Established in Maine in 1992 by Mark St.Germain, we are a professional consulting firm specializing in environmental site assessment and remediation, environmental health and safety (EHS) compliance, and civil engineering and permitting. Starting in 2025, we are proud to be part of Aventia, backed by Bernhard Capital.
Our familiarity with federal, state, and local agencies — combined with expertise in environmental science and engineering — has resulted in streamlined services for our clients, saving them time and money while achieving their goals. Because of our familiarity with regulatory processes and in-depth industry knowledge, St.Germain can provide invaluable services and support to private businesses and government entities at all levels — giving them more time to do what matters.
Our clients include energy suppliers, waste & recycling companies, manufacturers, financial institutions, aggregate producers, affordable housing developers, and state and local governments. We help clients throughout New England and the United States.
