Marc Grondahl, who originally co-founded Planet Fitness with his brother and CEO Michael Grondahl, has been named chairman of the company’s board of directors.
Grondahl, 44, had worked as Planet Fitness’ CFO until April, when Jayne Conway took over that role.
Planet Fitness consisted of four gyms in New Hampshire when it began franchising in 2003. Today, the company now has 350 locations in 36 states.
“I think Planet Fitness is in a great position right now,” Marc Grondahl said. “We have the management, infrastructure, and, of course the business model to become the leader in the industry. I look forward to helping it continue to grow.”
Known for its relaxed Judgement Free Zone® atmosphere and friendly prices, Planet Fitness boasts 2.3 million members nationwide and is ranked by Inc. magazine as one of the fastest-growing private businesses in America.
“Marc’s tremendous vision has always been a key to our growth, and we want to retain that for the long term,” Michael Grondahl said in a statement. “His financial expertise and steady hand guided us through the challenges of our early days, and he laid the groundwork and helped establish the culture that’s put us where we are now.”
