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
When I was 16 I told Dr Williams I was trans and he told me I was lying. I’m 29 and and living as a trans woman. Dr Williams caused me some much hurt and pain, I still shudder to this day. Truly please avoid.

My son was being emotionaly mistreated by his father. He was suicidal. It would have been easy for Williams to not report the man for his behavior but he had the courage to do so despite the man’s threats. Williams got the state involved, and I am really thankful for that.

Stay away from this guy, he rushed his decision to hospitalize my daughter and the whole experience was appalling. He gave us, her parents, literally no information, refused to speak with me, her father, and cowered behind his email. If you want your loved ones to be treated like cattle, then Williams is your guy, if you're looking for someone who applies logic to his decisions, go elsewhere.

Dr. Williams successfully treated our daughter over a period of six years, from age 7 to age 13.. Can't say enough good things about him. We went every three months from 2011-2017. Our daughter suffered from autism, ADD, OCD and hyperactivity. She was aggressive and difficult. Not anymore. Very grateful for Dr. Williams's intelligence, cautious approach with medication, and ongoing excellent care. Please note that we fired the two psychiatrists we tried before we found him. Highly recommend

I came to Dr. Williams on a number of medications that weren't working for me and in the worst state ever. Dr. Williams strategically did research on my family medical history, listened to my experiences and tested me with theGenomind Genecept Assay.He figured out what I needed and helped wean me off of multiple failing medications..Under his care I regained a will to live through Cognitive Behavioral Therapy and grounding skills. I am ever-greateful for Dr. Williams. I recommend him highly

Happy Patient in Main Line PA – Nov 14, 2017
×Post a ResponseAre you Dr. Williams Jr?
Dr. John Williams has thoughtfully and professionally cared for every member of my family whenever the need has arisen.Some have been brief and simple issues, while others have required more complicated and lengthy therapeutic solutions. Finding a physician who is skilled in proper diagnoses, careful medication management, AND individually focused therapy is not an easy task. Every patient and each of their needs is viewed through a personalized lens, while never losing sight of the family.

Dr John Williams is a professional and very knowledgeable doctor. He works with you to get a diagnosis and gives you a complete and helpful treatment plan. He helped me overcome several traumatic events in a safe environment with guidance on how to handle difficult situations.
