Her journey into comedy began when she moved to Los Angeles at the age of 25 and joined the famed comedy troupe The Groundlings. Her big break came when SNL producers attended a Groundlings performance and invited her to audition.

She was hired as part of an almost entirely new cast in 1995, which included fellow Groundlings members Will Ferrell and Chris Kattan.

After leaving SNL in 2000, she continued to work in television and film. She appeared in movies such as "Scary Movie," "Inspector Gadget," "Liar Liar," "Dumb and Dumberer: When Harry Met Lloyd," "Shrek the Third," and "Southland Tales."

She also made guest appearances on various TV shows, including "Just Shoot Me!," "Strangers with Candy," "Curb Your Enthusiasm," and "Ally McBeal."

Her personal life has been relatively private. She was raised in Upper Darby alongside her siblings Brian, Tommi Jr., and Denise. Her parents, Patricia Breen Oteri and Gaetano Thomas Oteri, were supportive of her career. 

Her father was the founder and former CEO of the music publishing company Of Music. Oteri has not publicly disclosed details about her romantic relationships or family life, preferring to keep her personal matters out of the spotlight.
