Advanced Technology Group on Wednesday announced its plans to move to the Old Sawmill District, where it will take up temporary residence in Cambium Place before building a new office building in the growing district.

Tom Stergios, the senior vice president of the company's Missoula operations, said ATG will move from its Main Street location to Wyoming Street by the end of the year.

“We've been scouring any downtown location, even non-downtown locations, and we really wanted a place where we could spread our wings,” Stergios said Wednesday evening. “We don't know how big we'll be, but we're measuring it in the multiple hundreds, so we felt a campus approach was the right approach.”

At 190,000 square feet spread across four floors, Cambium Place represents one of the largest projects to break ground in downtown Missoula. While it remains under construction, it's expected to open this year.

Stergios said the search for a new location was long, though he believes ATG and the Sawmill District will prove to be a good match.

“We liked their vision,” said Stergios. “There's multiple tech corridors being proposed, and I think this is going to be one of them.”

ATG began with two employees in Missoula in 2011, though it has since grown to 130 employees and an annual payroll pushing $7 million.

Initially, ATG will occupy the top two floors of Cambium Place, but will look to build an additional office in the area to accommodate future growth.

“Ultimately, Cambium won't contain us, so we're looking at building the campus part of it,” Stergios said. “There's a couple of locations in proximity that are options for building a building.”

Stergios and Ed Wetherbee, one of the developers behind the Old Sawmill District, believe ATG will anchor future tech-related companies in the district.

ATG consultants are experts in implementing cloud-based customer and revenue management solutions for leading enterprises around the globe.

“This will support ATG employees and broader efforts toward technology development and innovation,” said Wheterbee.
