Greatland Realty Partners

What Greatland Realty Partners does

Greatland Realty Partners is a privately held commercial real estate developer founded in 2018 by Kevin Sheehan and Phil Dorman, both formerly of Boston Properties. Headquartered at One Federal St., 28th Floor, Boston, the firm acquires, develops, owns, manages, and leases commercial properties concentrated in Greater Boston's Route 128 West corridor, with an emphasis on suburban office-to-life-science-lab conversion.

The company's portfolio spans seven assets and over two million square feet, valued at approximately $1.5 billion. Properties include Revolution Labs, Riverside Labs, Hartwell Labs, CambridgePort Labs, Lexington Labs, the Campus at Marlborough, and 275 Grove Street (Riverside Center), with an additional 200,000 SF ground-up development of the Mass State Police Crime Lab under construction in Marlborough. Tenants include enterprise clients in life sciences, healthcare, and technology such as Siemens, TechTarget, Thermo Fisher Scientific, Hologic, Parexel, Atrius Health, and Braskem, alongside government occupiers.

The business generates revenue through long-term commercial leases across industrial, office, and lab segments, supplemented by capital appreciation on owned real estate and capital markets activity (e.g., the $50.5M CambridgePort Labs refinancing). The firm operates a relationship-driven go-to-market via exclusive leasing arrangements with institutional brokerage firms including Colliers, CBRE, JLL, and Newmark, and maintains a strategic capital partnership with Barings (a MassMutual subsidiary managing $360B+ in assets) that enabled the $117.5M acquisition of 275 Grove Street from Alexandria Real Estate Equities.
