Stephen Ritz is South Bronx educator and innovator who believes that students shouldn’t have to leave their community to live, learn, and earn in a better one. While moving generations of students into spheres of extraordinary personal and academic successes, Stephen’s extended student and community family have grown more than 65,000 pounds of vegetables in an effort to reclaim and rebuild the Bronx. 

Stephen helped earn his school the first ever Citywide Award of Excellence from the NYC Strategic Alliance for Health and directly attributes these results to growing vegetables in school. To take ownership of his own health and model good behavior for his students, he lost more than 100 pounds by eating what he and his students grow. In 2013 The United States Department of State and New York Foreign Press Corps toured representatives from 40 countries across Stephen’s worksites and classrooms. He was selected as a delegate at WISE (World Innovation Summit for Education) and as a national Green Apple Education Ambassador for the US Green Building Council and Center for Green Schools. In 2014, Green Bronx Machine celebrated a Best of Green Schools Award — one of only ten recipients across the United States and The National Association of Secondary School Principals cited Stephen’s work and Green Bronx Machine as one of five national exemplars of service learning.

That same year, Stephen’s fourth and fifth grade students accepted a personal invitation from White House Chef William Yosses to visit the White House and exchange ideas about food literacy. Consequently, Stephen and his students began hosting Chef Yosses in the Bronx on a regular basis. Stephen’s Bronx classroom featured the first indoor edible wall in NYC DOE, which routinely generated enough produce to provide healthy meals to 450 students while training the youngest nationally certified workforce in America.

His students have embarked on growing projects from Boston to Rockefeller Center to the Hamptons and beyond — all while earning living wages en route to graduation. In 2015, Stephen was named a Top 10 Finalist for the prestigious $1m Global Teacher Prize. 

Affectionately known as "America's Favorite Teacher," Stephen has moved daily attendance from 40% to 93%, reduced behavioral incidents, improved test scores and helped create 2,200 youth jobs in the Bronx. Consequently, he captured the United States EPA Award for transforming mindsets and landscapes in NYC.

In 2016, on top of his frequent speaking events (some of which included audiences topping 10,000 attendees) and daily school responsibilities, Stephen worked to develop a ground breaking, internationally certified curriculum which embeds concepts of sustainability, food, energy and environmental justice aligned to STEM content areas for elementary schools. Stephen and Green Bronx Machine also brought to life the first ever independently financed National Health, Wellness and Learning Center in a 100+ year-old, abandoned school library at CS55 in the South Bronx. Soon thereafter, he partnered with LoyaltyOne in Canada to launch "The Good Food Machine" in 10 elementary schools, modeled after his programs in NYC.  The U.S. Botanic Garden in Washington, D.C. erected a model of his classroom as an example of successful urban agricultural integration into academia. He presented twice at The White House — once for the “State of STEM” event and again for the first annual South by South Lawn event. He also signed a book deal with lauded health publisher, Rodale Publishing. Released on May 2, 2017, The Power of a Plant, debuted as a #1 Best Seller on Amazon with endorsements from KIND Founder Daniel Lubetsky, Author Deepak Chopra, Author Marion Nestle, Chef Tom Colicchio and many more. 

In 2018, Stephen partnered with Chicago Blackhawks captain, Jonathan Toews, to replicate his school model into 20 Chicago Public Schools.  Additionally, he was named Director of Health, Wellness and Innovation for ESOL Education, the largest provider of American International Schools in the world. Stephen will soon begin building the second National Health Wellness and Learning Center at The Sustainable City in Dubai — the first net positive, solar powered city in the world!

To date, Stephen’s work has been featured in Forbes, Fast Company, New York Times, Wall Street Journal, USA Today, and on ABC, NBC, CBS, CNN, FOX, TNT, Disney, and NPR, as well as internationally from Colombia to Dubai. His TED talk boasts more than 1 million views, he was featured in the film adaptation of Michael Pollan’s best-selling book, In Defense of Food, NPR’s All Things Considered, ABC’s The Chew and The Rockefeller Foundation’s Food for Thought. Heroes in the Classroom featured Stephen as one of the top fifty teachers in America. In 2017, Stephen filmed an episode of Growing a Greener World, which won the series its first Emmy Award in over 100 episodes.
