A phenomenal improviser and a rising stand-up, Ratner won California's Funniest Female Contest at Flapper’s Comedy Club in Burbank in June of 2012.

Analytic and psychologically astute, Shelagh Ratner takes American culture to its absurd limits with deft riffs on:
Nicole Richie: author. The end of civilization?
The perils of a winner-eats-all combination of Biggest Loser and Survivor in which the fattest person is eaten on an island on the season finale.
McDonald’s cashing in on obesity with the McTrough.

Ratner's sharp, brainy comments are tempered by her warm connection to the audience. Based in Los Angeles, she appears at The Improv and The Comedy Store. Further afield, check out her fashion spoofs in Life and Style's "Style Slip-ups," as well as her VO copy in Glamour's "Gift Of The Week" on YouTube.

She wrote, directed and starred in We Got Spirit, an all-improvised mockumentary inspired by NFL cheerleaders and featuring Jennifer Coolidge.

Ratner was the voice of AT&T Wireless for 8 years and gives frequent talks to aspiring voice-over actors.

Appearances include VH1's Total Access and Lifetime's Prank My Mom and Prank My Kid, TV Guide Channel's Stand Up In Stilettos, and NuvoTV’s Stand Up And Deliver.

Shelagh Ratner trained at Groundlings East and she participated in several improv and sketch groups. Ratner contributed to Stories at the Moth where, given situation and characters, she incorporated highlights of every story told into an entirely improvised finale.

An unusually mobile childhood and youth (eleven moves before college, to and from Europe, South America and the East and West coast) shaped Ratner's novel perspective on Stateside life. She relaxes with math histories and biographies but has yet to work Paul Erdos into her act.
