What Mulhern & Kulp does

Mulhern & Kulp (M+K) is a U.S. structural engineering firm founded in 2000 by Michael Mulhern and Joseph Kulp, headquartered in Ambler, Pennsylvania. The firm specializes exclusively in residential structural engineering, with deep expertise in wood-framed construction across single-family production homes, custom homes, coastal homes, townhomes, multi-family apartments and condominiums, mixed-use developments, senior living facilities, and select light-commercial projects. Its core services span the full project lifecycle — construction documents (prepared in AutoCAD and REVIT), construction administration, wind design, I-joist layouts, and existing-building/renovation engineering — with SAPPHIRE software used to automatically generate lot-specific structural plans for production-builder clients. The firm is licensed to practice in all 50 states and operates from four regional offices (Philadelphia, Atlanta/Alpharetta, San Diego, Boston), employing roughly 130 people, including 74 engineers, 12 technicians, 11 project managers, 5 principals, and 7 interns as of 2024.

The firm runs a project-based professional services model, billing clients for engineering deliverables on a per-project basis with no publicly disclosed pricing. Its go-to-market is direct, relationship-driven enterprise field sales to architects, builders, and developers, supplemented by word-of-mouth referrals and a professional website. Named enterprise customers include several of the largest U.S. production homebuilders — Lennar, Pulte Homes, K Hovnanian, Meritage Homes, Drees Homes, David Weekley Homes, and Stanley Martin Homes — alongside mid-market regional developers and architectural firms such as Minno & Wasko, Asher Slaunwhite Architects, and Niles Bolton Associates. In 2024 the firm completed 2,407 projects for approximately 220 active customers across 116 markets.

M+K has remained founder-owned and bootstrapped throughout its 25-year history, with no external private equity, venture capital, or institutional investment. The firm differentiates through a consistent top-5 ranking among the best structural engineering firms to work for nationally (Zweig Group, 12+ consecutive years, #1 in 2017, #3 in 2021 and 2026), R&D partnerships with Villanova University and UC San Diego, and an equity-participation program for key employees and principals. Operational highlights include weathering the 2008 recession without layoffs, transitioning to remote work during COVID-19 using pre-existing technology investments, and a 2026 leadership expansion that added two new Principals and four new Project Managers to formalize multi-office leadership.
