I can not say enough good things about Dr. Theisz. He is by far the best Doctor I have ever been to. He is extremely knowledgeable, friendly and just an outstanding Doctor. I will never go anywhere else. He is 1 in a million.

The reception staff are not overly friendly, but they are professional and seem efficient. The nurse/technician staff have been very friendly. Dr. Theisz himself is a great listener and displays a genuine interest in the patient as a person as well as in their health. I was unhappy with my last physician and my wife, who works in the medical field, heard great things about Dr. Theisz.

I can't speak highly enough of Dr. Theisz. He is friendly, attentive, knowledgeable, and has an easy manner. He clearly cares about his patients and takes the extra effort to provide them the best care possible. After recently receiving concerning test results, I was called directly by Dr. Theisz to discuss. He clearly listens to patients and works to ensure that you are an informed partner in your health decisions. His is not afraid to be honest about what he does and does not know about your medical condition. He has clearly chosen to invest in maximizing technology for your health records and ease of filling prescriptions and tests, rather than a fancy waiting area. Also, once an established patient, I have always been able to get an appointment the same day or within a few days.

He's a great listener. Never feel rushed. I feel he is out for the patient/me and not the insurance companies.

Never waited more than 10 minutes to be seen. His office staff remembers me each time I call or come in. They are extremely friendly and attentive. Dr. Theisz is an amazing doctor. He is patient, careing, knowledgable, techno savy and an all around great guy. I was unhappy with my daughters pediatric doctor and switched her to Dr. T without a problem. I would recommend him to all. He is an EXCELLENT doctor and I wish my other doctors were just like him.

He is very personable and thorough. I can't say the issue is resolved though.

Payment amount is after deductible. Dr Theisz is very computer literate and uses a tablet pc to help keep up with all the information that he requires regarding history.
