Greg Mankowski - Compost Cordinator

Greg was raised in East Lansing and moved to Grand Rapids in the fall of 2014 to attend Aquinas College. He will graduate in May 2018 with a degree in Sustainable Business. For the last year, he has been composting in his backyard and making discoveries of the complex systems of micro and macro organisms interacting with one another. His noticing of a Your Compost sign this summer sparked his interest and lit a fire for a new passion. He applied to be a social media intern but at his interview he revealed his true desire to be a part of Urban Roots when he pulled out a bag of homemade compost! When he’s not tending to piles at Urban Roots, he enjoys disc golfing, listening to WYCE, and skateboarding.



Sydney Schulz - garden Education Coordinator

While beginning her pursuit of sustainability, Sydney became involved in land management work, environmental policy, and eventually urban agriculture.  She spent many years as an environmental educator and ecological steward and pursued conservation work across the country.  She has worked with tribes to restore native lands, national parks to preserve wilderness areas, and conservation groups to educate around environmental issues.  After an adventurous hiatus, Sydney is excited to jump back into urban agriculture in her native home of Grand Rapids, Michigan.  When she isn't growing food or leading outdoor expeditions, she spends her time exploring nature, teaching snowboarding, and honing her survival skills



Erin Williams - Community Market Associate

Itinerant by nature, Erin has hopped around from place to place throughout her life. She comes to West Michigan through schooling at Grand Valley State University, having earned a B.A. in Photography in 2016. Through work in restaurant management, Erin discovered a passion for food and a plant-based lifestyle. Erin came to Urban Roots in June of 2018 as Culinary Intern, getting to cook yummy meals made out of lots of plants for anyone who would try it. Erin officially joined the Urban Roots team as Community Market Associate for the September 6th grand re-opening, and is really excited for you to check out the sweet new digs. Stop in and say hello!


Nelly Jones - YOURCompost pedaller

Nelly has been involved in the Grand Rapids community since 2013, having moved here after graduating from GVSU. She has biked as her sole form of transportation since.  She spends most of her free time finding ways to create in herself ( and the community she lives in ) physical and emotional balance and harmony - constantly engaging in unique collaborations between like-minded individuals and organizations.  Nelly aspires to travel and connect with humans, blending mindfulness and play with all she does. Pedaling compost for Urban Roots has been a seamless transition, since she is an avid commuting cyclist and Shop Manager at The Spoke Folks nonprofit co-op.
