Greenblatt is also famous for his contributions to education in New York City. In 2002, he donated $2.5 million to P.S. 65Q, a public elementary school in the borough of Queens, whose students come largely from the neighborhood's South American and South Asian immigrant communities. This investment, equal to about $1,000 per student per year over five years, helped P.S. 65Q to go from a struggling school to an urban success story almost overnight. 

He continues to aid the school in Ozone Park as they continue to rise. Recently the school and principal Rafael Morales received a progress report score of A, scoring 98 out of a possible 100 points.
