De Pere-based Tweet Garot Mechanical in late February announced it acquired Marquette, Michigan-based HVAC and plumbing firm Prime Specialty Contracting.
It’s the most recent Michigan firm acquired by Tweet Garot. Company officials said Tweet Garot was the leading mechanical contractor in the Upper Peninsula after the acquisition.
Tweet Garot leadership didn’t share details of the deal but said they had a relationship with Prime Specialty Contracting’s founder. Prime has offices in both Marquette, Michigan and Escanaba, Michigan.
“I’ve known Prime’s founder Cory Bushong for many years, and I’ve watched him build something truly unique,” said Christopher Howald, chairman and CEO of Tweet Garot, in a statement. “In just six years, Cory and his team have built a business and a culture that stand out in this industry. We didn’t pursue Prime because of geography alone – we pursued them because of the people, the reputation and the values they’ve established. Together, we believe we can create the dominant destination for both employees and customers in Upper Michigan.”
Bushong will remain at the company permanently and will continue to lead his team of around 90 employees, officials said.
Prime Specialty Contracting operates three divisions: Prime Mechanical Contracting, Prime Plumbing, Heating & Cooling and Prime Welding & Fabrication. The company serves residential, commercial and industrial clients throughout the Upper Peninsula.
Both the Marquette and Escanaba facilities will remain open and in full operation.
“When I started Prime in 2019, the goal was always to build something our team and community could be proud of,” Bushong said in a statement. “Partnering with Tweet Garot gives us the resources, technology, and scale to take that vision even further – without changing what makes us who we are. I’m excited about what this means for our employees, our customers and the Upper Peninsula.”
“The synergies between our organizations are natural,” said Hope Voigt, president and COO of Tweet Garot. “We share the same commitment to culture, employee development and customer relationships. With Prime’s deep roots in the UP and Tweet Garot’s resources and technology platform, we’re positioned to offer something no one else in the region can match.”
In November, Tweet Garot announced it acquired Temperature Control in Traverse City, Michigan.
Company locations include De Pere, Wisconsin Rapids, Wrightstown, Tomahawk, Altoona, Gladstone, Michigan and Tempe, Arizona.
