Mckesson Corp. announced on Nov. 1 that its venerated CEO John Hammergren will retire at the end of March 2019. Hammergren, who has been chief executive of the diversified healthcare supply, retail pharmacy and healthcare information technology company since 2001, presided over the rise of McKesson to a corporation that earned the No. 6 ranking in the Fortune 500 this year.
Hammergren hands the reins to Brian S. Tyler, who assumed the position of president and chief operating officer of the company just three months ago.
Tyler, however, is no stranger to McKesson, having held positions of increasing responsibility at the company since 1997. Prior to his appointment as COO, he was chairman of the management board at McKesson Europe.
The “chairman of the board” role will be handed over to the current lead independent director Edward Mueller, the former Qwest Communications chairman and CEO who has held the lead director spot since 2013.
Both Tyler and Mueller will assume their new positions immediately following Hammergren’s retirement on April 1.
