The Jewish Farm School is dedicated to teaching about contemporary food and environmental issues through innovative trainings and skill-based Jewish agricultural education.  


We are driven by traditions of using food and agriculture as tools for social justice and spiritual mindfulness. Through our programs, we address the injustices embedded in today’s mainstream food systems and work to create greater access to sustainably grown foods, produced from a consciousness of both ecological and social well being.


We ran our first program in 2006, sprouting out of a shared vision by our founders to develop educational programming that would foster opportunities for Jews to reconnect with the processes of working the land and growing food. Their vision consisted of establishing a school that would enroll students seeking alternative modes of education. In doing so, the learning would entail farming, animal husbandry, natural building and Jewish learning as well as achieve the necessary requirements for accreditation.

Since 2006, Jewish Farm School has run over fifty different programs, reaching over 7,500 children, college students, and adults. For three years JFS was named by Slingshot as one of the 50 most innovative organizations in North America, and our programs are a catalyst for lifelong learning and engagement in Jewish, environmental, and social justice-related issues.


Since 2013, JFS has been focusing our programs in the Philadelphia area that connect the local Jewish community with the vibrant urban agriculture and food justice movements. Click here to learn more about our current offerings.

Hannah Slipakoff

Kleinlife Garden Manager 


Hannah began learning how to grow vegetables as a teenager in Philadelphia, PA where the food justice and urban agriculture movement catalyzed her political and social consciousness. 


She is incredibly grateful to have experienced learning and working on diverse urban and rural farms over the past ten years; including apprenticing at George Jones Farm in Oberlin, OH, studying at The Center for Agroecology and Community Food Systems at UC Santa Cruz, training participants in The Philadelphia Community Farm Collaborative's Beginner Farmer Training Program, managing Mort Brooks Memorial Farm for Weaver's Way Food Co-op, and most recently, co-managing and supporting food sovereignty education programs for Soul Fire Farm in Grafton, NY.


Hannah works in awe of the innate human power to create, nurture, and sustain life. She balances her dedication to growing food with fierce commitment to practicing yoga, serving as a birth doula, and working with spirit in the kitchen. Hannah's role with JFS is to help manage the agricultural projects at KleinLife in Northeast Philly.

Alex Voynow

JOFEE Fellow


Alex grew up in the Pine Barrens, 45 minutes east of Philly, where his growing wonder of trees and forest soil mingled with a discomfort and distrust of mainstream suburban lifestyle, and set his eyes towards alternative and restorative ways of living. After graduating with a B.A. in Geography from Vassar College in 2015, he’s spent the past few years working in multiple nodes of the food system, including as a chocolate maker and a restaurant cook, and living on a variety of farms on the west coast and in Central America. He combines his love and understanding of food and agroecology with a commitment to social and ecological justice and community organizing, bolstered by his experience as a community organizer with the Stop Urban Shield Coalition and SURJ Bay Area. When not weaving together food justice, community organizing, and jewish tradition, you can probably find Alex in his kitchen, in a dance or yoga studio, or wandering the blocks of his neighborhood looking at trees and talking to neighbors and admiring West Philly’s infinite variety of porches.

Rowan Machalow

Side Yard Seedlings Program Manager


Some of Rowan's greatest loves are gardening, teaching, and Judaism, and they are excited to be leading a program that combines all three! Rowan is currently working on a doctorate at the UPenn Graduate School of Education, and has been an elementary and middle school teacher and preschool director. 


Rowan is a firm believer in supporting children in taking risks, getting dirty, following their passions, and making meaning of complex ideas. Some of Rowan's favorite teaching experiences with preschoolers put nature and Judaism at the center: taking care of chickens and collecting eggs, baking challah, caring for the garden throughout its seasons, making cheese and yogurt, dipping Shabbat candles, composting with a worm bin, and exploring the botanic origins of spices in a Havdalah besamim box. Through regular immersion in activities like this, Rowan believes that even city kids can build an intimate relationship with how the Earth provides and how we can nurture it.


Rowan lives with their partner and 4-year-old in West Philly. When Rowan isn't hanging out with JFS, they may be found playing guitar or viola, managing their synagogue's database, cooking and canning, serving on several boards, researching how teachers do their amazing work, and, of course, gardening.
