Dr. Dieck is knowledgeable and very through with his patients! I would recommend him to anyone who needs a cardiologist!
in Austin, TX |
Dr. Dieck in my opinion is the greatest cardiologist. He has been my doctor for 15 years and has always solved my health issues. I highly recommend him.
in Marble Falls, TX |
I became a patient of Dr. Dieck after a very bad experience with another cardiologist with a different medical service three years ago. The difference was like day and night as far as the care and understanding I received were concerned. In my three years with Texas Cardiovascular, I have received nothing less than the best in knowledgeable service and care. Dr. Dieck is the very best and I would not trade him for all the other cardiologists in Austin..
in Georgetown, TX |
Dr Dieck and his staff are the best I have dealt with in my 80 years. They are professional, knowledgable, and dedicated to the patient. I'm pretty sure I wouldn't be here if not for them.
