Mark, New England Clean Energy’s founder and president, is the only nuclear engineer we know making a living selling solar panels.

He achieved that by founding New England Clean Energy in 2006.

Mark is a NABCEP-certified PV Technical Sales Professional and former treasurer of the Solar Energy Business Association of New England (SEBANE). In 2012, he was named Worcester Business Journal’s Small Business Leader of the Year.

He has a master’s degree in energy engineering and a bachelor’s in nuclear engineering from UMass Lowell. Mark lives in Hudson and is very active in the community, including regular turns on the stage in regional theatre productions. He has been married 30 years and has triplets and multiple cats.
