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.

Doctors are good. But the front desk is awful. All of the front desk members are so rude and have no brain. I will not go there again.

I took my mother to see him about an serious injury after an ER visit. The first thing he did was criticize her. He told her she was old and was going to fall again and she was going to die. I would have never believed it if I wasn't in the office. She was in a lot of immediate pain and instead of concentrating on the problem at hand, he decided to chastise her and put her down. While she may have some health issues to take care of, his manner of presenting his point was rude, disrespectful, and derogatory. It was horrible to the point of harassment. Not to mention he would not listen to her REAL problems. I will NEVER take her to him again.

I was under Dr. Freds care for a number of years and went in presenting of severe fatigue, muscle pain, depression and other awful things. I tried to kill myself because I felt so bad. Dr. Fred and his daughter just kept prescribing anti-depressants, baclofen, lower doses of synthroid. Come to find out, I had Hashimotos disease! If I had been diagnosed properly a few years ago, I would have not been having these horrific symptoms and my 16 year old would not have almost lost her parent.

this is worse experience anyone could have, this dr. invaited my privacy in front of his co workers and assistants. He did not care about my pain and all he was focused was to work for my employer not me. I was send to him by my employer and I did report him to work men comp and my employer. do not recommend him to anyone.
