24 Hour Fitness CEO Carl Liebert has added president to his title, one of several promotions the San Ramon, CA-based company announced today.

Since joining 24 Hour in 2006, Liebert has overseen operations of more than 400 clubs in the United States and Asia. Also during that time, the company has grown from 17,000 to 22,000 employees, and memberships have increased from 2.8 million to about 4 million, according to a company press release.

In other announcements, Jeff Boyer, who joined 24 Hour Fitness in 2008 as chief financial officer, has been named chief operating officer. Boyer will oversee U.S. field operations, fitness, marketing and business development. Boyer will serve a key role as the company aligns its corporate operations and initiatives with its field leadership team in hopes to drive growth and further expand profitability, according to the press release.

Patrick Flanagan is replacing Boyer as chief financial officer. Flanagan, who has more than 10 years of experience at 24 Hour, will oversee the accounting, treasury, tax, financial planning, strategy and internal audit functions for the company. Flanagan had served as the company’s senior vice president of finance and treasurer.

The interim label has been taken off the title for Chief Marketing Officer Bill Quinn, who had taken over as interim CMO in April after the departure of Tony Wells. Quinn will be responsible for all brand management, communications, marketing, Internet/mobile and member services support.

Jim McPhail, chief development and merchandising officer, will continue to oversee the company’s real estate and development strategy. McPhail, who has been with the company more than six years, has the added responsibilities of leading the company’s retail and merchandising functions.

“My leadership team has greatly contributed to the growth and development of 24 Hour Fitness, helping our company maintain its competitive advantage through club expansion while elevating brand awareness in communities across the country,” Liebert said in a statement. “I am proud to announce such well-deserved internal promotions and am fortunate to work with and lead such an exemplary group of leaders who understand how to deliver business results in a values-centered environment.”

All of the promotions went into effect June 1.

The announcements come as the company’s private-equity owner, Forstmann Little, faces a June 30 deadline regarding its sale. As The New York Times reported last year, Forstmann Little was contractually required to sell its three remaining assets—including 24 Hour Fitness—and return proceeds to its limited partners by the Saturday deadline. No information was provided by the company as to whether or not the deadline has been extended.

On Tuesday, 24 Hour announced its partnership with USA Basketball, which coincides with the company’s sponsorship of the United States Olympic Team.

For eight consecutive years, 24 Hour has been No. 1 on Club Industry’s Top 100 Clubs list. This year’s list will be published in the July issue.
