Robert Graham has a new high-level executive.

Former Theory executive Andrew Berg has joined the men’s wear brand as president and will report to Michael Buckley, chief executive officer of Differential Brands Group Inc., which owns both Robert Graham and Hudson Jeans.

“With Andrew’s 20-year proven track record, we are confident that we have the leader in place to execute our premium omnichannel vision for the future,” said Buckley. “Under Andrew’s direction, we look forward to Robert Graham continuing to build brand awareness and maximize the explosive growth potential of its consumer direct channel, department store and specialty store relationships, as well as executing its playbook for international expansion.”

Buckley said it is “a pivotal time for our newly merged company” and it is essential for “an industry-leading merchant with experience driving growth to take the helm.”

Berg had served most recently as senior vice president of men’s wear for Theory, where he was responsible for overseeing the men’s wholesale, retail, e-commerce and international channels. During his tenure, he had launched new product categories including footwear, accessories, formalwear and Theory+.

Before Theory, Berg had worked at Ralph Lauren, Abercrombie & Fitch and Gap Inc.

“I believe Robert Graham is uniquely positioned to become one of the leading premium lifestyle brands, and I am thrilled to be joining the organization as president to spearhead the charge,” Berg said. “I am looking forward to working closely with the Robert Graham leadership team and the board of directors at Differential Brands Group in building this product-led brand.”

Differential Brands was officially formed in January when the merger of Hudson and Robert Graham was completed. It is a public company listed on the NASDAQ exchange.

Robert Graham was launched in 2001 by men’s wear designer Robert Stock and has been expanding its reach beyond its signature woven shirts into other categories including jeans and suits over the past several years. It operates 30 freestanding stores around the U.S.
