Healthgrades review of Dr. Kanwar Gill

"My experience with Dr. Chin over the last 2 years has been horrible... he lied to me about what happened after a severe bleed... I would ask for explanations... he would down play it."

Healthgrades review of Dr. Matthew Chin

"I'm an old bird (77) with plenty of hospital miles on me and I want everyone to know how fantastic Dr. Gill, and John Muir Walnut Creek, and John Muir Concord are because many of us don't trust doctors or hospitals anymore. All A+++ here."
