Miller & Long Employees Combined Retirement Plan

Miller & Long Employees Combined Retirement Plan

The Miller & Long Employees Combined Retirement Plan was established in 1989 to provide deferred-compensation benefits to the workforce of Miller & Long Co., Inc., a Bethesda-based concrete construction firm. The plan is not a family office or an externally marketed fund — it is a single-sponsor retirement pool whose assets are managed under a recordkeeping arrangement with Principal Financial Group. The sponsoring company remains owned and led by the McMahon family, with Brett McMahon serving as Chairman and CEO. As of 2019, the plan reported total assets of $68,903,808 (Altss estimate). It operates as a defined-contribution vehicle, meaning investment selection is participant-directed from a menu of options provided by the administrator. The underlying sponsor, Miller & Long, generates revenue through structural concrete construction across the Washington D.C. metro area and broader Mid-Atlantic region, including long-term project partnerships with firms such as Clark Construction Group. The company maintains significant operating assets — a commercial headquarters in Bethesda, a mixed-use property on Wahly Drive, and a fleet of construction equipment — though these are corporate-level assets and do not sit inside the retirement plan. Despite the plan's relatively modest size, the sponsoring company has deep regional roots and active industry affiliations, including memberships in Associated Builders and Contractors, the Washington Building Congress, and the American Society of Concrete Contractors. The McMahon and Pettit families, who control Miller & Long and historically guided the plan's oversight, also maintain separate philanthropic structures: the McMahon Family Endowment, the Pettit Family Charitable Foundation, and support for the DC Students Construction Trades Foundation. No verifiable operational event in the last 24 months was identified for the plan itself. Structurally, the Miller & Long Employees Combined Retirement Plan sits at the intersection of a privately held construction enterprise and an ERISA-governed benefit pool. Unlike institutional allocators that function as limited partners in venture and private equity funds, this plan is an employee-benefit vehicle whose investment posture is defined by the recordkeeping platform rather than a discretionary internal investment committee. The key distinction is one of mandate — it exists to serve the retirement needs of several hundred skilled-trades employees, not to deploy capital into third-party alternative funds.
