Parsippany, NJ, August 14, 2025 — SAX, a top 100 national accounting, tax, and advisory firm, is pleased to announce its acquisition of Maddaloni, Nydick & Keenan, P.C. (“MNK”), effective November 15, 2025. This strategic move enhances SAX’s capabilities, deepens its client service offerings, and furthers its mission of providing expert guidance to business owners, entrepreneurs, and high-net-worth individuals.
Founded in 1989, MNK has earned a strong reputation for its client-first approach and internal growth, driven largely by referrals and a steadfast commitment to staff development. Over the past several decades, MNK has consistently expanded alongside its clients’ success, attracting top-tier talent and maintaining an unwavering focus on quality service.
The MNK acquisition marks the first transaction completed by SAX following its recent minority investment from Cobepa, an independent investment company with offices in Brussels and New York. This milestone underscores SAX’s strategic growth trajectory fueled by the Cobepa partnership, which is accelerating expansion across the East Coast, enhancing service capabilities, and fostering innovation while the firm remains proudly independent.
As a result of this integration, SAX now comprises 70 partners and 363 total employees, with a presence across five offices in New Jersey, New York, and Mumbai, India, and a remote workforce spanning 25 U.S. states.
“This acquisition represents a meeting of shared values – client dedication, integrity, and excellence,” said Joseph Damiano, CEO of SAX. “We are thrilled to welcome MNK into the SAX family. Their longstanding commitment to client success and internal growth is a natural complement to our vision as we continue to expand our footprint and capabilities. It’s also especially exciting to mark our first post-Cobepa transaction with a firm whose culture and approach align so perfectly with ours.”
Steve Nydick, Managing Partner of MNK, added: “For more than 35 years, we’ve taken pride in growing with our clients, fostering a team of professionals who care deeply about the work they do and the people they serve. Joining SAX allows us to enhance that mission with greater resources and reach, while maintaining the core values that have defined MNK since its founding.”
Michael Maddaloni, Managing Partner of MNK, commented: “Our partnership with SAX represents an exciting new chapter for our firm, our clients, and our people. Together, we can provide an even broader range of services and opportunities, while preserving the personal relationships and trust that have been the cornerstone of MNK for more than three decades.”
