Our office at 3030 12th Street NE is a renovated building which we enlarged to accommodate an expanding number of staff, classes and workshops. The site boasts a bioretention planter, three green roofs and a white roof. These “green” features qualified our headquarters to participate in the Sustainable Sites Initiative (SITES) Pilot Program.

Casey Tree Farm

Casey Trees also owns and operates a tree nursery in Berryville, VA - allowing us to grow tree species that are not readily available commercially while employing innovative growing and irrigating techniques.
