DRAPER, Utah — Sadler Gibb, a Utah-based public accounting firm, announced the acquisition of Assure CPA, LLC, a Spokane, Washington firm specializing in public-company audit and assurance. The acquisition, effective May 14, 2026, expands Sadler Gibb’s geographic reach into the Pacific Northwest and adds PCAOB-registered audit capability to its tax, audit, assurance, and advisory practices.
The combined firm will operate from offices in Draper, Utah and Spokane, Washington, serving growing businesses, complex organizations, and public companies across the western United States. The Spokane practice will operate under the Sadler Gibb name and continue from its current office at 7307 N. Division, Suite 222.
“Assure has built one of the strongest public-company niche audit practices in the Pacific Northwest, with rare technical depth in mining, natural resources, and manufacturing. Bringing their team into Sadler Gibb extends our regional footprint and meaningfully strengthens the technical bench we can put behind growth and serving clients across the West.“— Mark Elwood, Managing Partner, Sadler Gibb
Founded in 2020 as the public-company audit and SEC reporting practice spun out of DeCoria, Maichel & Teague, P.S. — a Spokane firm whose public-accounting heritage dates to 1997 — Assure CPA is PCAOB-registered and brings deep expertise in audit and assurance, SEC reporting, SOX 404 internal audit, tax, and advisory, with a particular focus on the mining, natural resources, and manufacturing industries. Six members of the Assure team will join Sadler Gibb, ensuring continuity for Spokane clients across audit, assurance, and advisory engagements.
Founder and Managing Director Jeff Maichel will retire in connection with the transaction. Mr. Maichel founded the predecessor firm in 1997 and brings 40 years of SEC reporting and public-company audit experience, with a particular focus on the mining, natural resources, and manufacturing sectors. He began his public accounting career with Coopers & Lybrand in Spokane and is a graduate of Montana State University. Over his career he built and mentored a team whose technical depth and long-standing client relationships will carry forward within Sadler Gibb.
“For nearly thirty years, our team’s focus has been on doing exceptional, high-integrity work for the public companies and industries we serve. Joining Sadler Gibb ensures our clients and our people are in outstanding hands — with a deeper bench and a broader set of services, while preserving the relationships and standards they’ve come to expect. I couldn’t have asked for a better next chapter for the team I’ve had the privilege to build.“— Jeff Maichel, Founding Partner and Managing Director, Assure CPA
Spokane clients will continue to work with their existing relationship leads and now gain access to Sadler Gibb’s expanded service lines, including specialty tax, attest, outsourced accounting, and advisory. Sadler Gibb clients in Utah benefit from added regional depth, a broader bench of professionals, and strengthened public-company audit capabilities.
