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!

Best of the Best
Overall good experience, thank you
I was originally scheduled to see another Dr., but because of his illness I was moved to see Dr. Marx. What a random blessing it was. Dr. Marx was very polite, listened, gave me the time I needed to ask questions and explained things clearly and concise. He was respectful of me and my treatment preferences all the while politely giving me the "typical physician recommendations". I was so impressed with his kindness, he might just be my new physician moving forward. It's hard to find physicians now a days who genuinely listen and care and explain and not push you. I never once felt rushed or did he ever indicate he had somewhere else to be. He was great.
