Meet the comedian
Meet Sib
Comedian. Writer. Professional bachelor.
Sib (Mark Sibbitt) is a Phoenix-based stand-up comedian, writer, and experienced entertainment host with more than a decade of performing under his belt.
Winner of the Funny Bone’s Clash of the Comics, Sib draws inspiration from his unconventional upbringing with his grandparents and the everyday adventures (and occasional disasters) of bachelor life without kids.
Having shared the stage with comedians including Josh Johnson, Rocky LaPorte, and Aries Spears, Sib combines personal storytelling, relatable observations, and his own offbeat perspective on life.
Whether performing stand-up or hosting an entertainment event, Sib takes audiences on a hilarious ride down the road less traveled.
