Greg Irwin
Greg Irwin has skillfully captained Shamu (the boat) for many years watching hundreds of handlers navigate open water problems. He is the first and last person on the water setting up and closing down problems for the day. Greg has an expert read on dogs and is a valuable flanker. He also does not steer towards the source, but rather lets the handler make the call.
Greg also makes a mean margarita that may be the highlight of your seminar. You've been warned.
