Born in Oklahoma, Taylor Mosby began acting in local theater at age six. By the time she had appeared in a few productions, teachers and directors were taking notice of the young actor's energy, presence, and keen sense of self awareness. Mosby soon began branching into on-camera work, appearing in a local commercial for natural gas, and when this proved to be a positive experience, her parents decided to take a trip to Los Angeles, where Mosby could audition for larger scale roles. After landing an appearance in the short film "Palms" (2012), Mosby was cast in the comedy "Cleaver Family Reunion" (2013), in addition to making some notable appearance on the series "The Middle" (ABC, 2009-2018) and "Twisted" (ABC Family, 2013-14). An even bigger role came for Mosby the following year, when she began playing the recurring character of Markayla Davis on the crime series "Criminal Minds" (CBS, 2005-). Taking each new opportunity in stride, Mosby took on a still more substantial part in 2017, co-starring opposite comedy great Tracy Morgan on the sitcom "The Last O.G." (TBS, 2017-).
