Marion Campbell-Kammer was born and raised in Dayton, Ohio. She graduated Magna Cum Laude as a Drama major from Ohio University in 1999 and made the move and started working in Hollywood shortly thereafter. Looking for a job in the entertainment business she landed a job at a small agency and realized this is what she was meant to do. Some time later, a prominent casting director recommended she interview with Harry Gold at TalentWorks and she was hired on the spot. She has been an agent at TalentWorks since 2004.
