Prior to receiving his master's degree, Josh received his BS in forensic science and BA in sociology from the University of Central Oklahoma, where he focused on behavioral sciences, becoming CPR-certified, and FEMA fire emergency certified.

Josh's intersectional identities and diverse and inclusive work put him on his path to not only fight for himself but the people around him and the Jewish State of Israel. Josh’s upbringing in a strong Jewish household and his personal and professional experience led him here, where he is empowered by educating the next generation on Israel. Josh dedicates his career to making Jewish people safer in this world and protecting the Jewish State.
