Rusty Davis

Rusty has been diving with Louisville Dive Center since his wife Shelly enrolled them in SCUBA classes as a Christmas gift in 1994. He became a NAUI instructor in March of 2003 and added instructor ratings with SSI, SDI, ASHI and DAN over the next few years. In 2005 Rusty became a NAUI Instructor Trainer. Also in 2005, he earned his Captain's License through the United States Coast Guard. Rusty's experience in SCUBA instruction varies from open water & try SCUBA classes up through leadership & public safety. He has had opportunities to dive environments from cold-water inland quarries to exotic tropical dive destinations but one experience will always standout. In 2016 Rusty had the privilege to teach SCUBA to a crew of Boy Scouts which included his own Eagle Scout son Connor. Once the crew was certified divers, they went on a week long live aboard SCUBA sailboat trip in the Florida Keys through the Boy Scouts of America's Sea-base High Adventure program. Rusty got to serve as an adult leader on this trip and see the group of young men he had known since they were little boys in Cub Scouts enjoy the undersea world that SCUBA had opened up for them.
