Senior Consultant - Air Quality


Epsilon is one of the best known and most respected environmental consulting firms in the northeast United States. Epsilon’s client base includes major energy, commercial real estate, aviation, institutional and residential developers, as well as local and state public agencies. As a well-established, mid-sized firm, we are large enough to support our team members professionally and personally, and small enough to keep our focus on project successes and client satisfaction. Epsilon is privately held by its Principals, who are experts in their fields and work side-by-side with staff of all levels on complex, high-profile and interesting projects. A recipient of a Greater Boston Chamber of Commerce Award for Business Excellence, Epsilon has also been recognized twice as one of the Boston Business Journal’s Fifty Best Places to Work.
