United Synagogue Youth: A conservative youth group for Jewish teens in grades 9-12. Jewish teens get to meet other Jewish teens from all over North America at conventions, go on summer programs, meet life long friends and have life changing experiences.
I went on a USY summer program and I'm still friends with everyone from my group, it's been 5 years.
USY has changed my life and made me a better person with all the repairing the world projects.
