Mark Walchirk has resigned as chief executive of Patterson Cos. after a board investigation determined he "violated company policy and demonstrated poor judgment regarding an encounter with an employee."
The resignation was announced last week and effective immediately. Don Zurbay, the company's chief financial officer, was named president and CEO.
"Patterson is committed to cultivating a people-first culture where every employee is treated with respect and those standards apply to every member of the organization," board Chair John Buck said in a news release. "Immediately upon becoming aware of the allegation, the independent directors conducted a comprehensive investigation with the support of independent, outside legal counsel and determined that Mark could not remain in his leadership position."
Zurbay joined Patterson in June 2018. He was previously a vice president and CFO at St. Jude Medical Inc. before that company was acquired by Abbott Laboratories.
"I'm excited to continue to work closely with the board and the rest of the management team in my new role to build on our strong momentum and capitalize on the many opportunities ahead," Zurbay said in the release.
Patterson's controller and vice president of finance, Kevin Barry, was named interim CFO.
The company said in a related Securities and Exchange Commission filing that Walchirk's actions "did not relate to the company's operations or the integrity of the company's financial statements."
A spokesperson for Patterson had no additional comment on the violations or the board investigation. Walchirk could not be reached for comment.
