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.

This is a well run practice. I get in to the exam room within 10 minutes of check in. Dr. Dieck spends time with me and answers all of my questions. Also I have access to his nurse between visits which is a great resource.

His personality and experience are extremely important to me as a patient because he does not make you feel that you are wasting his time; for I have experience this in the past even though I worked as a nurse for 54 years.

Follow up consultations. Have had Dr Dieck and his nurse Debbie taking care of me since I moved to Austin many years ago. I could not have any better care. Highly recommend both Dr Dieck and Debbie to anyone needing this type of care. They have taken care of me and also my wife. No better place to go for a doctor looking out for you.
