About
Rooted in Ann Arbor since 2011.
Nora was designing gardens that nobody looked after. Owen was running crews that never saw the design. In 2011 they started Sumac to do both, and added snow two winters later because clients asked who’d clear the drive.
Today 26 of us work through the season and 14 through the winter, for about 400 maintenance clients and 60 design-build projects a year. The yard on Industrial Highway is where the trucks, the stone and the mulch live. The same crew leads have been here for most of that time.
