What Hamilton Stern Construction does

Hamilton Stern Construction LLC is a privately held, full-service commercial construction management and general contracting firm headquartered in Pittsford, New York. Founded in 2010 by Justin Hamilton and Chris Stern from a single bathroom renovation, the firm has scaled to 60–70 employees and now delivers projects across 15 New York State counties. It serves enterprise and institutional clients in commercial, education (K-12 and higher education), industrial/manufacturing, multi-family and affordable housing, healthcare/senior care, nonprofit, and historic preservation markets, with named clients including St. John Fisher University, Ibero-American Development Corp, Foodlink, Hurlbut Care Communities, ESL Federal Credit Union, and the YWCA of Rochester & Monroe County.

The firm's service portfolio spans four delivery methods — preconstruction (estimating, value engineering, constructability analysis, scheduling, guaranteed maximum pricing), design-build, construction management, and general contracting — executed through direct client relationships, RFP responses, and developer partnerships. Notable technical credentials include delivering the first PHIUS Core-certified project in Rochester's Downtown Revitalization Initiative (Alta Vista at St. Joseph's Park), the AGC NYS 2025 Build NY Award-winning $42 million Lavery Library modernization at St. John Fisher University, and historic preservation work recognized by the Preservation League of New York State. No AI/ML, software-as-a-service, or proprietary technology platform was identified in the source data.

Revenue is generated through professional-services project contracts and is not publicly disclosed. The company is founder-led by Hamilton and Stern alongside President Jason Van Zeilen, with a Chief Operating Officer (John Ilijevski) added in February 2026 to support organizational scaling, and has no parent company, private equity backing, or institutional investment identified in the input.
