Top 25 accounting firm Aprio announced its second deal this week, this time acquiring Waldron H. Rand & Co., a Dedham, MA-based firm with more than 110 years of history serving New England’s businesses and families, effective June 1.
Financial terms of the deal weren’t disclosed. A team of more than 70 Waldron Rand professionals and 12 partners are expected to join Aprio.
This is private equity-backed Aprio’s seventh M&A deal of 2026. Earlier this week, the Atlanta-based firm announced the acquisition of Isdaner & Co., a full-service accounting and advisory firm based in Bala Cynwyd, PA, effective June 1. The firm has also added two Oregon-based CPA firms (Delap LLP and Hoffman, Stewart & Schmidt PC), the SALT team from TaxOps in Denver, CAVU Advisors in Maryland, and Phoenix-based CPA firm Price Kong. In addition, Aprio launched Aprio Global in March to serve clients with cross-border tax, accounting, and advisory needs worldwide.

The Aprio/Waldron Rand deal brings expanded accounting, advisory, tax, wealth, and legal capabilities to Greater Boston, officials say.
“Waldron Rand was founded by the leaders who helped shape the accounting profession in the U.S., and they have spent over a century honoring that. We are proud that they chose Aprio to carry that legacy forward,” Aprio CEO Richard Kopelman said in a statement on June 4. “Together, we are bringing a new kind of firm to Greater Boston, one where clients experience accounting, advisory, audit, tax, wealth, and legal fully integrated into one team. Aprio is building this kind of firm across the Northeast, and Greater Boston is a cornerstone.”
Waldron Rand, one of the oldest ongoing public accounting firms in the U.S., was founded in 1912 by accounting pioneer Waldron H. Rand, a founding member and president of the Massachusetts Society of CPAs and of the American Institute of Accountants, the predecessor organization to the American Institute of CPAs.
Over more than a century, the firm has built a deeply respected practice serving closely held businesses, high-net-worth individuals, real estate investors, and nonprofit organizations across the region. That longevity reflects deep client service across real estate, estates and trusts, wealth planning, food manufacturing and distribution, and renewable energy.
“Joining Aprio is an incredible opportunity for our clients and team,” Rick Dlugasch, managing shareholder of Waldron Rand who is now a tax partner with Aprio, said in a statement. “Our talented team has built an incredibly special firm, and now they have access to resources, career paths, and opportunities that come with being part of a firm at Aprio’s scale. And for our clients, it means we can deliver expanded capabilities to help them grow. I’m excited about where we will go together.”
“Waldron Rand is entering its most exciting chapter yet. We are proud of the legacy we have built, including a leadership team comprised of a majority of women, a culture grounded in collaboration, and the deep trust our clients have placed in us across generations,” added Sharon Shaff, managing shareholder of Waldron Rand who is now a tax partner with Aprio. “Joining Aprio is the natural next step in our firm’s evolution—bringing greater resources and an even deeper commitment to the clients and communities we serve while preserving the relationships and values that have defined our firm for more than a century.”
The combination also includes Rand & Sweet, a client accounting services practice co-founded by Mike Sweet, that delivers technology-enabled accounting and advisory support to owner-managed businesses. The acquisition also brings in-house legal capabilities, led by Beth Grossman, CPA, Esq., through a separate alternative practice structure operating within the firm.
Aprio entered the Boston market in 2025 following the acquisition of Sandler & Co. in Needham Heights, MA.
