Theo Marshall was born and raised in and around Chicago, Illinois. As a young boy Theo moved often and attended several schools. Having grown up in a blue collar family and living in lower income neighborhoods in the shadows of Al Capone's old haunts, Theo was drawn to escape through sports and film. Moving and changing schools and neighborhoods allowed Theo to develop and learn to adapt and blend into any situation and role. After a turbulent high school journey both in and outside of the classroom, Theo would eventually be the first in his family to attend college receiving a Bachelor's Degree In Recreation, Parks, and Tourism, while also playing and earning a letter in N.C.A.A. College Football for Western Illinois University.
After College, Theo went to work in Chicago as a social worker for Adults with Disabilities and Mental Health Patients. After working in the Non-Profit sector as a Social Worker, Theo left for Ghana, West Africa as a Peace Corps Volunteer working on the H.I.V./A.I.D.S. Campaign and Education, while also building a community recourse center in Kaleo, Ghana: West Africa That amazing experience would forever change his life.
Upon returning from the Peace Corps, Theo rediscovered his love for Acting and Writing. Working as a Social Worker by day and performing on stages across the city of Chicago during the night, Theo was working and studying under such directors and as Clifford Morts, Michael Colucci, William Watt, Steve Walanka, Scott Rosengarden, Oksana Fedunyszyn, and Donte Orfei.
