About Sean

A little about Sean – As a long time scuba diver and an avid outdoorsman, Sean enjoys a lot of activities nearly all of which involve being outdoors. At the office, Sean deals with almost everything from training, RSTC, Insurance, and everything else that involves company relations with other agencies, manufactures and the industry as a whole. During most of his off days when not at the beach with his sons, you can find Sean enjoying kayak fishing, canoeing, cycling and walks through local parks introducing his kids to the outdoors and helping them identify the flora and fauna. “I have been fortunate enough to live and travel around the world and one day will be able to take my sons to some exotic destinations.”

3 Questions You Should Never Ask Your Instructor

There really is never a bad question but always think about the question before you ask it; put yourself in the instructor's fins.
