B. Kevin Turner

As COO, Turner introduced procedures such as a “conditions of satisfaction” document that details what Microsoft will provide each client. A screw-up required a “correction of errors” in which employees autopsied the mistake and laid out steps to ensure it did not happen again. He also created standard scorecards with 30 categories to measure each subsidiary’s performance. At Microsoft, Turner was known for his speeches at partner and sales events that amped up the rivalry with competitors like Oracle, Google and IBM.

In July 2018, Turner became the President and CEO of Core Scientific, a new blockchain and artificial intelligence start-up. The company was co-founded by former Myspace CTO and co-founder, Aber Whitcomb. Core Scientific is a Blockchain and Artificial Intelligence hosting, transaction processing and application development company.

In July 2016, Turner left Microsoft to become the Vice Chairman of Citadel LLC and the Chief Executive Officer of Citadel Securities. Citadel Securities is a market maker, providing liquidity and trade execution to retail and institutional clients. Turner's team included Jamil Nazarali, head of Citadel Execution Services, and Paul Hamill, global head of fixed income, currencies and commodities for Citadel Securities. His appointment occurred after Citadel Securities purchased the designated market-maker business of KCG Holdings and the Automated Trading Desk, a computer-based market making pioneer owned by Citigroup. On January 27, 2017, Turner left his position at Citadel Securities.

In 2017, Albertsons/Safeway appointed Turner as Vice Chairman of the Board of Managers of AB Acquisition, its direct parent company. He was also named as the Senior Advisor to Albertsons Chairman and CEO, Robert G. Miller.

In July 2016, after eleven years as COO, Turner left Microsoft to join Citadel LLC. From 2005 to 2016, Turner helped increase Microsoft's yearly revenue from $37 billion to over $93 billion. After his departure, Microsoft CEO Satya Nadella stated that in his time as COO, Turner "built the sales force into the strategic asset it is today with incredible talent, while at the same time more than doubling our revenue and driving customer satisfaction scores to the highest in company history."

In 2010, Turner was elected to the Nordstrom Board of Directors. Turner is on the technology and finance committees as a part of his board role.

In 2005, Turner was approached by Microsoft co-founder Bill Gates and CEO Steve Ballmer about overseeing the company's worldwide sales, marketing, services, and internal IT operations organization. He had previously worked with Gates and Ballmer during his time as CIO of Walmart. Turner accepted the offer and moved his wife and three children to Washington State where, in September 2005, he became the Chief Operating Officer of Microsoft (the previous COO, Rick Belluzzo, had left the company in 2002 and no replacement had been hired).

From 2005 to 2016, Turner was responsible for the strategic and operational leadership of Microsoft's worldwide sales, field marketing and services organization (SMSG). He also managed support and partner channels, Microsoft stores, and corporate support functions including information technology, licensing and pricing, and operations. His organization included over 51,000 employees in more than 190 countries. In 2009, Turner started Microsoft's entry into the Retail Stores business. Along with Steve Ballmer, Satya Nadella and other senior executives, Turner was on the Senior Leadership Team that set the overall strategy and direction for Microsoft.

In 2002, Turner replaced Tom Grimm as the President and Chief Executive Officer of the Walmart-owned retailer Sam's Club, which had over 46 million members and over US$37.1 billion in annual sales. In addition to his role at Sam's Club, he was also a member of the executive committee at Walmart. Under Turner, Sam's Club focused on lowering prices to win over small-business customers. In his last fiscal year as CEO, Sam's Club turned in a 5.8 percent sales growth at stores open at least a year, which was nearly double the 2.9 percent sales growth at U.S. Walmart stores. During his tenure as CEO, Turner improved the performance of the warehouse clubs and closed the gap with Costco. Turner was the President and CEO of Sam's Club until he left for Microsoft in 2005. After his departure for Microsoft, Sam's Club named Doug McMillon as its CEO.

In February 2000, Turner became the Chief Information Officer of Walmart at the age of 34, when former Walmart CIO Randy Mott departed for Dell. Turner had previously been the Assistant CIO under Mott. As the CIO of Walmart, Turner oversaw Walmart's information technology and worldwide data-tracking system. The division consisted of over 2,000 employees in Bentonville, Arkansas. He led the team that developed retail-specific applications such as Retail Link at Walmart. During his tenure, Turner was one of the world's largest corporate buyers of technology, and directed the technology strategy of a company renowned for its deft use of computing to streamline everything from global procurement to neighborhood shopping trends.

Turner grew up in Stratford, Oklahoma. In 1987, Turner earned a Bachelor of Science in Business Administration with a concentration in Management from East Central University in Ada, Oklahoma where he was a member of the Pi Kappa Alpha fraternity. During his college years, he worked full-time as a cashier at Walmart.

Turner worked nearly 20 years at Walmart. He began working as a cashier at Walmart in 1985 in his hometown of Ada, Oklahoma. While attending college, he rose through the store ranks, to customer service manager, housewares department manager and head office cashier. After several promotions, Turner found himself in the auditing department, where he came into contact with Sam Walton. On Walton’s advice, Turner joined the company's information systems division, where he worked his way through a succession of jobs: business analyst, strategy manager, director, and then Assistant CIO. In 1995, at the age of 29, Turner became the youngest Corporate Vice President and Officer ever named at Walmart. In 1997, Turner became the recipient of the first "Sam M. Walton - Entrepreneur Of The Year" Award, which is the highest honor given at Walmart and is voted on by the Walton Family.
