What PEA Group does

PEA Group is a privately held, integrated site design services firm headquartered in Auburn Hills, Michigan, founded in 1947 (originally as PEA, Inc.) and rebranded in 2020. The firm delivers civil engineering, land surveying, landscape architecture, geotechnical engineering, ecological consulting, environmental consulting, and facility consulting services under a single multidisciplinary umbrella, organized around 12 project-type verticals including healthcare, automotive tracks, higher education, K-12, commercial, industrial, residential, parks and recreation, senior living, non-motorized transportation, utilities and energy, and water resources. Notable project references include an 850,000 SF Amazon distribution facility in Romulus, Michigan, the M1 Concourse automotive performance venue, McLaren Greater Lansing Hospital, and multi-year K-12 bond programs for Hartland Consolidated Schools and Rochester Community Schools. The environmental and ecological consulting capabilities are delivered through the wholly-owned ASTI Environmental division, acquired in April 2024.

The company employs 101-250 people across eight offices in Michigan (Auburn Hills, Brighton, Detroit, Okemos/Lansing, Washington, and Grand Rapids via ASTI) and Houston, Texas, the latter established through a 2020 merger with Brewer Engineering. PEA Group operates a B2B professional services model, earning revenue through hourly billing, fixed-fee project contracts, and retainer arrangements with government, institutional, healthcare, education, and commercial clients. Business is secured through direct project engagement, leadership-led business development, RFP responses for public-sector work, industry event participation, and community engagement. The firm holds professional licenses in more than 20 states, has earned regional recognition as a Crain's Best Place to Work for seven consecutive years, and pursues growth through organic expansion, targeted acquisitions, and internal shareholder development. PEA Group has remained independent since founding, with no external private equity or venture capital investment.
