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.

Very professional and easy to talk to. Saw physical things that I hadn’t even noticed. Love that he actually saw me vs an object or computer.

Dr. Ontanillas is a pleasant person with a reassuring demeanor. If you are a relatively healthy person who likes to have nice, sociable doctor visits with a minimum of follow-up, he might be right for you. Unfortunately, if you have chronic conditions that need monitoring or if you have a more complicated health history, he is not thorough, interested, or diligent enough to be of service.

Dr. Ontanillas is compassionate and professional, but very straightforward. If he doesn't know about something, he takes the time to research it instead of bullshitting you and playing it off like he knows everything. I think he's a wonderful doctor, and I'm better off for his care.
