Meet Karen Boynton,
Owner/Master Instructor, Serenite’ Fitness featuring the
BarreAmped, BUTI yoga and Core Rhythm Methods

Karen’s love of dance and fitness has been a lifelong endeavor. Classically trained in Ballet, Tap, Jazz and Modern dance from the pre-school years through her college career, she has a true love of form and fluid movement. Later years found her fully committed to daily disciplines of aerobics and weight training to maintain a healthy and vibrant lifestyle. Karen is blessed to be a breast cancer survivor since 2008, and is actively involved in sharing her journey of survivorship with others through the Vanderbilt Hope Connection Program. “It is an honor to work with these courageous women, and assist them in their journey of healing and recovery…there is nothing more beautiful than a woman who’s spirit has risen above the life altering event of a cancer diagnosis….Serenite’ Fitness was born of my love of fitness and desire to help others achieve a healthy, and balanced lifestyle."
