Dr. Billesdon made me feel comfortable in the consulting room as well as just prior to the procedure, and EGD. When reviewing the results, he provided a clear printout, with color photos, which made it easier for me to understand the results. This certainly helps me stick to the new diet guidelines he recommended.

Dr. Billesdon has taken care of me for sometime, always professional and will answer any questions you have, he will also recommend what is good for you. I was infected with Hepatitus C and Dr. Billesdon and his staff have given me a new drug that in my last blood work shows I am not infected anymore. I highly recommend Dr. Billesdon and his staff.
