Kate made her small-screen debut with Season 1 of Breaking Amish, which premiered on Sept. 9, 2012, on TLC. She signed with Major Model Management NYC in 2012 and likely continued modeling for some time after leaving the show. 

Modeling allowed Kate to work closely with established fashion designers. Having gained some industry experience, she realized she was eager to push herself further creatively, as per HuffPost. 

"I always knew that I wanted to be a model but I never knew how excited and interested I was in design until I moved to NYC. Getting the opportunity to work with reputable designers in Manhattan and working with all the amazing prints and fabrics is so inspiring," Kate said.

"The designers have opened me up to a whole new world and everything they do is honestly a piece of art. It's working with such great people that has made me decide to design for the rest of my career," she added. 

Kate enrolled into Fashion Institute of Technology — the alma mater of Norma Kamali, Michael Kors, and many others — in 2015. Alongside her studies, she interned for leading firms like the Rosa Clara Group, Cynthia Rowley, and Jason Wu. 

Kate wasted no time in starting her own clothing brand. She launched Kate Stoltz NYC before concluding her studies in 2017. Her brand specializes in fashion-forward accessories, women's wear, cashmere products, and accessories for pets.
