Tom Klassen: Executive Director

Tom Klassen

Mr. Tom Klassen grew up in Claremore, Oklahoma and started flying a spotting helicopter off of a Mexican tuna fishing boat in Central America at age 19.

He has had an exciting flying career having flown helicopter logging operations in Alaska, bush flying in Papua New Guinea, TV reporting in Boston, aerial firefighting missions in Alaska and the West Coast, tours in Hawaii, and a Russian fighter jet in air shows for seven years. However, in his over 10,000 hours of flight time, he feels that the twenty years spent transporting patients in helicopters has been the most rewarding.
