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.

Simply the best
I had Dr. S as my PCP for about a year. I changed to someone else only because I had moved away from Santa Clara. He is compassionate, patient, caring, experienced. He takes time to explain all your queries and concerns. I had not changed my PCP to someone else for a while even after moving, only because I was spoilt by how well he took care of me and quickly he responded. I was extremely sick and living alone for nearly 3 weeks during Christmas and New Year’s eve. He was responding to my emails, constantly checking my reports, prescribing medicines and kept checking back with me. It is not very easy to get to be on his PCP list. If you do manage to, you’ll be one of the lucky ones.

Dr. S is the most compassionate, caring, patient, attentive, and informative Doctor I have ever had the pleasure to meet. In all the years I have been Dr. S patient I have never felt “rushed” I don’t feel like what some people have stated “KP Cattle” never, not once. There have been times when I went to my appt. with a list of questions and he patiently answered all of them. He takes good Care of me and makes sure I am updated, and counsels me on what I am supposed to be doing for my health. I have many friends who work in various departments of Kaiser and they ALL same the same thing about this wonderful doctor. He is a medical angel to me. I wouldn’t trade him for another doctor if they paid me. In fact, if he was to leave KP many patients would follow him, I would be the first one. I hope KP values this wonderful employee which is a great asset to the medical field/KP. I am Blessed and honored to call Dr. S my Doctor.
