YFALS supports the ALS Therapy Development Institute (ALS TDI
the first and largest nonprofit biotech, dedicated to ALS research. ALS TDI was founded in 1999 by Jamie Heywood after his brother,
Stephen Heywood, was diagnosed with ALS at age 29. After finding no treatment options for his brother, Jamie realized that a gap existed
in the preclinical development of therapies for ALS. Jamie founded ALS TDI in the basement of his family's Newton, MA home in an effort
to bridge this gap and bring effective treatments to people with ALS as quickly as possible. Although Stephen is no longer with us,
ALS TDI continues to fight for young people with ALS today.
