Aprio merges in Delap and Hoffman, Stewart & Schmidt

Aprio, a Top 25 Firm based in Atlanta, is expanding into the Pacific Northwest by adding two firms in the Portland, Oregon, area: Delap LLP and Hoffman, Stewart & Schmidt, P.C., effective Jan. 1, 2026.

The deal bolsters Aprio's auditing, tax planning, digital forensics and cybersecurity services. 

"Delap and HSS share Aprio's vision for helping clients navigate each stage of business growth," said Aprio CEO Richard Kopelman in a statement Wednesday. "Both firms bring exceptional talent, deep community roots, and specialized capabilities that complement Aprio's global platform. Together, we are creating something extraordinary and will deliver smarter solutions and greater value to clients at every stage of growth across the Pacific Northwest and beyond."

Financial terms of the deal were not disclosed. Aprio ranked No. 24 on Accounting Today's 2026 list of the Top 100 Firms, with $485.34 million in annual revenue, over 200 partners, more than 2,000 employees and 34 offices. A recent merger with Mize CPAs and its affiliated wealth management firm, Prism Financial Group, added 20 partners, over 300 professionals and two offices.

The deal with Delap will add another 117 professionals and 14 partners to Aprio. The firm, which dates back to 1933 and is based in Lake Oswego, Oregon, offers tax, assurance, business advisory and managed IT services, including cybersecurity and digital forensics. Delap also performs public company audits, mainly of financial institutions, and is registered with the Public Company Accounting Oversight Board. Delap CEO Earl Pierce, COO Ryan Boatsman and the entire group of partners are joining Aprio as partners. Delap ranked No. 25 on Accounting Today's Regional Leaders list of the Top Firms in the West, with $30.21 million in annual revenue.

HSS is a Portland-based CPA firm with more than 70 professionals and 10 partners. The firm, which was founded in 1979, provides tax, audit and advisory services, catering to clients in the construction industry, not-for-profit organizations, and closely held businesses. HSS managing partner Leah DiGregorio is joining Aprio as a partner, along with the rest of the partners at the firm.

Koltin Consulting Group CEO Allan Koltin advised Aprio and Delap on the deal, while Visionary Group president Bob Lewis advised Aprio and HSS. 

"This combination reflects a broader shift in the profession toward firms that can deliver both scale and specialized capabilities," Koltin said in a statement. "Delap's strong public company audit platform and technology-forward services align naturally with Aprio's national reach, creating a firm that is well positioned to support growing businesses facing increasing regulatory and operational complexity."

"The combination of HSS and Aprio creates a stronger platform for serving entrepreneurial and middle-market businesses in the Pacific Northwest," said Lewis in a statement. "Expanding Aprio's presence in the region enhances its ability to deliver consistent, high-quality service across markets as client needs become more complex and interconnected."

Aprio received a private equity investment in July 2024 from Charlesbank Capital Partners. In addition to the deal with Mize CPAs and Prism Financial Group last year, it acquired RSM US's Professional Services+ practice in the U.S. and Canada, JMS Advisory Group in Atlanta, and AI accounting assistant platform TimeCredit. The firm also announced plans last February to open a law firm in Arizona known as Aprio Legal LLC, in partnership with Radix Law.

Aprio has completed over 20 mergers and acquisitions since 2017, including Ridout Barrett & Co. CPAs & Advisors, Antares Group, Culotta, Scroggins, Hendricks & Gillespie, Aronson, Salver & Cook, Gomerdinger & Associates, Tobin & Collins, Squire + Lemkin, LBA Haynes Strand, Leaf Saltzman, RINA and Tarlow and Co.
