During her last undergraduate year, she did an internship with Brain Fitness Club, which was an organization open to people with Alzheimer’s, Lou Gehrig’s disease and Parkinson’s. However, it wasn’t until her volunteer time with Nemours Rehabilitation Department that she realized she had a passion for helping children. After graduation, a colleague steered her toward the field of ABA. Grisellys began working as a Behavior Assistant in an ABA company where she became a Registered Behavior Technician.
