PKF O’Connor Davies acquires Wolf Maryles & Associates

PKF O’Connor Davies, a Top 25 Firm based in New York, has added Wolf Maryles & Associates, also headquartered in Manhattan, effective Jan. 1, 2026. 

The deal expands PKFOD’s private client services, especially tax and financial management advisory services catering to high-net-worth individuals and families, guiding clients through sophisticated tax and wealth transfer strategies. 

Financial terms of the deal were not disclosed. PKFOD ranked No. 25 on Accounting Today‘s 2025 list of the Top 100 Firms, with $410 million in annual revenue, over 200 partners, more than 1,700 employees and 19 offices. The acquisition of Maryles & Associates adds 11 new team members to PKFOD, all in its New York City office.

“We’re excited to welcome Shimon Wolf and the accomplished team at Wolf Maryles & Associates to the PKF O’Connor Davies family,” said PKFOD CEO Kevin Keane in a statement Monday. “Their knowledge and approach complement our strengths and ability to deliver the highest level of insight, service and value to our clients.”

Wolf Maryles & Associates has been in business for over 25 years, and its team includes CPAs and professionals with advanced degrees in tax and accounting.

“Our team is excited to join PKF O’Connor Davies and continue serving our clients with the same depth of expertise and personalized attention,” said managing member Shimon Wolf in a statement. “Combining our resources and insights with the broader PKF O’Connor Davies network creates great opportunities to expand and elevate the service we deliver.”

Last November, PKFOD announced that it had received funding from Investcorp, a global alternative investment firm, and the Public Sector Pension Investment Board, one of Canada’s largest pension investment managers. This past June, it merged in Rainer & Co., based in Philadelphia.
