Atlanta-based IPA 400 firm CKH Group (FY25 net revenue of $15.2 million) acquired the Michigan audit practice of Jason F. Clausen, expanding its audit practice and capabilities in commercial and nonprofit assurance services.

As part of the acquisition, Jason Clausen joins CKH Group as audit director and Greg Silos joins as audit manager. Seven additional professionals will also join CKH Group, bringing the total incoming team to nine.

The addition expands CKH Group’s capabilities in Professional Employer Organization (PEO) audits, Service Organization Control (SOC) reporting, peer reviews and nonprofit audits. 

“Jason and his team have built an outstanding reputation for quality and client service, making them a natural fit for CKH Group,” said Nick Catrakilis, executive chairman of CKH Group. “We’re excited to welcome them and continue investing in the growth of our audit practice.”

Clausen said the firms share a commitment to high-quality service and long-term client relationships.

“When looking at the future of my firm, I wanted to find a group that shares our commitment to delivering high-quality service and building long-term client relationships,” he said. “CKH Group was the clear choice. I’m excited to continue serving our clients while providing them access to the broader resources and capabilities of the CKH Group team.”

The existing engagement team will remain in place, with clients continuing to work with their current professionals. They will also gain access to CKH Group’s broader audit, tax, accounting and advisory services.
