Before graduating with his Bachelor’s degree, Justin served as a legislative aide for Texas Senator John Whitmire, representing the 15th Senatorial District comprised of north Houston and parts of Harris County. It was here that Justin acquired an interest in the law and public policy.

After university, Justin worked as a Court Clerk for the 200th District Court of Travis County, Texas, which was at the time presided over by Third Court of Appeals Justice Gisela Triana. It was there that Justin honed his knowledge of the judiciary and legal applications.
