Frank Schermerhorn entered the Moo Duk Kwan discipline in September 1972 at the age of eighteen,
at the University of Scranton under Mr. Joseph Margitich. He rose to distinction early and was passed 3 belt levels in his first test,
becoming a green belt in 3 months. By 1974, he was teaching Tang Soo Do at the University and was president of the school's Karate Club.
Later that year, his instructor sent him to Susquehanna County to open a branch of the Upper Valley Tang Soo Do School in Hallstead, PA.
