Patient Comments (6)
Dr. Thomas failed to help manage liver disease patient after diagnosis and keep up with patient progress. When times turned worse, Dr. Thomas was no where to be found. He dropped the ball when a hernia formed from the liver disease. Patient is no longer with us after six months of fighting liver disease because Dr. Thomas failed at the one thing he has a degree in. As others have said, you see his staff more than you see him. Shame he has a job.

First experience having a colonoscopy with Dr Thomas While I spent very little time with him, I'm very satisfied with my experience
in Canandaigua, NY |
Do Not call if you have an infection on or near your stoma. I tried and was told they could not get me in for over three weeks, to go to my primary or ER. They claim their goal is to provide a high standard of care, but I think not. I did like this doctor years ago, but now they don't seem to have time. I found out I was in fact infected, put on antibiotics, and will now need to travel to Rochester General to be evaluated for surgery. DO NOT CALL IF YOU THINK OR KNOW YOU HAVE AN INFECTION.

I did not meet Dr Thomas until the procedure (upper endoscopy), instead I saw his assistant, who I was scheduled to see post procedure too. The doctor spoke to me from across the room, asked why I was there, did not speak to me at all throughout the procedure, and afterward handed me a skimpy pamphlet on GERD and explained very little, told me to increase my meds but did not phone in a prescription. Results of lab tests were up to me to find for myself on the patient portal but were not there

The doctor ran serious of tests on me and when the time has come to discuss the results he did not even come sending PA to talk to me. I find it completely unprofessional and careless. Very disappointed.
