Master Marsh's interest in martial arts started as a child of 4 years old. He began his studies in 1964 with Judo while living in Japan with his parents. After his family returned to the USA, he continued his Judo training until their move to North Carolina in 1973. His studies ended as Judo training was not available.

In 1990 he began studying and training in Tang Soo Do. By 1992 he had been promoted to 1st Dan (Black Belt). As a student of Grand Master Jae Joon Kim, he was promoted to Master (4th Dan) in September 2000 and most recently promoted to 6th Dan in November of 2007. He has enjoyed sharing the art of Tang Soo Do as a perceptive, encouraging and generous instructor for 14 years.

Due to his wishes, Cary Tang Soo Do maintains its responsibility to provide a high standard of martial art instruction in a non commercial and safe environment.

Master Marsh is also considered somewhat of a renaissance man by his students. He is an successful bee keeper, gardener and skilled handyman - and always willing to share his interests with his students.
