Doeren Mayhew, a national assurance, tax and advisory firm, announced it has grown again in West Michigan with its acquisition of Novotny CPA Group, effective Nov. 6, 2025. 

Novotny CPA Group is a full-service accounting firm that has served businesses and their owners along West Michigan’s coast for more than 40 years with accounting, tax and auditing services. All Novotny CPA Group’s team members have relocated to Doeren Mayhew’s Grand Haven and Grand Rapids offices, continuing with the firm in their current roles. The firm’s partners, Randy Novotny and Tom Winkelman join the firm as principals.

“It’s an exciting time for our firm as we continue to grow our presence in West Michigan,” says Joshua Garvey, West Michigan’s managing principal at Doeren Mayhew Advisors, LLC. “Since Doeren Mayhew entered the West Michigan market in 2022, the goal has been to continue building our brand in the marketplace and expanding local technical expertise and resources for our clients. Acquiring firms, such as Novotny CPA Group, with this shared vision and commitment to our communities allows us to achieve that. We’re excited to welcome Randy, Tom and the team to the Doeren Mayhew family.”

Today, Doeren Mayhew is recognized as the 8th largest CPA firm in Michigan with nearly 450 team members in the state and more than 825 nationally. The integration of Novotny CPA Group strengthens the current footprint in West Michigan for Doeren Mayhew, while enhancing its core tax and audit practices, and deepening its bench strength of advisors. The firm has completed four acquisitions in the region within the last year, solidifying its commitment to strategic growth in the market.
