Greg Fitzsimmons is a veteran stand-up comedian and writer who transitioned his long-running FitzDog Radio program into a video-first production through Gotham Production Studios. A four-time Daytime Emmy Award winner for his work on The Ellen DeGeneres Show, Fitzsimmons utilizes his professional background in the New York and Boston comedy scenes to deliver sharp-tongued interviews and irreverent social commentary. He frequently collaborates with industry mainstays, recently hosting guests like Jeff Garlin and Ali Siddiq to discuss the mechanics of performance and personal history. Aside from his central show, he co-hosts the podcasts Childish and Sunday Papers, exploring family dynamics and news through a comedic lens. His recent solo episode marking a major birthday highlights his move toward candid storytelling regarding aging and mental health. This perspective is further documented in his book, Dear Mrs. Fitzsimmons, which serves as a foundation for his comedic identity centered on his Irish-Catholic upbringing in Tarrytown.
