Katherine Mason’s SculptHouse Celebrates 10 Years with New Investment

The world’s first fitness studio to offer a Woodway Curve and Lagree Megaformer treadmill combination is set to expand.

Over the past decade, Katherine Mason estimates that she has helped tens of thousands of Buckhead residents achieve their fitness goals through her unique offering, SculptHouse. He says it’s the first fitness studio in the world to combine the Woodway Curve treadmill with the Lagree Megaformer, giving SculptHouse devotees a one-two punch of cardio and strength training.

SculptHouse offers two classes, both based on the Lagree Megaformer, a Pilates reformer-like piece of equipment that uses springs, pulleys, and moving carts to create a resistance-based workout. One is StrengthSculpt, a Megaformer resistance-based class true to the Lagree Fitness Method. The second is CardioSculpt, a 50-minute treadmill and Megaformer combination class. It’s the brand’s signature method, including the self-contained, low-impact Woodway Curve treadmill for a mix of cardio and strength training.

The business was a natural progression for Mason’s interest in sports, though he didn’t necessarily start a fitness empire. Mason, who grew up in Charlotte, was an athlete as a child, a passion he wants to tie into his professional career. After earning a degree in public relations from UGA, he moved to Atlanta, but didn’t like being alone in the corporate world. She quickly realized that 9-to-5 does not hold much appeal for her. “I have always been entrepreneurial and have an independent mindset. I come from a family of entrepreneurs,” he said.

Mason had been exposed to boutique fitness studios, a trend that disappeared when he graduated in the 2010s. Curious about the fitness industry, she chose to dive headfirst into finding a career there and moved to New York in 2013. “I wanted to learn, but I didn’t have a path when I got there,” she says.

During the two years he lived in New York City, he worked at Barry’s popular interval training studio and trained clients as a personal trainer at SLT, Lagree studio. Wilhelmina also signed her to their fitness model division. These three jobs lead Mason to his “aha!” moment The resistance-based strength training he loves at SLT and the cardio-focused training he loves at Barry can be combined — and no one else does. “It just hit me on the subway one day that this could be the most effective workout,” he says.

She realized she had a deep knowledge of athletic fashion from her days as a fitness model, working for niche brands, and wanted to bring that element into her studio. So in 2016, he opened his Buckhead location with a large retail footprint featuring advanced sports brands such as PE Nation and The Upside, as well as lifestyle brands such as Bala Bangles, Varley, and Arrae, among others, in 2016. A successful Dallas location followed in 2019.

Mason is renovating the Buckhead location in late 2025, gutting the retail side and adding upgraded lighting and new MegaPro machines in the fitness studio. As he began to think about how to start the next decade of the brand, he heard the news that Atlanta-based Jamie Weeks, once the largest franchisee of Orangetheory Fitness in the country, had created a new investment and operating company called Founder’s Row. The two, who had known each other for years, quickly reconnected, and the agreement to help SculptHouse create the next decade was made in early 2026 as a fitting anniversary gift for the brand.

Mason is still the majority owner (“I always will be,” he says), but Sunday’s new investment will allow him to expand thoughtfully to cities throughout the Southeast, such as Charlotte, Nashville, and South Florida. He also has his eye on a Midtown location. “SculptHouse was built on the belief that fitness and style should live under one roof, and this partnership gives us the opportunity to grow and evolve this brand into its next chapter,” she said.
