After studying in the Film and Television program at the University of Oklahoma, Rachel Cannon left for Los Angeles in the hopes of landing a job in the business. She began finding acting jobs in 2005, first appearing on the sitcom "Cuts." The next year, she found herself on several different programs, such as the comedy series "Misconceptions" and "The New Adventures of Old Christine," as well as the forensic drama "CSI: Miami." She also landed in her first recurring roles that year on the supernatural series "Ghost Whisperer," playing a ghost named Amy Fields in three episodes, and in the sitcom "Campus Ladies," where she appeared in two episodes. Her next recurring role was in 2007 in the short-lived sitcom "I Hate My 30's," where she could be seen in three out of that show's eight episodes. Since then, she has had roles on programs like "The Big Bang Theory" in 2007, "Two and a Half Men," and "Wizards of Waverly Place." Her first big-screen credit was in the 2008 comedy "Smother," which starred Diane Keaton and Liv Tyler. She has also appeared in the 2009 comedy "The Alpha Geek," as well as in the made-for-TV movies "Reinventing the Wheelers" in 2007, and 2010's comedy "Open Books."
