# Shayla Cristie – Cal.com booking page > Hi! I'm an Integrative Health Practitioner and muscle tester. After years of unexplained symptoms and “normal” labs, muscle testing helped me finally understand what my body needed. Now I help others do the same in Austin and virtually. Your body is the expert. I’m the interpreter.
