Active Sports Clubs, Sausalito, CA, led by co-owner Jill Kinney, has purchased a majority of the assets of Club One Inc., San Francisco, the company she co-founded.

Terms of the deal, which was finalized on Monday and announced on Tuesday, were not disclosed. The deal includes all but one of the Club One Fitness health clubs in the San Francisco Bay Area and the majority of the fitness management agreements in the community center, hospital, corporate fitness and wellness management operations in the Club One asset portfolio.

The San Francisco Business Times reported Tuesday that Active Sports Clubs will take over 65 of the 85 Club One fitness centers that span 15 states.

The Bay Area health clubs will continue to operate under the Club One Fitness brand for a period of time, a spokesperson told Club Industry on Tuesday night, while a rebranding plan is in the works.

Active Sports Clubs will retain all of Club One's site-level employees, which equates to about 2,400 jobs. Active Sports Clubs also will assume about 145,000 members throughout the company.

Kinney formed Active Sports Clubs late last year with Bill McBride, former president and COO of Club One, which Kinney founded with her husband, John, in 1991.

"It's a little odd acquiring the company I founded," Kinney told the Business Times. "But I found an opportunity to step in and bring some improvements."

Kinney serves as chairman of Active Sports Clubs, McBride serves as president and CEO, and Carey White, who also worked at Club One, serves as CFO. All three, along with an investment group, own Active Sports Clubs. Robin Klaus remains the chairman and CEO of Club One Inc., a company spokesperson told Club Industry.

"Our model enables Active Sports Clubs to provide an enhanced, sophisticated and in many cases a technology-supported offering with a personalized touch," McBride said in a statement. "We're excited to unveil our improvement plans and a cadre of cutting-edge programs for our clients' choosing."

That includes the Itrim weight-loss center, which Kinney brought to the United States from Sweden and was incorporated into Active Sports Clubs' flagship location, a 40,000-square-foot club in Petaluma, CA, which the company took over on Jan. 1.

Kinney left Club One in 2007 to launch Clubsource, a development company specializing in community centers. McBride left Club One in July 2013 and formed BMC3, a consulting, coaching and club management company.

Club One was No. 16 on Club Industry's Top 100 Clubs list last year with a reported $80 million in 2012 revenue.
