"Just short of entering the water on my first training dive with 4 other students, Bill was confronted by an irate beachmom whose daughter had accidently buried a large barbed fishhook into the inside-base of her ringfinger while swimming. Bill stopped the class, calmed the mother and daughter, removed the fishhook in seconds without the girl crying, gave the mother medical instructions, and calmly gathered his students for our first dive. We all knew we had the right instructor. Bill would keep us safe - by himself."
