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 Hahn is extremely talented, kind and patient.
Dr Hahn understands so much about the brain and how it works. But he really cares about the person and who you are. He had helped me with so much. He has been a constant advocate for me.

×Post a ResponseAre you Dr. Hahn?
Dr.Hahn literally saved my life. After years of different psychiatrists, no one is as talented and experienced as Dr.Hahn. I have exceptionally bizarre reactions to medications but Dr.Hahn took them all seriously and was able to explain my brain chemistry and why things were happening and then created a medication regimen that worked for me. I've never had a better doctor and I cannot recommend Dr.Hahn enough.

I’ve seen a lot of doctors throughout my life and Dr. Hahn is the best I’ve ever come across. He listens, makes you feel comfortable sharing symptoms, and he’s just a really nice guy.
