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.

Great Doctor
I have been going to Dr. Diaz for over ten years. Not only is he a very good Doctor that has helped me immensely, but he is also a good person. I think his staff is also very good at their jobs and have always been nice and personable. If you are looking for a place that will care for and about you... there is no place better.

Dr. Diaz and the front desk staff have always been great! He has found medical issues that others doctors have missed and he is a great listener. The front desk staff have always been kind, receptive and do what they can to get me a quick appointment. I’ve been going to him for almost five years, have no complaints, and have recommended him to others.

Dr. Diaz has been our family physician now for over 20 years. He's the best doctor I know. Always takes the time, always listens to you, always knows what is going on with you, provides the medication and/or necessary corrective action needed, and directs you on how to take better care of yourself. Absolutely love this doctor.

I have no idea what these people saying I’ve been seeing doctor Diaz for over 20 years I’ve never had a problem with anyone in the office my husband and I have always been treated amazingly . Dr Diaz is a wonderful doctor and he has saved my life 2 times by thinking fast on his feet I had a massive Cist he found it then I had a bowel obstruction and doctor Diaz knew right away by my symptoms if he had not told me to get to the hospital immediately I could have died . He is very kind .

Dr. Diaz is great. Rest of the practice is almost always friendly and professional. Have had a problem or two scheduling, and haven't loved every phone interaction. Nothing is perfect, but I hope they'll work on this because I really do like them, and I wouldn't hesitate to recommend them..

Dr. Diaz is an awesome family doctor who treats the patient rather than the symptom. He is a good listener. He has great staff and a caring practice.

I've been a patient of Dr. Diaz for five years. He explains & answers questions. All Dr. referrals I have received have been excellent. Dr. Diaz believes in keeping his patients healthy! He expects is patients to care about themselves! Exercise & eat healthy. One of the best Doctors I've encountered. He cares.

Does no one treat their patients like people instead of numbers anymore? The receptionist, Jenny was very unprofessional, like she just wanted to get rid of my wife without listening to her problem, then taking the appropriate course of action. David was only willing to consider his employee’s story, without gathering all of the facts, before having an informed and empathetic discussion. He wrote off my wife's concerns, finally telling her to look for another doctor. Again, very unprofessional.
