Master Propst (Dan # 20636) began his Tang Soo Do training in Los Angeles California in 1971 under the guidance of Master Chuck Norris. He was promoted to the rank of 1st Dan in 1978 by Master Jae Chul Shin (United States Tang Soo Do Federation).

The year 1985 marked an historical time for Master Propst as this was the founding year for the Yuba Sutter Tang Soo Do Academy as well as the beginning of over 24 years as a student of Grandmaster Andy Ah Po. Sa Bom Nim Propst received his 4th Dan promotion from the late Kwan Jang Nim Hwang Kee in 1989.

Master Propst was recently awarded the rank of 7th Dan by Grandmaster Ah Po and continues to further his Tang Soo Do knowledge often accompanying Grandmaster Ah Po worldwide as he presents special clinics and symposiums.

Master Propst and all of the Dans of the Yuba Sutter Tang Soo Do Academy are members of the Tang Soo Do Martial Way Associaton.  As such, they are dedicated to teaching the original concepts and philosophies as defined by the late Kwan Jang Nim Hwang Kee.
