Brandie- Skills coach, Registered behavior technician

My name is Brandie Thurston. My interest in working with the special needs community started when I was in high school. I participated in the partners club, a club where peers get together with the students in special education classes and do extracurricular activities together (such as attend football games, put on plays, go bowling, etc.). During high school, I also got my license as a Board Certified Cosmetologist. Upon graduating, I started working at a salon and soon after, I began interning at a private school for children with special needs. Because of my experience in both the special needs field and hair care, I do provide hair cutting services for some of the children and adults I work with. After nine years of experience, I found myself working with Mountainside ABA and I am now a Registered Behavior Technician. I fell in love with helping children thrive in the community, improving their behavior and growing academically and, I continue to have the same passion for my clients with Mountainside ABA.
