CDI Corp. (NYSE: CDI) named David Arkless, a former ManpowerGroup Inc. (NYSE: MAN) executive as president, international. It also named former Sears executive Michael Castleman as executive VP, corporate development and operations, and it named another former Sears executive, Hugo Malan, as executive VP, president of staffing for North America.

The additions follow the appointment of CEO Scott Freidheim six weeks ago by the Philadelphia-based staffing provider. Friedman himself is a former Sears executive and had served as president of Kenmore, Craftsman and DieHard at Sears.

“These are high performance hires for CDI and signal the standard by which we will run the company,” said Freidheim. “Given an assessment of our company's talent and our aspirations toward value creation, there was an opportunity to enhance leadership in the areas of staffing, operating analytics, strategic thinking, acquisitions and partnerships, and geographic coverage outside of North America and the U.K. These accomplished executives were attracted to the opportunity to grow CDI and capitalize on our business opportunities.”

Arkless will be responsible for all international operations focusing on global business development for CDI. He spent more than 20 years with ManpowerGroup in strategic services, global account sales, global consulting, and corporate and government affairs, and was a member of the organization's global executive team. He has served as vice president of Ciett, the international confederation of private employment agencies, and helped develop inward investment strategies into China as vice president of the China International Council for the Development of Multi-National Corporations.

Castleman will lead enterprise analytics and performance optimization, as well as corporate development via partnerships, mergers and acquisitions. Castleman most recently was president of Kenmore, Craftsman and DieHard brands, after joining the company as CFO. Previously, Castleman founded or co-founded several investment firms, including Lehman Brothers Venture Partners, where he served as managing director and co-head.

Malan will run all of CDI’s North American staffing operations. He previously was president of fitness, sporting goods and toys business at Sears Holdings Corporation. Before that, he was managing director at Barclays Capital and Lehman Brothers. Malan also served as associate principal with McKinsey & Company, an information technology consultant, and researcher at Los Alamos National Laboratories.

In a separate story today, CDI announced third-quarter revenue rose by 6.4 percent.
