Maner Costerisan strengthens Grand Rapids presence with new office

Maner Costerisan, a full-service public accounting and business consulting firm, marked its continued growth in West Michigan with the opening of its expanded Grand Rapids office, reinforcing the firm’s investment in the region.

The firm celebrated the expansion Sept. 30 with a ribbon-cutting ceremony and open house at its new office in Centennial Plaza, 2851 Charlevoix Drive SE, Suite 300, Grand Rapids. Members of Maner Costerisan’s team joined representatives of the Grand Rapids Chamber, clients, community partners and other guests for the events.

The new office follows Maner Costerisan’s January 2026 combination with Grand Rapids-based Baker Holtz, which added three partners and 28 team members to the firm and expanded its expertise and capabilities in West Michigan. Maner Costerisan now has more than 230 team members across its Lansing and Grand Rapids offices, including 57 professionals based in Grand Rapids.

“This is an exciting new chapter for Maner Costerisan in Grand Rapids,” said Trey Williams, CPA, president of Maner Costerisan. “Our growth allows us to bring even greater depth and expertise to the businesses and organizations we serve while continuing to invest in the relationships that have long connected our team to West Michigan.”

Steven Struck, CPA, principal, brings more than 20 years of experience serving businesses in the Grand Rapids area. A former principal with Baker Holtz, he joined Maner when the firms combined in January.

“Grand Rapids is home, and relationships have always been at the heart of how we do business,” Struck said. “This office brings our growing team together in a space where we can collaborate with each other, work alongside our clients and continue building on the relationships we’ve developed throughout West Michigan.”
