Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Dr. Villalon is my husband’s cardiologist. I also worked with him in the NorthBay ICU. I can’t begin to describe how kind and knowledgeable he is. He is a brilliant cardiologist and I am grateful for the wonderful care he always gives to my husband.

He is a punk! His staff at Northbay Vacaville will be harassing to patients and rude. The doctor them has the nerve to take his staff side when you stand up for yourself.

I miss Dr. Villalon something fierce. He is wonderful, caring, and trustworthy. He took great care to listen and truly cares about his patients. We need more like him. I'm incredibly sad to lose him as my cardiologist due to the distance of his new practice, but those that now get him are very fortunate!

Mark Villalon left the Napa Cardiology Group for a position in Solano County. He left the Napa Cardiology Group prior to them hiring another MD. I am now forced to wait to see a cardiologist. Very unhappy with this situation. Update: Villalon now works for North Bay Medical Group in Solano County. Same group that employs his wife. Recommend you find a doctor who will be there when you need one. I am very happy with the Napa Cardiology Group and will be staying. Very disappointed in Villalon leaving without a new MD in place.
