What Larson Design Group does
Larson Design Group (LDG) is a privately held, employee-owned architecture, engineering, and consulting firm headquartered in Williamsport, Pennsylvania, founded in 1986. The firm operates 19 offices across the United States and has executed projects in all 50 states over more than 40 years, offering multidisciplinary services across 11 markets (Commercial, Community, Education, Energy, Federal, Healthcare, Light Industrial, Retail, State and Local Government, Transportation, and Water/Wastewater) and 15 service disciplines including civil, structural, transportation, geotechnical, M/E/P/FP, environmental, GIS/asset management, landscape architecture, planning, permitting, surveying, and alternative delivery (design-build and P3). Notable project credentials include LEED Platinum (CVS flagship), LEED Gold (Dominion Office), and WELL Building Standard Gold (Oklahoma National Guard Wellness Center), with recent awards including ENR 500 ranking (#238 in 2025), ACEC/PA Diamond Awards, and ESWP Innovative Project of the Year.
LDG generates revenue through project-based professional services engagements delivered under direct enterprise sales and qualifications-based selection. Its customer base spans federal and state government (PennDOT, Oklahoma Military Department, NCDOT via MI Engineering, 29 transit authorities) and large private-sector clients running multi-site rollouts (CVS Pharmacy, Dave & Buster's, Sheetz, Party City). Marketing is led through the corporate website, ENR/AEC industry rankings, regional awards, and an employee-ownership narrative deployed across LinkedIn, YouTube, and other social channels to support recruiting and pursuit positioning.
The go-to-market is anchored by long-tenured enterprise client programs that produce multi-year backlog, augmented by state DOT and federal work won through qualifications-based selection. Strategic growth is executed via acquisitions (most recently MI Engineering in March 2026 to deepen transportation capabilities in the Southeast) and through senior leadership continuity, with David Schaarsmith transitioning from COO to President and CEO in January 2026 after a five-year tenure during which the firm expanded into three new states, established a federal practice, and nearly doubled annual revenue.
