About
Eric Geisberger is owner and operator of RG Tree Service, the Menomonee Falls tree-care company whose initials honor founder Rick Garvens.
Garvens spent twenty-four years as a Milwaukee city forester while building the side business in his hometown; he later brought Geisberger aboard at age seventeen and mentored him into a certified arborist before passing the torch.
Geisberger frames the firm as a passion business rather than a franchise—pairing his own arborist credentials with foreman Chris Dubey, another certified arborist with more than two decades in the trade. The company markets pruning, removals, and stump grinding across Menomonee Falls and neighboring communities, citing fifty-plus years of combined legacy experience and thousands of customers served.
RG Tree keeps a main office presence in Sussex while remaining rooted in Menomonee Falls. Under Geisberger the brand stays a local, owner-operated arborist shop along the Falls–Sussex corridor.
