After the Longwood Graduate Program, Mark started The Organic Mechanic Soil Company, LLC in 2006, and serves as President of Organic Mechanics. Mark has served as a consultant for the EPA and Institute for Local Self-Reliance.

Why ELA?

“I learn so much being a part of the ELA community! Between the conferences, newsletters, webinars, and networking with fellow ELA members, there is so much to explore within ELA. ELA’s commitment to educate and empower gardeners and landscape professionals is inspirational as we all strive to create practical and functional ecological landscapes.”
