Accounting Industry Honors Reflect Firm’s Diversified Approach to Serving Clients

Maner Costerisan has expanded well beyond traditional tax, accounting, and audit services, fueling growth through the firm’s technology and cloud solutions, wealth management, and consulting services. While tax and audit remain core strengths, this diversified model has positioned the Michigan-based firm as a modern accounting powerhouse, reshaping perceptions of how a CPA firm can support its clients and earning national recognition in the process. Maner recently earned two major industry distinctions tied to business revenue growth:

• INSIDE Public Accounting’s 2025 Top 200 list – ranked No. 122, up from No. 127 in 2024, No. 140 in 2023 and No. 159 in 2022. In just three years, Maner has climbed 37 spots, a rapid rise that underscores the strength of its growth strategy. The IPA Top 500 ranks CPA firms nationwide by net revenue, from the Big Four to regional and local firms.
• Accounting Today’s 2025 Wealth Magnets list (Top Firms by Assets Under Management) – recognized for the second consecutive year as a leading wealth management provider. Maner Wealth, launched in 2020, first earned a spot on the list in 2024 and continues to expand as a trusted resource for clients seeking comprehensive wealth management and advisory services.

  “This national recognition is the result of a clear strategy to invest in people, technology, and services that meet our clients’ evolving needs,” said Trey Williams, CPA, president of Maner Costerisan. “Our focus is on delivering forward-thinking, holistic solutions that help businesses, nonprofits, and families navigate today’s complexity and prepare for tomorrow’s opportunities.” These distinctions highlight the strength of Maner’s diversified model and its commitment to helping clients thrive across multiple dimensions of financial and organizational strategy.   “Growth isn’t happening in just one area,” Williams added. “By diversifying, we’re able to deliver a complete set of solutions, whether that means helping a business modernize its technology systems, supporting a nonprofit’s financial strategy, or guiding a family through generational wealth planning.” The annual IPA rankings, established in 1987 by The Platt Group, are recognized as the gold standard for evaluating the state of the accounting profession. Accounting Today, a leading national news provider for the accounting industry, annually publishes rankings of the top public accounting firms.
