Mitchell, a prep standout in Connecticut who plays for the Utah Jazz, attended a ribbon-cutting at The Children's Village in Dobbs Ferry, where his grandmother worked, said ESPN writer Nick DePaula.
DePaula tweeted that the family made the donation as part of Mitchell's DON 3 shoe launch with Adidas.
Mitchell attended Canterbury School in New Milford, in Litchfield County, Connecticut, and Greenwich Country Day School in Fairfield County.
