Yardmaster, a commercial grounds management platform backed by private equity firm Unity Partners LP, has completed the acquisitions of Ann Arbor, Mich.-based Twin Oaks Landscape and Marion, Ohio-based ProScape Lawn & Landscape Services.

Twin Oaks, founded in 2001, provides full-service lawn and landscape maintenance to commercial and residential properties in southeast Michigan. ProScape, which Luke Henry founded in 2005, offers commercial grounds management to HOAs, multi-family properties, warehouses, retail centers, healthcare facilities, schools and office properties across central Ohio. The deals add more than 100 teammates to the platform and increase density in central Ohio and southeast Michigan.

“We are excited to welcome the teams from Twin Oaks and ProScape to the Yardmaster family,” says Mike Montenaro, CEO of Yardmaster. “Both companies have earned outstanding reputations for customer service and the quality of work they have delivered to customers.”

Chris Speen, founder of Twin Oaks, says the opportunity for employees to become owners through the Employee Purpose Plan made Yardmaster “the right home for our team.” Henry adds, “Yardmaster shares that same commitment to putting people first, which is why this partnership is the right one for us.”

Unity Partners invested in Yardmaster in November 2025. The company says it will continue pursuing strategic acquisitions across the Midwest.
