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.

Our bioretention planter collects and absorbs stormwater runoff from nearby paved surfaces like streets and sidewalks

Our green roofs.
