Doeren Mayhew enters NY market with acquisition of Rochester-based 1RDG
Listen to this articleDoeren Mayhew has entered the New York market through the acquisition of 1RDG, a Rochester-based advisory firm, effective Jan. 20, marking the firm’s first acquisition of 2026 and a strategic expansion into Upstate New York.
Founded in 2005 by John Rizzo and Brian DiGiacco as a boutique accounting firm, 1RDG has grown into what it describes as Upstate New York’s financial center, integrating compliance, management and advisory services on a single platform. The firm has built a regional presence serving middle-market companies and private clients across multiple industries.
The transaction establishes two new Doeren Mayhew offices in New York and adds advisory depth that complements the firm’s existing audit, tax and outsourced accounting services. Both organizations gain expanded industry coverage, particularly in construction, health care, real estate, manufacturing and private family offices.
“What made this opportunity stand out wasn’t just the significant market, it was the people,” said Chad Anschuetz, CEO of Michigan-based Doeren Mayhew Advisors, LLC. “The 1RDG team thinks like entrepreneurs and serves clients the way we do. While New York surfaced as a unique opportunity along our growth journey, it became a very natural next step.”
In advance of the acquisition, 1RDG expanded its regional footprint through partnerships with Bailey Carr, CPAs in Rochester, and Bahgat & Laurito-Bahgat, CPAs in Fredonia. Those firms are joining Doeren Mayhew concurrently as part of the transaction.
Together, the New York firms bring more than 100 employees and seven partners to Doeren Mayhew, including Brian DiGiacco, Cory Raggi, Christopher Gamble, Timothy Hern, Ryanlynn McCollum and Lori Jansen. Rizzo will continue to lead the firm’s New York region as managing principal.
“1RDG has long been known as The Hustle Firm—always embracing growth, change and the push beyond our comfort zone,” Rizzo said. “As our industry undergoes rapid transformation, the timing couldn’t be better to join a forward-thinking, historic firm like Doeren Mayhew. “From our very first meeting with their team, it was clear the culture and opportunity were the perfect fit.”
