Greg & Friends create improv comedy shows around the Bay Area, particularly in the south bay. Greg pulls awesome improvisors and improv groups from around the bay to perform together in a huge variety of styles from short form to long form, improvised musicals, and even Henson-style puppet improv. Guest improv groups have included Stanford Improvisors (SIMPS), Rag Tag improv, Flash Forward Improv, and performers from the Broadway cast of Avenue Q!

Greg & Friends had a monthly show in the 2023-2024 season of the Pear Theater in Mountain View. They have performed on the BATS Cave Match stage in San Francisco, the Countdown Improv Festival in Tampa, Florida, and were winners of the Suburban Thunder Improv Competition in San Ramon.
