Scott Shamblin began his training in Isshin-Ryu karate on November 16, 1973, under the instruction of J.C. Burris in Athens, Tennessee. His study continued with Angi Uezu, first in 1987, in Fredericksburg, Virginia, and again in 1993 as Mr. Shamblin traveled to and trained in Okinawa. He has also been a long-time student of the late Allen Wheeler of Powell, Tennessee. Mr. Shamblin has also studied Torite Jutsu, Sport Jujitsu and Tae Kwon Do.
He was the winner of the 1974 Isshin-Ryu Junior Championships held at the Knoxville Civic Coliseum. He was the first person at the Isshin-Ryu Hall of Fame Tournament to ever win first place in Weapons, Kata, and Kumite as well as Grand Champion in Kata, Weapons and Kumite.
Mr. Shamblin was the youngest black belt to win the Kata Grand Championship at the Battle of Nashville. He was the overall champion in weapons, Kata, and Kumite for the Tennessee Karate Circuit in 1990. At the 1999 AAU Nationals, he received the bronze medal for Kata, silver for weapons, and brought home the gold for fighting. He was undefeated in fighting that year at the state, regional, and national levels.
Outside the competitive arena, Mr. Shamblin has had the honor of participating in the Isshin-Ryu Karate demonstration during the Restoration Festival of Shuri Castle in Shuri, Okinawa.
