Having thousands of dives logged, Steve’s happy place is teaching and sharing his love for the water with others. After spending the past two years in Puerto Rico guiding and teaching full time, his wife and himself moved to Kansas City to be closer to the family and grandchildren.

He takes the responsibility of instruction very seriously and wants to make sure that all students have fun learning in a safe and comfortable environment.
