Amid her high school career, Catherine Paiz landed her first modeling job with Victoria's Secret at the age of 16 and went on to model for Azzelia Swimwear in 2013, as well as several other brands. She also worked at an ice cream parlor before taking on a VIP manager gig at Arkadia Miami. "I've been working my whole life. I've always had a job since I was like 16. And I didn't go to college," she said, via The Netline. "I moved to China after high school and I was there for quite some time ... I came back and went straight to work. I moved to Miami and I managed a venue, and I worked at a hedge fund, and I've done like so many different things," she continued.

After meeting Austin McBroom in 2015, Catherine Paiz gave birth to their first child, daughter Elle, in 2016. Then, in 2018, the year she and McBroom secretly tied the knot, she welcomed her second daughter, Alaia. In 2020, McBroom and Paiz welcomed a third child, son Steel.
