SAN RAMON, CA -- After sweeping changes were made in January at 24 Hour Fitness, including the departure of the company’s founder, Mark Mastrov, 24 Hour recently announced more personnel moves.

Jim Rowley, the north division president, resigned April 4 to pursue other opportunities, according to a company statement. Dan Benning, who had served as 24 Hour’s senior vice president of club operations and services, takes over as north division president.

The company's statement said, “Jim has made many contributions since joining the company in 1992 and will be missed by us all. 24 Hour Fitness thanks him for his leadership and partnership over the years, and we wish Jim the best in his future endeavors.”

Also, Chief Financial Officer Colin Heggie has been named president of California Fitness in Asia, reporting to CEO Carl Liebert. Heggie replaces Steve Clinefelter, who announced his retirement effective this summer and will return home to the United States with his family.

The new chief financial officer is Jeffrey Boyer, who joins 24 Hour from Michaels Stores Inc., where he served five years as president and chief financial officer. Prior to joining Michaels, Boyer held senior financial positions with a number of retailers and consumer product companies.

Tony Wells, who had served as 24 Hour’s senior vice president of marketing, has been promoted to chief marketing officer.

“We value the contributions of all our current and former team members,” Liebert said in a second statement from the company. “They have helped us build 24 Hour Fitness’ legacy as a fitness leader and innovator. We are confident that we have the right team in place to lead our company into an exciting new period of growth and success.”
