Our instructors
Bill Dunn

Bill received his certification as a cave diver in 1974 through the NACD (National Association for Cave Diving). He is one of the first 100 cave divers certified by that organization, which at that time was the only organization in the U.S. that offered cave diving certification.

In 1980 he earned his scuba instructor certification through the YMCA scuba program and crossed over to NAUI in 1983. Also in 1983 he received his certification as a cave diving instructor through the NSS CDS(National Speleological Society Cave Diving Section) and later through the NACD. Currently, Bill teaches cave and technical diving courses through IANTD and recreational scuba training through NAUI.

In 2004, Bill celebrated his 30th year of active cave diving. During those three decades, he has conducted literally hundreds and hundreds of safe cave dives in such diverse places as springs, sinks, sumps, Mexican cenotes, and Bahamian blue holes. He has participated in a number of exploration, survey and mapping projects of springs and sumps in Fla., Ga., Ala., and Tenn. He is an active participant in such cave diving specialties as stage, sidemount, extended range/decompression, and dpv diving.
