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.

Terrible experience - waste of time and money
I had an awful experience with Dr. Rosales. I had to wait in office for my appointment for over 2 hours, just to receive poor bedside manner, too close of contact, and no answers. Overall, I was at this office for over 4 hours and left after most of the staff. It has been 2 months and I am yet to get any results from tests. Additionally, I had a telehealth appointment that he simply didn't show up for. I attempted to call the office multiple times and didn't get a response.

I know Dr. Rosales as a doctor and as a person, because I spend many years working close to him and his patients. He's not only a great human being, but also a great physician. He's very gentle, knowledgeable, his bed side manners are impeccable, he's compassionate and his patience is way above and beyond expectations. He is my husband's and other family and friends physician, (and believe me when I say that I'm very "choosy" when selecting physicians to my family). He have my total confidence

Dr. Rosales is a brilliant cardiologist, but more important is how he treats his patients, Calm, quiet and gentle, he patiently listened to everything I had to say. He explained my condition in understandable terms and left plenty of time for questions. He was thorough without ordering unnecessary tests. He truly is one of a kind!
