We welcome you to our vibrant and passionate ALS community. Join us in our fight against ALS.
In 1999, James Allen Heywood founded the ALS Therapy Development Institute (ALS TDI) to find a cure for his brother, Stephen. Today, we continue to be led by people living with ALS, their families, and communities who understand the urgent need to slow and stop this disease. Your support helps advance promising treatments at the world’s foremost drug discovery center focused solely on ALS. We are committed to working closely with people living with ALS, their family and friends, and connecting them to each other to share information and experience.
