Accounting and advisory firm SAX has acquired Scheidel, Sullivan & Lanni CPA LLC (SSL) and Sierra Financial Advisors, LLC (Sierra), according to an announcement made on January 8, 2026. As part of the deal, Sierra Financial Advisors becomes part of SAX Wealth Advisors, a subsidiary of SAX.
Joseph Damiano, CEO of SAX, commented on the acquisition: “This acquisition reflects our commitment to strategic growth while upholding our values of respect, integrity, commitment, excellence, and stewardship. Both SSL and Sierra have built strong legacies rooted in trusted relationships and professional excellence. Their cultures align beautifully with ours, and we are excited to welcome their teams to the SAX family.”
Leaders from SSL and Sierra—Timothy J. Sullivan, David F. Scheidel and Michael J. Lanni, Jr.—expressed support for the transaction in a joint statement: “This transaction ensures alignment with a firm that shares our culture, values, and dedication to clients. By joining SAX, we are providing our clients and team members with access to greater resources, expanded expertise, and increased opportunities—while maintaining continuity and the personalized service our clients rely on.”
With this acquisition completed at the end of 2026, SAX now has 73 partners and nearly 400 employees. The company’s reach includes offices along the East Coast as well as in India. Its workforce is also supported by remote staff across 27 states in the U.S.
The move marks SAX’s third major transaction since receiving a minority investment from Cobepa—a private investment firm—which has played a role in accelerating its expansion plans.
SAX Wealth Advisors’ national presence grows through this deal; as of December 30th, 2026 it employs about 20 wealth advisors managing more than $4.5 billion in assets—including approximately $1 billion in retirement plan assets. The addition of Sierra is expected to strengthen services such as financial planning and investment management for individuals as well as business clients.
