The Who What Wear Podcast: Jewelry Designer Jennifer Fisher on 20 Years of Her Brand, Current Best Sellers, and Expanding Her Empire

Andrea Beaty is an award-winning children’s author. Before she became known for her curious and clever characters in Rosie Revere, Engineer, and Ada Twist, Scientist, she was on track for a career in STEM. In college, Beaty studied biology and computer science, and then went on to work at a software company. Her start in writing came when she volunteered to write a tech support newsletter for a customer audience. The job helped Beaty hone her skills as a writer and copy editor years before she decided to try her hand at fiction. She started by writing stories inspired by the books she read to her kids before getting published in the 2000s. Since then, Beaty’s work has landed her on the New York Times Best Sellers list multiple times and has even been adapted into an award-winning Netflix animated series. She often credits her time as a technical writer as what gave her the skills to break down big concepts and life lessons for kids. Now, more than 20 years after her first book was written, Beaty shows no signs of slowing down with more stories on the way this year.

Leslie Tessler is the founder of Hanni, a bodycare brand that specializes in innovative, easy-to-use, ultra-hydrating products. Her first job was in fashion at Ralph Lauren before she pivoted into beauty as a marketing manager for L’Oréal Paris. She went on to continue her work at the executive level in the space with Dr. Dennis Gross Skincare. But after 10 years of working in such demanding roles, Tessler felt burned out. She booked a trip to Argentina to get away from it all, thinking she’d go back home in a few months, but she ended up falling in love with the culture and staying for a decade, during which she dreamed up the now-famous Hanni Weighted Razor and Shave Pillow. Leslie returned to the U.S. to officially launch Hanni in 2021, and her brand went on to become the first razor company to ever partner with Sephora in 2022. Today, it continues to expand the definition of bodycare with hit products that elevate everyday rituals.

Senada Greca is a celebrity personal trainer and serial entrepreneur in the health and fitness space. Although she found her love for fitness at a young age, she started her career in finance before pivoting into pharmaceutical and diagnostic sales. Working in the medical industry gave her a deep understanding of physiology that paired well with her love for strength training and exercise. When Greca began posting videos of her full-length workouts online, her platform quickly grew as more and more people looked to her for advice on how to achieve their fitness goals. It wasn’t long before Greca was training A-listers like Kim Kardashian. She then went on to found WeRise Fitness—an app where she helps millions of users build healthy lifestyles, and her newest venture has been co-founding science-backed supplement brand Aonic.
