I love Dr. Gresham and his staff. I was concerned when I first started going there because I just saw the PA, who is very nice and knowledgeable. Now after meeting with Dr. Gresham several times, I feel very comfortable with him. He is proactive, caring and gives you his complete attention. (and his good sense of humor is a big plus) Because he spends so much time at the hospitals, he knows many doctors and I've loved every one he has recommended to me. His staff are very friendly & caring

Dr. Gresham has been my cardiologist for almost 2 years now. Based on his recommendation I had a pacemaker installed. He saved my life and gave me back a more normal lifestyle and a better all around quality of day to day living with full time work and family recreation. His bedside manner is excellent and he goes above and beyond to stay in touch and to gave me an explanation of how I am doing and what is going that I could easily understand. I would recommend him unequivocally to all.

I will not be recommending Dr. Gresham to anyone especially if a pacemaker is involved. I am very disappointed in the level of concern and consideration for situations unique to an individuals needs. I will be pursuing a doctor for my mother that shows some concern and is willing to try and accommodate the patient instead of the schedules of outside contractors. Considering the remote monitoring service provider has changed recently, I was expecting a little more attention to have been shown.

The admin got us an appointment right away. However, the Dr. never showed up. The staff knew the Dr. was not on site, but instead of letting us know - they just ignored us until we pressed the issue 45 minutes later. I understand emergencies, but communicate. Nurse told us PA was available and just as good as the Dr. and that the Dr. relied on the PA's opinion. Really??? No comfort there. Also, the Dr. shares an office with another Dr. and the other Dr.'s staff was very rude.
