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. Alonzo does an excellent job. He really cares about his patients and listens to their situations. He is very responsive and experienced. After assessing the situation he takes prompt action to treat the conditions. I highly recommend him.

Just signed up for Medicare and choose Dr. Joseph Alonso as my primary doctor. Set an appointment with his staff for three weeks away. The day of my appointment I show up and am told that Dr Alonso is not in today. They did not explain why I was not called but apologized and set up a telephone appointment three days later. Dr. Alonso never called me for my telephone appointment either. Stood up twice with no call. I called their office and a recording said someone would be right with me. I waited 8 minutes and then later called and waited 20 minutes without any answer.

MD Alonzo is the best. He takes the time to make sure he understands your health issues. He also offers alternative treatments as medicine is not always the answer. MD Alonzo has many years of experience and is not stuck on old style treatment and is always positive about new ideas
