Chelsey is an avid gym-goer and has been addicted to group exercise since high school. A national tennis competitor as a teen, her athletic attentions turned towards fitness and group exercise when she hung up her tennis racket. Chelsey has been certified and teaching for over four years, and her classes always love her upbeat, motivating, and "boot camp" style of instruction. Now living in sunny California, Chelsey is happy to report that she is playing tennis again and starting to train for triathlons. In her other life, Chelsey is pursuing a PhD in Mechanical Engineering from Stanford University. Her focus is on cardiovascular tissue engineering, though she has also spent time working in the orthopaedic industry.
