SAN FRANCISCO — McKesson Corp. announced two key personnel moves, including the promotion of Chris Dimos to president of retail solutions for McKesson U.S. Pharmaceutical and Specialty Health.

Dimos will now oversee the Health Mart pharmacy network, taking over from Steve Courtman, who left the company to join health insurer Cigna as senior vice president of Cigna Pharmacy.

In his new role, Dimos is charged with driving the development of McKesson’s U.S. retail effort, including its pharmacy business, which besides Health Mart encompasses Access Health and McKesson’s consumer packaged goods team.

A pharmacy industry veteran, Dimos joined McKesson in September 2013 as senior vice president of corporate strategy and business development. Last year, he added marketing for the McKesson U.S. Pharmaceutical division to his ­responsibilities.

Dimos came to McKesson after seven years at Supervalu Inc., where he most recently served as president of Supervalu Pharmacies. Prior to that, he was vice president of pharmacy services at Albertsons Cos. from May 2002 to June 2006. He joined Albertsons Cos. after 10 years at American Stores, most recently serving as regional pharmacy ­manager.

Courtman had served as Health Mart president since joining McKesson in September 2012. He came to the company from pharmacy benefit manager Medco Health Solutions, where he was senior vice president of retail markets and had responsibility for contracting with independent and chain pharmacies and forming pharmacy networks for plan ­sponsors.

McKesson also announced that James Beer, executive vice president and chief financial officer, is leaving the company to become CFO of Atlassian, a San Francisco-based enterprise collaboration company in ­February.

With Beer’s departure, Britt Vitalone, senior vice president and CFO of McKesson U.S. Pharmaceutical and McKesson Specialty Health, has been promoted to executive vice president and CFO of McKesson Corp. Plans call for Beer to assist in a transition period into the early part of this year.

Beer has served as McKesson’s CFO since joining the company in October 2013 from security software provider ­Symantec Corp.

Under Beer’s leadership, the company expanded its retail presence, grew its specialty drug capabilities, enhanced its technology offerings and formed Change Healthcare, among other achievements.

“James has been a wonderful colleague and friend. I admire his financial discipline and management and commitment to our company’s shared values,” McKesson chairman and chief executive officer John Hammergren said. “We wish James well as he pursues his next ­opportunity.”

Vitalone came to McKesson in February 2006. Before his current role, he served as senior vice president of corporate financial planning and analysis and mergers and acquisitions finance and as senior vice president and CFO of McKesson Medical-Surgical.

“For more than a decade, Britt has demonstrated an outstanding track record of performance in various finance and operational roles across multiple businesses at McKesson. The board of directors, executive committee and I are excited to appoint Britt,” Hammergren said. “We are confident that Britt’s deep financial experience and knowledge about our businesses will serve us well as we build upon McKesson‘s successes and position the company for future growth.”
