Green Bronx Machine serving more than 50,000 students around the world every day

We grow vegetables…
and our vegetables grow students, schools, and communities!

Green Bronx Machine is an impact driven, for-purpose organization with 501(c)(3) status rooted in the belief that we are all Amer-I-Cans! Green Bronx Machine was born via collaboration between life-long educator Stephen Ritz and his students who observed that as waistlines expanded, engagement and opportunities in school decreased, school performance suffered, and hope and ambition became minimized. Originally an after-school, alternative program for high school students, Green Bronx Machine has evolved into K-12+ model fully integrated into core curriculum. Our students grow, eat and love their vegetables en route to spectacular academic performance.
