I have had the same Doctor (Marx) for close to or over 20 years. He and his office have always been fantastic. I could not ask for better help...

I am a recovering addict who faces a lot of stigma when trying to receive medical attention. dr. Marx is the only doc I trust and feel like he acts out of kindness and love rather than stigma and judgement. I continue to see him even though I now leave close to 45 minutes away and feel very grateful to have him as my PMD.

Dr. Marx is fantastic - always takes time to talk about any questions, discuss my current health status, talk about family history and how it plays into my health needs, and he's just a genuinely great person who cares about his patients all around health and well being.
