Sax, a Top 100 national accounting, tax, and advisory firm with a heavy presence in New Jersey, announced Wednesday the acquisition of Scheidel, Sullivan & Lanni CPA LLC (SSL) and Sierra Financial Advisors, LLC, effective Jan. 4.
The transaction integrates SSL’s decades of accounting expertise with Sierra’s fiduciary wealth management platform. Sierra will be absorbed into Sax Wealth Advisors, a move that pushes the subsidiary’s total assets under management (AUM) to over $4.5 billion.
The acquisition of Sierra Financial Advisors significantly bolsters Sax’s advisory capabilities. As of late 2025, Sax Wealth Advisors now oversees a massive portfolio, including approximately $1 billion in retirement plan assets.
The expanded wealth team, which now includes roughly 20 specialized Wealth Advisors, will focus on delivering comprehensive financial planning and investment management to a diverse client base of business owners and high-net-worth families.
With the addition of the SSL and Sierra teams, Sax’s total workforce has climbed to nearly 400 team members, led by 73 partners. While headquartered in Parsippany, the firm’s reach now spans:
-
East Coast Hubs: Offices in New Jersey, New York, and Pennsylvania.
-
Global Operations: A significant delivery center in Mumbai, India.
-
Remote Flexibility: A distributed workforce operating across 27 U.S. states.
“This acquisition reflects our commitment to strategic growth while upholding our values of excellence and stewardship,” Joseph Damiano, CEO of Sax said. “Their cultures align beautifully with ours, and we are excited to welcome their teams to the Sax family.”
