CLINICAL SUPERVISOR, Elizabeth Chavez, M.S. 

My passion for helping others motivated me to pursue an education in Human Services. I received my BA from Cal State Dominguez Hills in 2018. Before graduating I got hired to work for an ABA agency as an in-home Behavioral Therapist. Being in the field for such a short amount of time made me realize I wanted to grow in the field, and I enrolled in a Graduate program with Purdue University. I earned my MS in Psychology with a concentration in ABA in 2020. I have been a Clinical Supervisor for nearly a year and it’s such a rewarding career as we help make a difference in individuals’ lives on a daily basis. My goal is to keep growing in the field; I am currently obtaining my hours to sit for the BCBA exam which I hope to take Fall 2021. I have worked with individuals from 3-35 years old. I have also worked with individuals with a variety of mental disorders such as Schizophrenia, Bipolar Disorder and Depression.
