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.

My 16 year old daughter was terribly misdiagnosed and heavily prescribed mood stabilizers that she didn’t need and which worsened her mental health and caused 80lb+ weight gain. It took many months to get her off of all of his medications, none of which she needed. Shame on you John Mariani. Do no harm? I think not.

×Post a ResponseAre you Dr. Mariani?
I went to him for depression and anxiety issues, trauma. He gave me therapy as well as part of session. . He misdiagnosed me more than once , giving me incorrect medication and in turn I wasted years of my in pain when I didn’t have to, and money. I finally found someone who was more qualified to be a psychiatrist and am on a better place, I do Not recommend him, at all.
