, DR. Dieck was my doctor before moving to Buda/Kyle. Dr. Dieck was my first choice.

I have been a patient of Dr John Dieck's since 1999. In my not so humble opinion he is the finest cardiologist in the entire state of Texas. His nurse, Debbie Hardin, as are Nurse Cynthia Dolphus and PA Savannah Dagget are all rock stars. The rest of his staff, medical assistant and front office are top of the line. Professional, courteous and helpful. It just doesn't get any better than this. Ron Brock

Dr. Dieck is my new cardiologist as one of his wonderful partners retired. In the two visits I have had with him, he listened carefully to my questions and knowledgeably responded. My new prescriptions were correctly filled. I also met his new physician’s assistant.
