Welcome from the CEO of MDA

Sharon Hesterlee, PhD, President and CEO.

Dear Friends,

Welcome to the Muscular Dystrophy Association (MDA). We are honored to be featured as the inaugural organization in Rare Disease Advisor’s Rare Advocacy Spotlight during our 75th anniversary year.

For 75 years, MDA has advanced research, expanded access to expert care, and strengthened the community that connects families, clinicians, scientists, and partners across the rare disease landscape.

On MDA.org you’ll find trusted resources, from clinical updates and patient support to our Care Center Network and the annual Clinical & Scientific Conference. We hope this is the first of many visits, and that you find the knowledge, connection, and inspiration you need here.

On behalf of everyone at MDA, thank you for visiting. We look forward to the future we will build together.
