I believe that team based collaborative care is the key to helping patients achieve their health goals. To that end, I strive to tailor my advice to each individual, involving patients in their health care decisions. We then employ a team approach to support those goals. My office staff, medical assistants, nurses, care coordinators, advanced practice partners act as a willing and eager cast to help patients succeed. Come see what a team approach can do for your health!


Dr. Marx serves in a leadership role as a Regional Medical Officer within F&MCW Community Physicians.  He is partnered with Monica Braun, NP sharing a robust and dynamic practice.  With over 15 years of experience he is positioned to care for you and your family in a patient centered fashion.

Dr Marx is a new physician in the last three months for me. I have seen him twice and a nurse practitioner once. His care was excellent. He referred me to two specials who helped support and improve some long term issues I was dealing with. The communication, follow up calls, use of MyChart have already improved my health

Oct. 16, 2019
I n the past Dr. Marx was available any day of the week but now when I call his availability is limited to only a few days a week. And I have to see a different Dr. The replacement is just as courteous and professional but I would rather see the Dr that I have been with for the last 20+ years.

I love my doctors and our pediatrician, but it is becoming increasingly difficult to get a same day urgent care appointment with anyone. I am willing to see other docs and/or PA or a NP, but rarely can get in with them, either. We are often referred to the walk in clinic, especially for peds issues.
