Jacob Sloane, M.D., Ph.D. is a neurologist at the Multiple Sclerosis clinic at Beth Israel Deaconess Medical Center in Boston, working to enhance the high level care of Multiple Sclerosis patients at this institution and to conduct Multiple Sclerosis related research.

David Lyons was a healthy bodybuilder and gym owner when he was diagnosed with multiple sclerosis in 2006 at the age of 47. The doctors told him he would rapidly decline and require a wheelchair. Instead David battled the disease in the gym and challenged himself by competing in an NPC bodybuilding competition.

David and his wife Kendra then founded the MS Fitness Challenge, which provides certified fitness professionals to people with MS nationwide for 12 weeks at no cost as well as a gym membership, in an effort to educate and train them in the benefits of exercise and nutrition.

With American Fitness Professionals & Associates (AFPA), David developed the MS Fitness & Wellness Specialist certification, and he currently writes for EverydayHealth.com. He and Kendra have also launched their own gym, the OptimalBody Personal Fitness facility in Murrieta, CA.
