“It may be time to fire up your audience with something new and entirely different.
The opening and closing general sessions of a conference can make or break the experience. It may be time to fire up your audience with something new and entirely different – for instance Jon Wee and Owen Morse, The Passing Zone, performing entertaining, motivational routines."
“Jon and Owen are so easy to work with. Their energetic and hilarious show was the perfect fit to take our fundraiser to the next level.
Not only is their talent remarkable, but they were able to customize the material in a way that felt the show was original for our audience. They incorporated just enough about our funding needs and the local community with a perfect amount of audience interaction so that our supporters felt this show was truly FOR us! Biggest concern was how to top it in the future."
“It was our sincere pleasure to have you entertain attendees at the Kiwanis convention in San Antonio. Believe me when I say: HUGE HIT! Also believe me when I say: I'm taking all the credit...and loving it!”
