"Before I was diagnosed with MS, I was given many false diagnoses. My symptoms began in 2004 and slowly worsened, intensifying over the years. It wasn’t until January of 2010 that I was finally sent for an MRI for the first time. During this time, I struggled with a variety of symptoms that were never adequately explained. After a year and a half of active MS, I was finally led to the IMSMP and my life once again began to return to normal. My doctor was able to get my pain under control which I never thought possible. He gave me the right treatments and medications along with physical therapy and he was able to put me into a remission, after such a long drawn out relapse. When I returned to him after 6 months of the treatments he had me on, he asked me to walk down the hallway, I told him I’d run and I did. I went from having babysitters around the clock, because I could not take care of my three children under four years old, to having an additional baby and now running after my 4 beautiful children daily! The gratitude I have for the IMSMP and to Dr. Williams is beyond words. They are always there when you need them. The office staff is helpful, the doctors are amazing, and the research team is determined to find a cure, which I believe will come from Tisch MSRCNY. They were able to get me out of a 16 month relapse and they have kept me stable. A few months ago I was dancing at a wedding in high heels and I had the biggest smile on my face. I said to my husband, thanks to Dr. Williams I can do this. I know with the help of the IMSMP, I can maintain this wonderful quality of life that they have given back to me and my family." - Melinda Saffioti
