Larissa Sethi
Owner And Head Coach
From the age of 9, I fell in love with gymnastics. My Dad used to say that if I wasn’t upside-down, something was wrong. Over the years, I competed in gymnastics, circus, and cheerleading events, with fitness becoming a huge part of my life. This spurred my passion for helping find ways to make fitness fun and achievable for all ages – and that love grew and transformed into CORE.
I’m excited to merge my expertise in Exercise Science and gymnastics to provide my community a safe space to explore fitness with our enthusiastic team. Here’s to making fitness FLIPPING FUN!
