What Mattson Macdonald Young does

Mattson Macdonald Young (MMY) is a Minnesota-based structural engineering firm founded in 1983 that provides design and consulting services for new construction, renovations, and specialty structural applications across residential, commercial, institutional, and public-sector projects. The firm operates with 10 licensed professional engineers and 2 engineering technicians, delivering project-based professional services that range from single beam design for homeowners to $50 million rehabilitations of historic and institutional buildings. Core capabilities include structural design using AutoCAD and Revit Structure, with specialized practices in historic renovation (including familiarity with the Secretary of the Interior's Standards for the Treatment of Historic Properties), cold-formed steel design, suspended maintenance and fall arrest systems, public art and sculpture structures, renewable energy support structures, and connection/equipment design for steel fabricators.

The firm serves architects, building owners, contractors, and government entities primarily across the upper Midwest, with engineers licensed in Minnesota, North Dakota, South Dakota, Wisconsin, and Iowa plus additional states. Customer segments span commercial buildings, multi-family and single-family residential, public and government facilities, historic preservation projects, healthcare, education, churches, industrial, and parks and recreation. Revenue is generated through project-based professional services fees on a custom quote basis, with no pricing publicly disclosed. Marketing is conducted primarily through an award-laden project portfolio and referral-based relationships cultivated over four decades in the regional architecture and construction ecosystem.

As of 2025, MMY has been acquired by and is now operating as part of Sandman Structural Engineers, with the Minneapolis-area team based out of Sandman's Maple Grove office. The firm maintains its brand identity and client relationships while gaining access to expanded resources and collaboration across the broader Sandman platform. No venture capital or private equity investment is associated with the firm, and ownership was historically held by a partner group including Stephanie Young, David Macdonald, Joseph Cain, Ken Green, David Hedberg, and Matthew Hogen.
