Rotarian Samuel Jefferson Frazier III gave a very impressive presentation on the Korean martial art, Tang Soo Do. He is the Grand Master of the World MATA Tang Soo Do Federation, the testing and ranking federation for all schools. Sam is also an accomplished pilot and yachtsman, and somehow finds time for his profession as a trial attorney with practices in both Northern and Southern California. Gold Country Rotary President Lynne Tinel is one of Sam's martial arts students.
