Atlanta-based IPA 100 firm Aprio (FY24 net revenue of $485.34 million) has announced its entry into the Pacific Northwest through combinations with Delap LLP and Hoffman Stewart & Schmidt PC (HSS), two firms based in the greater Portland, Ore. area. The combinations closed January 1.
Delap and HSS combined as Aprio creates a leading Pacific Northwest firm positioned to serve entrepreneurs and businesses navigating rapid growth, regulatory complexity and technological transformation. The expansion strengthens Aprio’s audit capabilities, including public company audits, advanced tax planning, digital forensics and cybersecurity, and comprehensive advisory services.
“Delap and HSS share Aprio’s vision for helping clients navigate each stage of business growth,” said Richard Kopelman, CEO of Aprio. “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.”
Founded in 1933 and headquartered in Lake Oswego, Ore., Delap LLP is a full-service accounting and advisory firm with 117 professionals and 14 partners. The firm provides tax, assurance, business advisory and managed IT services, including cybersecurity and digital forensics. The addition of Delap adds a financial institution-focused Public Company Accounting Oversight Board-registered practice to Aprio. Earl Pierce, CEO of Delap, Ryan Boatsman, COO, and the full Delap partner group have joined Aprio as partners.
HSS is a Portland-based CPA firm founded in 1979 with more than 70 professionals and 10 partners. The firm was named an Inside Public Accounting Best of the Best CPA Firm for 2025 and provides tax, audit and advisory services, with experience in construction, not-for-profit organizations and closely held businesses. Leah DiGregorio, managing partner of HSS, has joined Aprio as a partner along with the firm’s full partner group.
The expansion follows Aprio’s recent growth in Kansas and five additional new markets, furthering the firm’s strategy to expand in regions driving transformation and technological change. Aprio’s national footprint now spans major markets coast to coast.
Allan Koltin, CEO of Koltin Consulting Group, advised Aprio and Delap on the transaction. Bob Lewis, president of The Visionary Group, advised Aprio and HSS.
“This combination reflects a broader shift in the profession toward firms that can deliver both scale and specialized capabilities,” said Allan Koltin, CEO of Koltin Consulting Group. “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 Bob Lewis, president of The Visionary Group. “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.”
