BELLINGHAM — Larson Gross has added the team from Perry, Shelton, Walker, and Associates, PLLC, expanding the Washington-based accounting and advisory firm’s presence and advisory services.

The PSWA team, based in the Seattle metropolitan area, officially joined Larson Gross effective Jan. 1 and is now operating under the Larson Gross brand. Firm officials said clients should expect continuity of service along with access to expanded consulting services and technical resources.

“We’re excited to welcome the PSWA team to Larson Gross,” said Kelli Visser, CEO of Larson Gross. “From our first conversations, it was clear we share the same values—especially when it comes to building long-term client relationships rooted in trust, integrity, and proactive advice.”

The professionals who joined from PSWA continue to serve their existing clients while drawing on Larson Gross resources, the firm said.

“This is a meaningful alignment of purpose and people,” Visser said. “We’re proud to grow our firm in a way that stays true to our values, supports our team members, and most importantly, strengthens the service we provide to clients through the combined efforts of the PSWA and Larson Gross team.”
