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.
