Howard Hanna Real Estate Services has expanded into the Northern New England market through a new partnership with Portside Real Estate Group, a Maine-based firm with offices across the state and in New Hampshire and Massachusetts.
Founded in 2012 and led by Dava Davin, Portside has grown from a single office in Portland into 12 offices and more than 225 agents. The partnership announcement follows Portside’s strongest 12-month stretch on record and $1.5 billion in sales in 2025, capped by its best month ever and the No. 1 spot for residential sales volume in Maine for June. Portside will continue operating under its local leadership.
“Portside is getting stronger,” said Davin. “We’ve built something really special together, and I am so proud of the culture, the relationships, and the sense of purpose that defines Portside. Partnering with Howard Hanna lets us protect everything that makes us unique while opening doors we couldn’t open on our own.”
“We are committed to thoughtful, disciplined growth by partnering with market leaders who share our entrepreneurial, relationship-driven approach,” said Hoby Hanna, CEO of Howard Hanna. “Portside has built an extraordinary company with dominant market share. This alliance proves that by joining forces, independent, family-owned brokerages can deliver the national scale and institutional resources that benefit both agents and the clients they serve, while preserving the agility and local decision-making that define independent companies.”
