Its Massachusetts electrician licence, #21143, is active on the state registry, held by Mark A. Contonio.
MAC Electric is the only referral I give when someone asks. They literally could not do any better in terms of response time, customer service, aptitude, attention to detail, punctuality, and logistical focus. Mark and his crew are top of the game and eager to take as much pride in your home, business, or project as you do. I’ve dealt closely with Mark, Eric, Garrett, and Alexis and have been impressed at every interaction. They have worked on my property and in my business build over months and with nothing but diligence, professionalism, responsiveness, and a personalism that is unmatched. Do not hesitate to use them for any electrical need or project. Wonderful people all of them.
