At five feet three inches, Sue Costello may look harmless, but once she opens her mouth, it is obvious that this blonde means business - funny business. Sue has the ability to bring a room full of patrons to tears with her comedic disposition and vivacious wit. That mixed with her vulnerability and honesty has made her one of the only women in the business who can do what she does.

From her thick Boston accent to her street-smart demeanor to her ability to make you feel like you want to take care of her and be her best friend, Sue has the "it" factor. After 3 years of theatre arts training at the University of Massachusetts, Sue began her career as a stand-up comedian in Boston, later relocating to the bustling city of Manhattan.

Since that time, she has appeared on several television shows such as "NYPD Blue" and "Tough Crowd" with Colin Quinn on Comedy Central. After starring in two TV pilots for CBS, Sue earned her very own self-titled television series, "Costello." Sue was also a producer and the co-creator of the show. Though "Costello" lived a short life on air, Sue received various accolades for her energetic wit. Sue was a guest host on NBC's "Later." She has also performed on Comedy Central's "Premium Blend." In addition to television appearances, Sue has also honed her performing skills on the stage and the big screen. Sue was cast in such films as "Southie" starring Donnie Wahlberg and directed by John Shea, "Once in the Life" with Laurence Fishburne and "The Fighter" with Christian Bale.

Sue's already extensive resume continues to grow -- she performed with Rosie Perez, Alan Cumming and Olympia Dukakis at the Nantucket Film Festival's Storytelling event and co-starred in Jim Breuer's pilot for Comedy Central. Her stand up reached a new level when she made it to the finals of NBC's Last Comic Standing. Sue has also been a regular guest host on "Breuer Unleashed" on Sirius radio. She is currently performing her one-woman show, "I Wasn't Trying To Be Funny" (see calendar for details).
