Stonehenge Partners Announces Plans to Support Growing Anytime Fitness Franchise Organization
DDK Fitness, LLC to utilize investment for acquisition of NorCal Fitness, Inc., adding six clubs to its Anytime Fitness portfolio
FOR IMMEDIATE RELEASE: SAN DIEGO, Calif. — Sept. 17, 2026 — Today Stonehenge Partners (“Stonehenge”) and Woodbrook Lane Partners (“WLP”) announced their planned investment into DDK Fitness LLC (“DDK”), a leading Anytime Fitness (“AF”) franchisee serving the western U.S. Headquartered in San Diego, Calif., and founded in 2017 by CEO Dan Sussman and COO David Giesleman, DDK currently operates 20 AF locations across California, New Mexico, and Oregon.
Stonehenge and WLP’s investment will, in turn, help fund DDK’s acquisition of NorCal Fitness, Inc., one of the highest performing AF franchisees. The NorCal acquisition will add six gyms in California to the DDK portfolio: five in the northern part of the state and one in the southern.
Dan Sussman, CEO of DDK, stated, “This partnership with Stonehenge and WLP is a deliberate next step in our growth strategy, bringing together the capital and operating expertise to scale what we’ve built into one of the strongest platforms in the Anytime Fitness system. The Stonehenge and WLP teams share our long-term vision for the fitness business, and the acquisition of NorCal Fitness positions us to deepen our presence across California while continuing to raise the bar on the member experience.”
The acquisition combines two of the leading platforms in the AF system; both were finalists for “Multi-Club Operator of the Year” at the 2025 Anytime Fitness corporate convention. DDK has been a high-performing portfolio within the Anytime Fitness brand because of consistently strong membership results that reflect sustained growth and member satisfaction. It also maintains an active presence in their communities, with meaningful involvement that helps strengthen local engagement and brand trust.
Patrick Shevelson, Director at Stonehenge, said, “We are thrilled to partner with Dan and David. They’re exceptional operators, and we look forward to supporting their continued growth aspirations.”
Anytime Fitness has over 6,000 locations in more than 40 countries and on all seven continents, and prioritizes convenience, community, and personalized attention through training, nutrition and recovery. Gyms are accessible 24 hours a day, 365 days a year, and offer reciprocity; for the cost of one membership, members can work out at any AF all over the world.
“Anytime Fitness is proud to support franchisees like Dan and David who are investing in long-term growth within our system,” said Nick Herrild, Domestic Brand President, Anytime Fitness. “DDK has consistently demonstrated the operational excellence and community focus that define our brand. This partnership with Stonehenge and WLP reflects the strength and growth potential of the Anytime Fitness franchise model.”
