Hannah Jarman

Program Manager

Hannah Jarman is a Program Manager with Tulsa Changemakers. She moved from the south suburbs of Chicago to Tulsa, Oklahoma in 2017 with Teach for America to teach 6th and 7th grade social studies. Utilizing her degree in Global Studies (Conflict Resolution) and Communication from the University of Illinois at Urbana Champaign, Hannah became passionate about bringing current events and relevant history into her classroom for discussion. She quickly realized the impact student voice can have on building power in communities. Her motivation derives from the hope and passion she sees in students everyday to change the world as they (and we) know it.  Throughout her five years in the classroom, Hannah has coached debate, Changemakers, and other teachers. She is excited for the next big adventure.
