Corey Waters

Corey started his academic career in the field of elementary education. He eventually changed his major to History. However, BA in History did not indicate stopping of his desire to teach and stay within education as a discipline.  

After college and successful employment at a daycare facility as a head teacher (school age program), Corey became passionate about moving forward with advancing his knowledge and carrier towards helping children of all abilities to learn and grow. It was here that he met the founders of ABASCT and began a career in the field of ABA. Since 2018 he has assisted numerous children with ASD and other challenges to lead more fulfilling, independent, and enjoyable lives. He went on to earn his RBT in 2020 and plans to earn his BCBA over the course of the next couple of years
