A Family Company

Celebrating 50 Years in Business

From our humble beginnings as a local contractor in The Berkshires run by the Dobbert family, The Dobbert Companies has evolved into one of the leading mechanical contractors in Massachusetts.

In 1974, Eleanor and Tom Dobbert launch Dobbert Heating & Air Conditioning in North Adams, MA, with a focus on the same trades as we work in today: fire protection, HVAC, plumbing, and sheet metal.

Building the Foundation

1970s

The Berkshires evolves into a hospitality and arts hub, and Dobbert develops a specialty in these markets starting with Mass MoCA, the world’s largest contemporary arts museum (that takes over Sprague’s manufacturing facilities in North Adams). The company rapidly adds many notable clients in these arenas including Miraval (then Cranwell Resort), Tanglewood, and The Red Lion Inn.

Navigating Choppy Waters

1980s

Jimmy Dobbert, the brother of company founder Tom Dobbert, joins the company as the lead foreman in the mid-1990s, professionalizing our field operations. He remains with us to this day!

– Richard Melville, CEO, Five Star Properties

I was at Mass General Hospital with one of my siblings who was undergoing surgery and I got a call that the boiler went down at The Chicken Box. It was during a winter storm and your CEO Mike Dobbert was at our door himself within an hour to make sure that the boiler was fixed so we could keep our doors open. Talk about customer service!

– Rocky Fox, Co-Owner, The Chicken Box

Can’t say enough about a large group of humans you can trust and depend on in brutal situations. Whether it’s new installs in historic buildings, or emergencies on weekends and holidays, they’ve always been there for me, through the sand and the mud!

– Nathan Skerritt, Director of Operations, Nantucket Island Resorts

We have worked with the Dobbert team for years. We always appreciate their prompt service and attention to detail, especially with the discerning clientele we serve at Lola 41.
