In patients' words

"It is true that it is more difficult to get in touch with him since his practice was acquired by Yale. I don't believe this is any fault of his own, and despite that, I would never trust another doctor as much as I trust him."

Healthgrades - Dr. Mark Blitzer patient review

"waited almost an hour to see him and then he was more interested in showing off his knowledge to the intern who was shadowing him than talking with me."

Healthgrades - Dr. Jonathan Gage patient review

"He was very asuumptive about my weight. Pushed me to consider certain procedures without even discussing what I had tried. Continued to insist I try procedures even after I stated no firmly."
