Two St. Louis Accounting Firms Merge with Purk & Associates, P.C.

Purk expands senior management team with Doug Pleus, CPA, Pleus & Company, LLC; Terry Knox, CPA, Dwyer Costello and Knox P.C.; Holly Breuer, CPA, and Candice Carter

St. Louis (February 16, 2021) – Purk & Associates, P.C., the leading, woman-owned St. Louis-based accounting, and management advisory firm, announced today that Pleus & Company, LLC; and Dwyer Costello and Knox P.C. have merged with them.

Doug Pleus, CPA, former owner of Pleus & Company, and Terry Knox, CPA, former partner at Dwyer Costello and Knox, join the firm’s senior management team.

“I’ve known Doug and Terry for years, and I have great admiration for their talents and the accounting firms they founded. When we started talking separately about merging firms, it was because each firm had unique strengths, similar core values, and strong client relationships. It all came together at the end of 2020 to merge their firms with Purk” said Jennah Purk, CPA, President and Co-Founding Shareholder, Purk & Associates.

Also, Purk hired Holly Breuer, CPA, as a Principal and Chief Operating Officer, and Candice Carter as a Director.

“I have known and worked with Holly and Candice for more than two decades. We are fortunate to have such talented, dedicated and energetic professionals join our team,” added Purk.

Because of the mergers and addition of talent, Purk & Associates estimates that 2021 revenue is on track to be $5 million, nearly $2 million more than 2020 revenues.
