Coldwell Banker Hearthside is extending its lead as one of Coldwell Banker’s largest affiliates, thanks to its acquisition of Lehigh Valley boutique firm Acre & Estate Brokerage.

Coldwell Banker Hearthside has 11 offices throughout Pennsylvania and New Jersey, and the acquisition of Acre & Estate marks its entrance into Lehigh Valley with three offices in Bethlehem, Brodheadsville and Wind Gap, Pennsylvania. Acre & Estate founder Eric Leadbetter will continue to lead his team as the president of Coldwell Banker Hearthside’s Lehigh Valley Division.

“This wasn’t just a market move. It was a culture fit,” Coldwell Banker Hearthside co-owner Jamie Mancuso said in a written statement. “Eric’s agents, his energy, his ideas — they will complement and elevate what we do companywide.”

Mancuso and Leadbetter said the acquisition enables the team to leverage the best parts of each other’s companies — Coldwell Banker brings enhanced technology and support, while the former Acre & Estate team brings invaluable knowledge about Lehigh Valley and the elevated customer service and modern branding that comes with boutique real estate.

“What drew me to Hearthside was their independence, their innovation, and their clear sense of identity,” Leadbetter said in a prepared statement. “This isn’t a corporation absorbing a boutique firm. It’s two philosophies aligning. We’re not just adding volume — we’re scaling values.”

Added Mancuso, “We’re not waiting on the market. We’re moving forward. We’re betting on good people, doing things the right way, and building something great — together.”

Alongside the acquisition of Acre & Estate, Coldwell Banker Hearthside is appointing another regional leader.

Longtime Hearthside team member Stefanie Hahn will serve as president of the Delaware Valley region. This model, the brokerage said, supports growth while prioritizing the company’s tight-knit culture. Hearthside owners Jamie and Robin Mancuso will continue to lead the company’s daily operations, while Hahn and Leadbetter oversee regional expansion.

“We don’t have layers and layers of management,” Mancuso said. “Our agents call me directly. They know we’re all in this together.”
