Jackie Mueller

Jackie was diagnosed with Relapsing Remitting Multiple Sclerosis in 1998. She left the doctor’s office that day determined to do what she could to fight the disease. With the help of her husband and the support of family and friends, she made the decision to combat the diagnosis with some lifestyle changes. As she was doing research, she stumbled upon the MS Fitness Challenge website and was encouraged by the work they were doing to promote exercise as an alternative in battling MS. After sharing the information with her husband, Mark, they both recognized immediately the benefits a Challenge would have for anyone in the MS community. A part of Jackie’s heart and passion behind joining the MS Fitness Challenge team is to honor her mom, who lost her battle with the disease a few years ago. It is her desire to bring the MS Fitness Challenge to as many people as possible that suffer with MS, giving them exercise tools that can help improve the quality of their day to day life.

Jackie Mueller, along with her husband, Mark who is the Director of Trainers for MSFC, own and operate Mueller Personal Training in Elizabethtown, PA. Together, they have three children, Jessica (Aaron Fellenger), Mark (Casey) and Sara, one granddaughter, three grandsons and a dog named Happy.


Mark Mueller

"I believe that people are brought together for a reason. Great things are about to happen as we diligently work on making a difference for people who deal with MS every day. Together, we are going to reach as many people as we possibly can to help them understand how nutrition and exercise can benefit them by enhancing the quality of their lives."

Mark Mueller is the Director of Fitness & Trainers for MSFC. He has a BS in Psychology and has achieved Elite Trainer status through ISSA (International Sports Sciences Association). He is a certified Fitness Trainer, Specialist in Fitness Nutrition and Specialist in Exercise Therapy as well as an MS Fitness and Wellness Specialist. Mark has been involved in some aspect of fitness his entire life, but because of his love for it and his desire to share it with others, in 2012 he made it his full-time profession. Mark spends much of his day in the gym personally training clients and then goes to work creating, developing and hosting community wellness events. He has been responsible for setting up personal training programs in local gyms and in a physical therapy clinic to help rehabilitation patients further their progress. He has studied the martial arts under the "A" Kido Karate Association International (American Kido) and is a black belt and previous instructor. Mark has personally dealt with MS for over twenty years as his mother-in-law developed the disease in 1993 and his wife, Jackie, was diagnosed in 1998. Mark was instrumental in working with American Fitness Professionals and Associates (AFPA) to develop the MS Fitness and Wellness Specialist certification course for trainers and fitness professionals. His desire is to help as many as possible with his knowledge from his formal education and that which he has gleaned from his practical experience.
