WESTBOROUGH, Mass. — BJ’s Wholesale Club Inc. has promoted Lee Delaney to president.

Delaney had been serving as the company’s chief commercial officer. He will continue to report to chairman and chief executive officer Christopher Baldwin, who relinquished the president’s title to Delaney last month.

The warehouse club has been expanding into new markets and investing to make shopping more convenient for members as part of a transformation plan launched in 2016.

“We have great opportunities ahead of us, and I’m thrilled to lead a strong team as we execute our strategic priorities,” Delaney said in a statement. “The new structure will enable us to create a seamless membership experience from acquisition to renewal while providing the outstanding value and service that members expect from BJ’s Wholesale Club. I look forward to building on our momentum as we continue our transformation.”

Delaney joined BJ’s in May 2016 as executive vice president and chief growth officer. He was named chief commercial officer in February 2018. Delaney previously was a partner at the Boston office of Bain & Co., where he was a leader in the firm’s consumer products practice.

“Lee’s strategic vision and leadership have been instrumental in transforming BJ’s Wholesale Club,” Baldwin said in announcing Delaney’s promotion. “We are creating a focused commercial organization that will provide outstanding member service by delivering great products at unbeatable value. Under Lee’s leadership, the new organization will build on our progress as we continue our transformation, driving long-term, profitable growth.”

BJ’s opened its latest location, in Clearwater, Fla., in April. It has 217 warehouse clubs and 138 BJ’s Gas outlets, mostly on the East Coast but also in Pennsylvania and Ohio.
