Why Should You Join CHOP Buddy Walk®?

CHOP Buddy Walk® celebrates all individuals with Down syndrome (also known as trisomy 21)! At Children’s Hospital of Philadelphia (CHOP), patients are cared for by our Trisomy 21 Program, an innovative, multidisciplinary program that began in 2002 to provide and coordinate care for children with this complex disorder. Our program is unique in that we care for patients with Down syndrome throughout their lives – not just during childhood. Our developmental pediatricians, therapists and researchers have made great strides expanding treatment and improving outcomes for these individuals. With the CHOP Buddy Walk® being the sole fundraiser for the Trisomy 21 Program, more funding is needed to continue our work.
