This was our first visit with this physician and his staff. It is hard to provide a full evaluation on meeting someone for 10-15 minutes or to say I would recommend him to others, That said, he appears competent, interested and skilled.

He was very attentive and listened carefully. He used words we understood. He didn't stop talking to use his computer. He was obviously smart and knew what he was talking about. We felt very relieved for a first time visit. Thank you

He was patient. He explained things over again when I was unsure of what it meant. He was descriptive on how the graft would work and what graft that I am eligible for. So that's it. Thank you.
