Marge is great!!! I went to her with back problems. She listened to me and my body. She was very intuitive, patient, gentle, understanding, and knowledgeable. She told me when to expect to feel better, and she was right. She didn’t push another appointment. She told me to listen to my body and come in when I thought I needed to.

I eventually brought my 11-year-old daughter in to see her. She did the same with her. She made her feel comfortable. She was calm and clear about what was going on. She set perfect expectations for her recovery.

It was easy to schedule an appointment. I HIGHLY recommend her!!!! – s B. (Herndon, VA)


I don’t know what her secret is, but she has “it”.  I found her online and went to her for pain and discomfort I was experiencing in my neck and shoulders for about 6 months straight.  I had already been to my chiropractor, my regular doctor ( prescribed muscle relaxants, which just dulled the pain, etc…)

I had my initial visit with her and explained my condition and background, and she did she showed me some stretches and movements to help loosen up and also did some “laying of the hands” and what I can only explain as energy movement and therapy, and then scheduled a second visit.

The morning of the second day after my initial visit, the pain was GONE.  Totally gone. I’ve been back to see her for several follow up appointments, but I’ve already got my wife going to her as well.  

What else is there to say?  She is good at what she does! – Nader G. (Vienna, VA)
