Since 2001, Jett Foundation has met the needs of the Duchenne muscular dystrophy community. While we were founded out of one family’s desperate need to save their son, we have transformed dramatically. Once a non-profit dedicated to raising money for biomedical research, today we are meeting our families and young people where they are with direct service and educational programs that improve and enrich the lives of individuals impacted by Duchenne.

We empower patients and families with the knowledge needed to be their own best advocates, spread awareness about Duchenne, and help accelerate research and development. We believe for Duchenne patients, education equals survival. Please use this sheet only as an outline when learning about potiential options for you, your child, or your patient.
