DEERFIELD, Ill. — Walgreens has named Joseph Hartsig chief merchandising officer and Adam Holyk chief marketing officer.

Joseph Hartsig

Hartsig and Holyk report to Walgreens Boots Alliance Inc. (WBA) co-chief operating officer Alex Gourlay, and are part of the Walgreens Enterprise Operating Committee.

Hartsig also reports to Annie Murphy, WBA’s chief customer officer, while Holyk also reports to senior vice president and director of global consumer brands Andy Gibson.

Hartsig had been senior vice president of merchandising and omnichannel for Walgreens. In his new post, he continues to lead the merchandising team, which he has done since last August, and oversees digital commerce and mobile services, with a strategic focus on bolstering the retailer’s omnichannel ­capabilities.

Hartsig joined Walgreens in September 2015 as group vice president of merchandising strategic projects and has led the marketing, loyalty and digital commerce organizations. Before coming to Walgreens, he was chief merchandising and marketing officer for Essen-dant, a Fortune 500 wholesaler of business essentials, and senior vice president of merchandising at Sam’s Club.

Adam Holyk

Holyk is returning to Walgreens after serving as vice president of corporate strategy development at WBA since February 2015. He started his career at Walgreens in August 2011 as divisional vice president of customer loyalty and later became group vice president of customer insights. Prior to working at Walgreens, he held senior roles at market analytics specialist dunnhumby, working with Kroger Co., Macy’s Inc. and Shoppers Drug Mart, where he helped manage Canada’s leading retailer loyalty program.

With their appointments, Hartsig and Holyk take over for Linda Filler, who was president of retail products as well as chief merchandising and marketing officer before leaving WBA on April 1. While planning to devote more time to her family and to accept an offer to join the board of another publicly traded company, she has agreed to serve in an advisory role at WBA beyond that date. Walgreens did not identify the company.

Filler had begun at Walgreens as retail products president and chief merchant in January 2015. At the time she was also named to a leadership team that was immersed in the pending merger with Alliance Boots GmbH, a deal that Walgreens’ then-chief executive officer Greg Wasson said was made to create “the first global pharmacy-led health and well-being enterprise.”

Before coming to Walgreens, Filler spent 15 months as president of teen retailer Claire’s Stores Inc.
