Private equity firm Silver Oak Services Partners LLC leads the recapitalization of Brilliant, a staffing firm targeting the accounting, finance and IT sectors. Management and co-investors also participated in the recapitalization of the Chicago-based firm.

As part of the transaction, Jeff Mariola will transition to CEO from president. Founder Jim Wong, who previously held the CEO role, will transition into a board of directors role.

Brilliant, founded in 2009, targets the Greater Chicago and South Florida markets. It is included on Staffing Industry Analysts’ list of fastest-growing US staffing firms.

“Brilliant has experienced great success and has been recognized regionally and nationally for our rapid growth, service quality and colleague engagement,” Mariola said. “We realized that to continue growing our business, we needed a strategic partner that shared our 2020 vision to continue to far outpace the industry in our core markets and expand into new markets over the next five years.”

Evanston, Ill.-based Silver Oak exclusively targets service businesses and invests in lower, middle-market companies, typically with EBITDA of $4 million to $20 million. In December, it sold Construction Labor Contractors LLC to Tradesmen International.
