Key Highlights

  • Grizzly MEP is building a network of regional MEP companies to create a fully integrated platform across the eastern US

  • The company emphasizes maintaining individual company brands while fostering growth and operational efficiency

  • Centralizing back-office functions allows Grizzly to reduce costs, leverage buying power, and focus on expanding service capabilities

  • Technology plays a crucial role in Grizzly’s strategy, enabling better communication, operational efficiency, and cost savings through system integration

Consolidation is nothing new to the trades, whether it be through a franchise model or a straightforward series of acquisitions. While most of the recent consolidation activity has been on the residential service side of the industry, a new class of entrepreneur-investors is now eyeing the commercial side.

Back in May of 2025, Garnett Station Partners (GSP), a New York-based principal investment firm managing over $3.5 billion of assets, announced the launch of its commercial Mechanical, Electrical and Plumbing services platform, Grizzly MEP, with the aim of partnering with best-in-class founders and management teams across the United States to build a network of leading service providers.

Since that launch Grizzly has brought four companies under its umbrella:

  • Stiles Heating, Cooling & Plumbing, a company serving Georgia and South Carolina since 1970
  • Air Design Systems, a trusted name in the Southeast for more than 50 years delivering mechanical and plumbing solutions across Florida, Alabama, Georgia, Louisiana, and Mississippi
  • Excel Mechanical Contractors, based in Baltimore, Maryland, and founded in 2010, with a service footprint extending across eight Mid-Atlantic states.
  • Vermont Mechanical, Inc., founded in 1988, a full-service contractor providing mechanical systems for commercial, institutional, and industrial clients across Vermont, New Hampshire, and New York

In July, Grizzly MEP named John K. Adams as its CEO. Adams has held senior executive positions in both global publicly traded companies as well as privately held and private equity-backed organizations. He has successfully led and integrated several of these companies with successful outcomes over the past decade.

CONTRACTOR spoke with Adams about Grizzly’s business model, and their plans to create a fully integrated MEP platform along the eastern seaboard and beyond.

CONTRACTOR: How would you describe the Grizzly MEP value proposition?

Adams: So our model is pretty simple. We find these great companies—we're not looking for depressed assets or companies in need of a turnaround—companies that have good track records, stable customer bases and a solid foundation, but that need help to get to the next level.

What I mean by that is, a lot of the of these owners are really distracted by the back office, things like payroll and legal and insurance, the administrative things that consume a lot of their time and bandwidth. With our platform we centralized a lot of those back-office functions and allow them to focus more on growth and serving their customers. We put systems in place and also offer technology that allows their technicians to be more efficient, more effective.

Then we share best practices amongst all the businesses. You'll find that one business may be great at a certain aspect of what they do and other businesses are able to benefit from that as well.

CONTRACTOR: When a company joins Grizzly MEP, do they take on your branding, or do they still operate under their own separate identities?

Adams: The brand stays completely intact. I'm more focused on integration and driving growth than I am rebranding. And lot of times rebranding can create customer confusion.

What will happen, six months or a year down the road, is X Mechanical will become X Mechanical: A Grizzly Company. That way when we’re going after, say, a national contract, and someone asks, well, how can you service me in a market where you don't reside? We can say, well, there are all these various companies that are all part of the Grizzly family.

CONTRACTOR: Why do you think there’s so much consolidation happening in the mechanical contracting industry, in the MEP trades?

Adams: I'm not a member of a private equity firm, I'm an operator. But from what I've seen, a lot of private equity groups are saying, hey, the industrials are a great sector because they're always in demand. It’s a necessary part of commerce and society.

Now, in the MEP space, a lot of these sponsors are seeing that residential side is a bit more sensitive to economic fluctuations, whereas on the commercial side having properly operating systems is mission critical. They're less sensitive to those economic changes than the residential side.

So, we're seeing a lot more focus in the commercial sector—buyers have gotten a much more comfortable with the overall model. I don't want to say [the commercial side] is recession-proof, but it's highly insulated.

CONTRACTOR: You mentioned technology as one of the keys to growth. With so many platforms, so many systems—often multiple platforms in a single company—how are you handling integration?

Adams: We're in the process right now of selecting systems, both financial and operational, that we will implement across the entire enterprise, because we want everyone on the same platform. It gives us the ability to communicate better. It gives us the ability to operate better, gives us the ability to share best practices, leverage our size and perform.

I want to be clear, this isn't about buying a bunch of companies, putting them together, stripping out costs, repackaging them and selling them to make money off the arbitrage. We’re taking these companies, we're integrating them, and we're centralizing some of the back-office work to get costs out of the system. Then we can leverage our buying power for things like insurance and benefits and vehicles and technology—things that a standalone business would not be able to do.

That’s how we drive profitability. And then as we change the sales model and get more externally focused, it gives us the ability to really get these businesses performing at higher levels. The tech stack is going to be a very big part of that.
