As a child, Shelby Kremin struggled in school as a result of her anxiety, learning disabilities, and frequent sinus infections. Shelby only found relief after learning about Crossinology, a technique that employs applied kinesiology and acupressure to reprogram the brain. This discovery prompted her to open Chicago Brain and Body Connection, where she provides Crossinology in various forms. Some treatments focus on allergy relief or muscle reactivation, while others work to help those with ADD or dyslexia. To round out her offerings, Shelby also offers holistic services, such as chakra and meridian balances.
