Gilli Nissim

A Los Angeles native, Gilli started out performing in kids musical theater productions. Her improv career began with short-form improv during her 4 years at UC Santa Barbara. After earning a degree in Political Science with a minor in English, Gilli returned to LA and reemerged with many of her college improv alumni as part of the troupe Sticky Nights.


She has studied under UCB greats such as Ian Roberts, Alex Fernie, Eugene Cordero, Todd Fasen, Mike Leffingwell, Will McLaughlin, and Julie Brister. She has also studied at The Westside Comedy Theater and The Groundlings. Gilli was a member of the WCT House team Mad Hugs, and is incredibly stoked to be part of the UCB Harold team Winslow.
