SAX Advisory Group (“SAX”) has been ranked #24 among the nation’s fastest-growing accounting firms in Accounting Today’s 2026 Top 100 Firms report, the profession’s leading trade publication. The ranking marks the latest milestone in an ongoing expansion that has reshaped the firm’s scale and service capabilities.

- #24 among the nation’s fastest-growing firms

Two things are driving that growth: a fast-expanding Client Accounting Services practice and an active acquisition strategy that has added three firms in 2026 alone.
Leading the Shift Toward Advisory and CAS
One driver of that growth is SAX’s Client Accounting Services (CAS) practice, the firm’s fastest-growing practice area. As a shrinking pool of accounting professionals has made outsourcing the accounting function less of a luxury and more of a necessity, SAX has turned that industry pressure into a strategic opportunity. Peter Motsch, Partner and Head of SAX’s CAS Practice, was featured in Accounting Today’s spotlight on the rise of CAS across the profession. The message is consistent: compliance is table stakes, and the firms pulling ahead are the ones that can sit at the leadership table.
Scaling Through Strategic M&A
The second driver is an active acquisition strategy. SAX was recognized in Accounting Today’s 2026 Top Highlights for its 2025 acquisition activity, and that pace has accelerated: the firm has completed three acquisitions in 2026 alone, five since receiving a minority investment from Cobepa in July 2025.
That investment was structured specifically to fund growth while keeping SAX independent, which means the client relationships and team continuity that defined the firm before the investment remain intact.
Additional detail on SAX’s 2025 acquisition activity and platform expansion is available in the firm’s 2025 Year in Review.
“We’re entrepreneurs first, accountants second. That’s not a tagline, it’s how we’ve been purposely built. We put CAS, wealth management, technology, and advisory under one roof because our clients shouldn’t have to coordinate five advisors to get one answer. Our growth reflects that. We’re building something our clients can grow into,” said Joseph Damiano, CEO of SAX Advisory Group.
Damiano continued: “We brought in a capital partner specifically so we could stay independent and keep growing on our terms. We know where client needs are heading and we’re building ahead of them.”
Building a Modern Advisory Platform
SAX’s expansion reflects broader shifts reshaping the accounting profession. As mid-market companies demand more from a single relationship, the firms pulling ahead are redefining what an accounting firm can be. SAX is building toward that model: a modern advisory platform where compliance is the foundation, not the ceiling.
