Patient Comments (3)
I felt that he spent most of the time trying to me that I have Fibromyalagia, but by looking at the lab tests from nearly 2 years ago, I have no sign of RA or arthritis. The doctor that diagnosed both showed my husband and I the x-ray of my hands and where the RA is. It seemed to me the whole visit was to discredit the other doctor. I would have thought he would order new blood tests and x-rays, or MRI or something. Now I have to go to get a 3rd opinion. Wasted my time and money.

I am very pleased. After three months of treatment I have no inflammation. Dr.Oikonomopoulos is very straight forward, very knowledgeable, and has answered all the questions I have had. I am thankful to have found a doctor that actually cares and takes me seriously.

I had a very difficult time understanding this doctor as English is not his first language. I have some unusual symptoms that don't fit neatly into his computer program and his final remark to me was I guess you have just lived longer than your body was intended to I am 52!!! He spent most of the visit talking directly to his computer. I would not recommend him unless you have classic RA with the blood work to prove it. I am so upset that I spent money and time traveling for this visit
