Accounting Today acknowledges Michigan public accounting firm for continued growth

LANSING, Mich. – For the fourth consecutive year, Accounting Today has acknowledged Maner Costerisan as a leading accounting firm within the Great Lakes Region and as one of the ‘Top Firms to Watch’ nationally for the second year.

Maner Costerisan was ranked No. 29 on Accounting Today’s ‘Top Firms to Watch’ list, up from No. 37 in 2023. The annual ‘Top Firms to Watch’ list highlights leading firms nationwide by revenue beyond the Top 100 Firms—a list often cemented annually by billion-dollar firms or those that have undergone significant mergers and acquisitions.

Maner was also No. 21 among the top firms in the Great Lakes region, which consists of Michigan, Illinois, Indiana, Ohio, and Wisconsin. The Great Lakes region was the second-largest region nationwide in revenue, reporting an average growth of 11.45% over the past year. Maner’s growth rate of 20.3% was nearly double that average.

“These notable recognitions from Accounting Today continue to reaffirm our firm’s commitment to providing our clients with thoughtful, solution-based expertise to help them achieve their desired outcomes” said Trey Williams, CPA, Principal and president of Maner Costerisan. “Our team members are experts in their respective fields and these national distinctions reflect that expertise, which has largely contributed to our continued growth and success.”
