Aprio has struck a deal to acquire RSM US LLP's Professional Services+ practice in the U.S. and Canada. The PS+ practice serves nearly 80 firms across the U.S. and Canada and offers services related to strategy and leadership, talent development, business processes and operations, and access to group buying solutions. 

The deal is expected to close April 30, subject to closing conditions, and the PS+ practice will operate as part of Aprio effective May 1. The current leader of RSM's PS+ practice, Dean Sengstock, will continue to lead it and join Aprio as a partner along with four other partners and over 30 team members. 

"In joining Aprio, we have a unique opportunity to carry forward our vision and customized approach for serving clients the way they want to be served," Sengstock said in a statement Friday. "While we are joining a new firm, our team, the services we provide, and our commitment to exceptional client-centric service, remains the same." 

Financial terms of the deal were not disclosed. RSM US, based in Chicago, ranked No. 5 on Accounting Today's 2025 list of the Top 100 Firms, with over $4 billion in annual revenue in fiscal year 2024, while Aprio, based in Atlanta, ranked No. 24 and earned over $485.34 million in annual revenue in FY 2024.

RSM had more than 17,000 partners, principals and employees in FY 2024. Of this total, 1,183 are partners and principals. Aprio has 204 partners. RSM's Professional Services+ Practice expects to bring five partners and 30 team members to Aprio. 

"It is an honor to welcome the PS+ practice, clients and team to Aprio. RSM has provided an exceptional platform for the past four decades for the PS+ practice and we are committed to establishing a strong foundation to grow the practice at Aprio," said Aprio CEO Richard Kopelman in a statement Friday. "With the addition of the PS+ practice, Aprio will include a robust community of complementary firms with unique opportunities for collaboration and growth as we invest in the future." 

Aprio received a private equity investment last July from Charlesbank Capital Partners. Earlier this month, Aprio acquired JMS Advisory Group in Atlanta. Aprio has completed over 20 mergers and acquisitions since 2017.

"We believe this transaction enhances the PS+ team's ability to continue supporting their clients, while enabling RSM to focus on our core assurance, tax and consulting service offerings for the middle market," said RSM US LLP managing partner and CEO Brian Becker in a statement. "We are grateful to the PS+ team for their many contributions to RSM over the last 40 years."  

Last October, RSM US and RSM UK announced plans to combine by the end of this year.
