The deal expands Wipfli’s footprint to Missouri and Southern California while adding to its employee base in India. As part of the deal, all of Mueller Prost’s 221 associates, including 21 partners, will be joining Wipfli. Wipfli will have more than 2,900 associates after the merger and about 300 partners. Financial terms of the transaction were not disclosed. Wipfli ranked 19th on Accounting Today’s 2021 list of the Top 100 Firms, with $401.81 million in annual revenue. Mueller Prost ranked 18th among the Regional Leaders in the Midwest, with $24.8 million in annual revenue.

"There are so many points of connection between Mueller Prost and Wipfli, it would be hard to say what I'm most excited about,” said Wipfli managing partner Kurt Gresens in a statement Tuesday. “While it was their entrepreneurial spirit that brought us together, our strong industry and services synergies and longstanding cultural connections between our teams will allow us, together, to bring even more value to the clients we serve and enhance our growth. We look forward to expanding Wipfli’s presence into Missouri and Southern California while adding to our talent base in India."

Mueller Prost’s client base focuses on closely held businesses and organizations in the health care, manufacturing, distribution, nonprofit, real estate and construction industries.

“We are excited to join the Wipfli team,” said Mueller Prost co-founder and president Doug Mueller in a statement. “We are grateful to our clients and our people who have helped us become who we are today — and we look forward to this next step in serving our clients in an even greater capacity together.”

Mueller Prost is the second firm to join Wipfli this year after a merger with Hughes & Company in Denver in January. Last year, Wipfli expanded in Portland, Maine, by adding a technology consulting firm, Tidestone Solutions, in Chicago with another technology consulting firm, Punchkick Interactive, and in Denver by adding advisory firm Stratagem.
