Bebashi Leadership

Sebrina Tate
Executive Director

With a Bachelor of Social Work degree from Temple University and an MSW from Howard University, Sebrina has nearly 25 years of experience as an administrator in various aspects of the social work field including Mental and Behavioral Health, Housing, Education, Social Services, and Community Relations. While working with a team of professionals to construct an Autism School in the greater NE, she decided to obtain a second master’s degree from Saint Joseph’s University in Criminal Justice with a concentration on Applied Behavior Analysis. Her experience includes the oversight of the Strength Alliance, a program that promotes and encourages resilience, health, and well-being of individuals who engage in organized commercial or underground sex work. She was also the primary evaluator for the Centers for Disease Control and Prevention grant awarded to the School district of Philadelphia for several years. This grant supported school-based HIV prevention and surveillance including the Youth Risk Behavioral Survey (YRBS) and School Health Profiles.

Sebrina comes to Bebashi after leaving her role as Director of Student Services at a small for-profit company that provides behavioral support to primarily autistic students throughout the state of Pennsylvania.
