John Cassidy's bizarre antics have earned him widespread acclaim as one of the most original comedians performing today. Starting his career as a magician and balloon sculptor for children’s birthday parties, John began noticing that the parents were also finding his act to be especially hilarious and ingenious. Convention work and college dates soon followed for this neurotically charming performer. The world of magic has taken a special shine to John and he is now among the most requested acts at various conventions and seminars throughout the world.

The Amazing Johnathan, in particular, has hired him as his opening act on numerous occasions over each of thepast four years. In addition, Kevin James, Mac King and Teller (of Penn&Teller) have all made their own special requests for John Cassidy's blend of creative mayhem.

Further notoriety for John occurred when the Guinness Book of World Records documented him as the world’s fastest balloon sculptor. Within the course of a mere sixty minutes, John both inflated and twisted 654 balloons.

John has made numerous television appearances on such shows as “Martha Stewart Living”, “The Today Show”, The CBS Early Show and “Live With Regis and Kelly”. In addition, John has also been honored to have performed at the White House for the past two years.

He currently resides in the rural outskirts of Philadelphia with his wife Jennifer, a Bernese Mountain dog (Bella), two bunnies (Samantha and Tabitha), and two doves (both named Steve).
