The Verterre Group was founded in 1993 as Twin State Environmental Corporation (TSEC). Since 1993 we have been providing environmental consulting and field support services to a wide range of clients. In 2002, TSEC changed its name to The Verterre Group (Verterre). On December 29, 2006, Green Earth Environmental, Inc. purchased The Verterre Group (Verterre). Green Earth Environmental is owned by Verterre employees and continues doing business as The Verterre Group. The Principals are Martha Roy, Rod Lindsay II and Steven Chase. We pride ourselves on the fact that we are locally owned and live and work in the same communities that we routinely service. We are located at 414 Roosevelt Hwy, Colchester, Vermont, United States.
