Global professional services firm Andersen has opened its first office in Georgia after merging with Atlanta-based tax and accounting firm Berman & Associates.
Financial terms of the deal weren’t disclosed. As part of the transaction, Andersen is integrating the team of tax and accounting professionals from Berman & Associates, as well as founding partner Stephen Berman and partner Ronald Green. Berman and Green will become managing directors in Andersen’s new Atlanta office and will join the firm’s Private Client Services practice.

In addition, Andersen named Conor LeFevour, an experienced Andersen managing director from Chicago, as its new Atlanta office managing director. LeFevour will oversee operations and growth while maintaining the individual, estate and trusts client relationships developed by Berman and Green. He will be joined by Peter Speranza, also from Chicago, who will grow the business services practice with a focus on integrated tax strategies for commercial clients.
The M&A deal with Berman & Associates expands Andersen’s Southeast presence and aligns with its global growth strategy.
“Atlanta has long been a strategic priority for Andersen,” Andersen Global Chairman and CEO Mark Vorsatz said in a statement. “Its vibrant economy, connectivity, and entrepreneurial spirit make it an ideal base to serve clients and grow our capabilities across the region.”
Berman & Associates has several decades of experience serving high-net-worth individuals, fiduciaries, and closely held businesses.
“Stephen and Ron have built an outstanding practice rooted in integrity, trust, and long-term relationships,” said Dan DePaoli, U.S. country managing director at Andersen. “Together, we have a tremendous opportunity to serve our clients and community and build Andersen’s future in Atlanta.”
Joining Andersen marks an exciting new chapter for Berman & Associates’ team and the firm’s clients, Stephen Berman said.
“We’re able to preserve the personal service our clients value while unlocking the resources and reach of a global firm,” he added.
