L & M originated in 1986 as a small landscape company in the Upper Valley. “L” for Larry, and “M” for Maureen, they began their business with a handful of clients and a wheelhorse mower. In 1999 they purchased the former H.B. Biathrow Construction Company, that dated back to the 1950s, establishing L & M Service Contractors, LLC. In 2013 Larry and Maureen sold the company to their son, Ryan.
Ryan’s ambition has grown the company into a leader in commercial contracting services for many of the Upper Valley’s top employers.
