SAX Makes Major Acquisition

On Jan 8, 2026

Accounting, tax and advisory firm SAX has acquired Scheidel, Sullivan & Lanni CPA LLC (SSL), along with Sierra Financial Advisors, LLC (Sierra).  As part of the transaction, Sierra Financial Advisors, the firm’s wealth management arm, has been acquired by SAX Wealth Advisors, a wholly owned subsidiary of SAX. The transaction further strengthens SAX’s integrated tax, accounting, advisory, and wealth management platform and reflects the firm’s continued investment in long-term, client-focused growth.

“This acquisition reflects our commitment to strategic growth while upholding our values of respect, integrity, commitment, excellence, and stewardship,” said Joseph Damiano, CEO of SAX. “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.”

In a joint statement, leaders of SSL and Sierra, Timothy J. Sullivan, David F. Scheidel and Michael J. Lanni, Jr. shared their enthusiasm: “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.”

This transaction brings SAX to 73 partners, and close to 400 team members, and a national and international presence, including offices all along the East Coast and India, supported by a remote workforce spanning 27 US states. It also represents the third transaction since SAX’s recent minority investment from Cobepa, an independent investment company accelerating SAX’s strategic expansion, capabilities, and innovation.

Through the acquisition of Sierra Financial Advisors, SAX Wealth Advisors expands its national wealth management footprint, bringing its total as of 12/30/2026 to approximately 20 Wealth Advisors and more than $4.5 billion in assets under management, including approximately $1 billion in retirement plan assets. The addition of Sierra further enhances SAX Wealth Advisors’ ability to deliver comprehensive financial planning, investment management, and fiduciary advisory services to individuals, families, business owners, and retirement plan sponsors.
