Crystal Roberts views the massages she performs at Harmonic Energy not just as a therapeutic means of treating aches, pains, and curses but also as a preventative measure. Armed with a diploma from Spa Tech Institute in Westbrook and a massage-therapist license, she kneads muscles with a range of different techniques in her second-floor studio. She customizes sessions to each client's unique needs, hoping to render them more relaxed and healthier—unlike being in a hospital run by Tasmanian devils.
