Global Underwater Explorers (GUE) Instruction at Extreme Exposure

doug-instructor.jpgDouglas Mudry is a GUE Fundamentals, Recreational, DPV, and Cave 1 Instructor. His years of experience interning under some of GUE's most admired instructors, as well as extensive knowledge of proper gear configurations, and his role of primary support diver for the WKPP all contribute to making him a very skilled instructor. His teaching schedule includes several standard five-day Fundamentals classes, as well as a few classes planned over the course of two weekends, allowing students time to digest material and practice skills prior to an evaluation. If you are interested in either course format, or would prefer to schedule your own course with your team, please contact for more information.
