Our MCS Team

The MCS team brings a total of more than 120 years experience to every project. The team first worked together over a decade ago for a large, well-known New England contractor and later would build a very successful mechanical systems division from the ground up for another contractor in the late 1980’s. MCS was founded in 1996 on the principles of steadfast honesty and excellence. The team has continued to build enduring relationships with both clients and subcontractors as a result.
