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.

The staff at Germantown Clinic is very good..Dr Marks is a outstanding Doctor . You are lucky to have him..

Dr. Marx has been my physician for 15 years. He is kind, compassionate and has extremely good listening skills. He asks questions to clarify what I have told him and always, always greets me and leaves with a smile and a handshake. I cannot express how much I respect him as a doctor and a human being. He saved my life on my first visit and continues to work with me and for me when needed. I recommend him to anyone looking for a physician. I wish more of your doctors were like Dr. Marx.
