Christian Toebe
Project Director

Growing up, Christian pruned his green thumb in his family’s vegetable garden in Malvern, PA, a Philadelphia suburb. He also worked at local plant nurseries, as a handyman for a design firm, and on construction and electrician crews - all of which formed a solid platform for his future work as Project Director at Greensulate.

Christian studied Aeronautical Systems Maintenance Management at Embry-Riddle Aeronautical University in Florida. After pursuing a career in aviation maintenance management, Christian tapped into his Scandinavian roots - where green roofs have flourished for centuries - and began his career with Greensulate. A committed surfer, one of the many reasons Christian loves green roofs is their ability to keep local water ways and waves a lot cleaner.

Christian was one of the first 300 people in North America to get his GRP (Green Roof Professional) designation from Green Roofs for Healthy Cities, the trade organization for the green roof industry. The third Greensulator to join the company, Christian oversees all installations; he also educates clients and organizations about the myriad benefits of green roof systems.

His favorite green roof plants are Sedum hispanicum and Stachys byzantina (Lamb's ears). Email Christian.

He found the perfect platform to foster these goals by working with green roof systems in the vast metropolitan area of New York City.

Jamison holds a Business Management degree from Embry-Riddle University. Now living in Brooklyn, his combined experiences in business development, horticulture, and construction strengthen his role as Project Manager, which requires everything from designing to building both vegetative roofs and walls. Since 2009, Jamison has contributed to the installation of over 50,000 square feet of green roofs from coast to coast.

Jamison’s favorite green roof plant is Jovibarba Spp. "Beard of Jove.” Email Jamison.

Machias Schoen
Project Manager

Raised amidst the mountains, oceans, and rivers of Maine, Machias Schoen has always gravitated towards environmentally-minded pursuits. With a degree in environmental economics from Bates College, Machias has interned for the United States EPA, worked in adventure sports marketing as a property manager as well as for an aquaculture company on the coast of Maine.
