What Sevee and Maher Engineers does

Sevee & Maher Engineers (SME) is a privately held, multidisciplinary engineering and environmental consulting firm founded in 1985 by John Sevee and Peter Maher and headquartered in Cumberland, Maine. The firm employs 130+ professionals — engineers, geologists, hydrogeologists, chemists, scientists, industrial hygienists, and technicians — across eight U.S. offices in Maine (Cumberland, Bangor, Hampden), Arizona (Phoenix), Georgia (Marietta), Illinois (Park Ridge, Aurora), and New Jersey (Lambertville), with professional engineering and geology licensure in 35+ states. SME serves commercial, industrial, municipal, and government clients through ten core service lines: civil engineering and permitting, solid waste engineering, power and utility engineering, environmental health and safety management, site investigation and remediation, brownfields redevelopment, industrial hygiene and indoor air quality, geotechnical engineering and testing, product stewardship, and water resources consulting. The firm also holds two granted U.S. patents — the Packer-Purge System™ (U.S. Patent No. 11,021,937) for relief well purging in FERC-regulated dam safety applications and WellHawk™ for well redevelopment — and maintains an in-house geotechnical laboratory that has operated for more than 35 years.

SME generates revenue through project-based professional services engagements billed via hourly fees, project-based contracts, and ongoing consulting arrangements with no channel partners or resellers. Go-to-market is sales-led and direct, driven by long-tenured client relationships, referrals, and business development rather than formal demand generation. The customer base is horizontal across agriculture (Estabrook Farms and Greenhouses), pulp and paper (Woodland Pulp LLC), banking (Bangor Savings Bank), renewable energy developers, municipal governments, real estate developers, manufacturers, and food and beverage companies seeking product stewardship. Scale signals include 100+ landfill clients across the eastern U.S., 200+ ground-mounted solar projects totaling 700+ MW since 2009, and multiple 30+ year client relationships. Pricing is quote-based and project-specific and is not publicly disclosed.

The firm has grown both organically and through acquisition, completing three acquisitions (Environmental Safety & Hygiene Associates in 2018, Bono Consulting in 2022, and James W. Sewall Infrastructure Engineering and Survey in 2026) and launching new service lines including Product Stewardship (2020), Brownfields Redevelopment (2023), and Power and Utility Engineering Services (2024). Leadership transitioned from co-founders John Sevee (retired 2014) and Peter Maher (retired 2024) to current President Erik M. Clapp, who joined as a geologist in 1998 and assumed the presidency in 2019. The company remains privately held with no disclosed revenue, funding, or ownership structure beyond a principal-led management team.
