The Clark Enersen Partners

What The Clark Enersen Partners does

The Clark Enersen Partners is a privately held, employee-owned architecture and engineering firm founded in 1946 in Lincoln, Nebraska, by Harvard graduates Kenneth B. Clark and Lawrence A. Enersen. Operating as an integrated multidisciplinary practice, the firm delivers 18 in-house services spanning architecture, civil, structural, mechanical, and electrical engineering, landscape architecture, interior design, laboratory planning, energy modeling, commissioning, digital experience design, and construction administration. With 180+ professionals distributed across eight U.S. offices (Nebraska, Missouri, Kansas, Colorado, Oregon, Iowa, South Carolina), it serves higher education, healthcare, government, PK-12 education, corporate, civic, science and technology, sports/recreation, worship, planning, and housing clients through project-based, multi-year professional services contracts secured via RFPs, referrals, and long-term relationship management.

The firm's revenue model is project-based professional services pricing on multi-year contracts, with billings determined by scope, complexity, and project requirements rather than disclosed tiered pricing. Its go-to-market relies on enterprise field sales through direct client engagement in regional offices, supported by content marketing (newsletters, white papers), conference presentations, and organic social (LinkedIn, Instagram, Facebook). The firm differentiates on its integrated "under one roof" multidisciplinary delivery, deep specialization in BSL-3/clean room laboratory planning, LEED-certified sustainable design, and a portfolio of marquee projects including the $121 million UNMC Davis Global Center, the LEED Gold CSU Spur Vida building, and the SDSU Animal Disease Research and Diagnostic Laboratory.

The business is privately held with no external investors, parent company, or public listing, and exhibits strong employee tenure (multiple staff with 15-50 year anniversaries) alongside active internal promotion cycles (16 promotions in 2025, 25 in 2026). Geographic expansion into the Southeast, Pacific Northwest, and Front Range, combined with a formalized Science and Technology sub-practice, indicates ongoing investment in capability depth and market reach.
