I have had the honor of knowing Richard (aka "Tricky") for the past 2 years. It takes a unique combination of personal characteristics to teach individuals in an environment as intimidating as an aquatic one. Let's be honest...humans were just not designed to exist underwater. Just look at how we get all wrinkly after just a few minutes in a tub!
Exploring this environment requires the right technology. But, the best equipment is useless without the proper training, both mental and physical. The parents of the participants of the Stay-Focused adaptive SCUBA diving program entrust Richard and the other carefully selected instructors with their children. And, I don't think these parents could have made a better choice.
