While working as an environmental technician on a major petroleum account for a competitor, Doug found himself drawn to the entrepreneurial spirit of ECS and made the move in April 1999. He went to work at ECS’ Brattleboro, Vermont office, which at the time was a rambling red barn situated on acres of farmland. As a project manager, Doug focused on site assessment and brownfield redevelopment services for municipalities, private developers and community development corporations.

Doug transferred to ECS’ headquarters in Agawam, Massachusetts in early 2000 and took on the responsibility of managing the company’s site assessment group. That same year, with the assistance of ECS, he completed his Masters of Business Administration degree.

Upon his return from a two-month sabbatical hiking along the Appalachian Trail from Maine to Massachusetts, Doug began managing ECS’ accounting department and became Controller and Business Manager. The company was growing quickly at the time, and Doug’s shrewd business planning was a key factor in ECS acquiring another environmental firm in late 2002.

Doug’s financial leadership over the next few years led to him becoming ECS’ Chief Financial Officer in January 2008. He continues to manage the company’s accounting group and is also the ESOP trustee on the Board of Directors.

Mike joined ECS in 1989 as Chief Financial Officer (CFO) and was tasked with developing financial systems and reporting mechanisms for a business that was still getting off the ground at the time. “When I came in 1989,” Mike says, “we only had two computers, and people had to take turns writing their field reports.”

As the company began to grow, Mike took on the responsibilities of managing ECS' banking, insurance and human resource functions. When the building that now serves as corporate headquarters was constructed in 1990, he obtained the financing and oversaw all aspects of the development. For the next 17 years, Mike's financial direction and expertise led to the start-up of 11 branch offices and the acquisition of a handful of small businesses.

In late 2007, as part of a senior management transition plan and in conjunction with the implementation of ECS' Employee Stock Ownership Program (ESOP), Mike relinquished the title of CFO to Doug McVey . Mike continues to serve as ECS' Treasurer and in that capacity oversees the company's financing and insurance relationships. He is also a member of the Board of Directors.
