Theo Caesar is the head of 90210 Talent Agency and the Agency's primary Theatrical Agent. He joined the agency as a talent rep in 2009.

Theo's journey into the entertainment industry began at the age of 12 when he became a child actor and landed a role in "Police Academy 3: Back In Traning". The South Bronx, NY native went on to star in several film, television, print and theater productions from New York to California and even Canada. At the age of 16, his family relocated to Virginia Beach, VA. He took up an interest in music and began interning at a recording studio called "TMH (The Music House)". Before long, the studio owner, David Velazquez, taught Theo how to engineer and produce recordings of his own, making him the head engineer and business manager of the studio. In his early twenties, he entered into a business partnership with David and they began a production company called "QSL Entertainmentt". Theo started a hip hop group named "Black Reign" with his friends Shante "L.U.V." Holland and Donshay "Big Qweezy" Gregory. Over time, Velazquez decided to take a different direction in business and turned over the majority of his interest in QSL and TMH over to the trio. They went on to sell thousands of CDs throughout the East Coast and perform regularly over a ten year span which even led them to win the 2005 Blendzville Award for Best Independent Label in Hampton Roads, VA.
