Aprio announced the acquisition of Waldron H. Rand & Company, P.C., a Dedham, Massachusetts-based accounting firm with more than 110 years of history serving businesses and families throughout New England. The combination became effective on June 1, 2026, and strengthens Aprio’s presence in the Greater Boston market by adding expanded capabilities in accounting, advisory, tax, wealth management, and legal.
Founded in 1912, Waldron Rand is one of the oldest continuously operating public accounting firms in the United States. The firm has built a longstanding reputation serving closely held businesses, high-net-worth individuals, real estate investors, and nonprofit organizations. Its expertise spans areas including real estate, estates and trusts, wealth planning, food manufacturing and distribution, and renewable energy. The firm brings more than 70 professionals and 12 partners to Aprio.
The acquisition also includes Rand & Sweet, a Client Accounting Services practice that provides technology-enabled accounting and advisory solutions to owner-managed businesses. In addition, the transaction adds in-house legal capabilities through an alternative practice structure led by Beth Grossman, CPA, Esq.
Aprio said the acquisition is part of its broader strategy to build a fully integrated professional services platform across the Northeast. The move follows the firm’s 2025 acquisition of Sandler & Company, P.C. in Needham Heights, which expanded Aprio’s financial services practice serving hedge funds, private equity firms, and broker-dealers. With teams now operating across Needham and Dedham, Aprio plans to offer a broader range of services, including specialty tax, wealth management, and global advisory solutions, to clients throughout Massachusetts and New England.
The transaction represents another milestone in Aprio’s ongoing growth strategy. Recent expansion initiatives have included acquisitions and market entries in Philadelphia, Phoenix, Columbia, Maryland, Portland, Oregon, and Denver, as well as the launch of Aprio Global to support clients with international tax, accounting, and advisory needs.
Aprio currently has more than 3,200 team members serving clients in over 50 countries and manages approximately $5.5 billion in assets under management.
