Trimark Corporation was formed in 2001 through a merger of two smaller commercial real estate companies, building on predecessor businesses that had provided property management and related services in Virginia, Maryland, and Washington, D.C. since the late 1960s and mid-1980s. Trimark Corporation focuses on property management, property accounting, facility maintenance, leasing, and project management for commercial real estate properties. The company serves a broad mix of office and medical buildings, retail centers, mixed-use properties, urban residential condominiums, flex and warehouse properties, and property owner associations across the Mid-Atlantic region. Trimark Corporation also emphasizes responsive management, financial reporting, and day-to-day operations support for commercial and residential property owners.
