Harmsen & Associates

What Harmsen & Associates does

Harmsen & Associates, operating as Harmsen LLC, is a privately held professional land development firm founded by Bill Harmsen in Monroe, Washington in 1974. The company provides an integrated suite of six core services: civil engineering, construction staking, land surveying, land use planning, environmental services, and sUAS (drone) surveying. Headquartered in Everett with regional offices in Mount Vernon and Oak Harbor, Harmsen serves King, Snohomish, Skagit, Island, and Whatcom Counties in Western Washington, completing work for school districts, municipalities, residential and commercial developers, healthcare providers, faith-based organizations, and parks and recreation districts. The firm has completed more than 38,810 projects since 1974 for over 3,670 clients, with 45 employees carrying 201 years of combined professional experience.

Harmsen's business model is relationship-driven and sales-led, relying on quote-based project pricing, public-sector procurement, and referrals cultivated through deep membership in more than 16 industry associations and local chambers of commerce. Technology is centered on AutoCAD Civil 3D, precision survey instruments capable of 0.1-foot elevation accuracy, and a proprietary sUAS LiDAR aerial mapping workflow using FAA Part 107 licensed pilots and RTK-equipped drones with in-house data processing. The firm differentiates on sustainable, low-impact design with LEED AP accredited engineers, 48-hour construction staking response time, and a hard-to-replicate historical survey records archive built through acquisitions of Alpha Subdivision Professionals, HBA Design Group, and the records of Leonard Boudinot & Skodje, Fakkema & Kingma, Meriwether Leachman Associates, and Evergreen Surveying. Ownership remains founder/family-controlled, with David Harmsen serving as President and Director of Engineering and Doug Slager as CEO. Revenue and ownership structure are not publicly disclosed.
