What Makes Us Stand Out

Mabbett was established in Massachusetts in 1980. Today, with five offices along the eastern seaboard, Mabbett offers access to a wide range of professionally experienced and credentialed staff. Mabbett is a recognized small business and award-winning leading provider of environmental consulting, health and safety, and architectural/engineering design services. These services are provided to Federal, state and local agencies, and private commercial, institutional and industrial clients nationally.


Attention to your needs and schedules is unsurpassed.


By focusing the appropriate resources on your project, we can accomplish your requests in a timely, professional manner. You can depend on us with complete confidence for assistance in achieving your goals.


Mabbett has the technical ingenuity to understand each project in depth, and the real-world experience to design and implement practical solutions which make sound business sense and provide the best value to our clients.

Our History

Mabbett was founded by Arthur N. Mabbett and was incorporated in Massachusetts in 1980. The firm is a privately held Chapter “C” Corporation. In 2007 Mabbett acquired the Environmental, Health and Safety (EH&S) Services Division of MasiMax Resources, Inc. in Virginia and established a Washington, D.C. presence. Mabbett’s growth continued with the opening of regional offices in Rhode Island in 2008, New Jersey 2012 and New York in 2018.

Mabbett is a U.S. Department of Veterans Affairs, Center for Verification and Evaluation (CVE), verified Service-Disabled Veteran-Owned Small Business (SDVOSB) due to Arthur Mabbett’s 19 years of meritorious service as a Major, Environmental Sciences Officer in the U.S. Army both on active duty and in the Army Reserves.
