He was one of only two students to enroll in a traditional instructors course at that time. The instructors course consisted of 5 days a week, 3 to 4 hours per day of intense training directed by Doju Nim. When the course was completed in 1989, he was rewarded with his 2nd degree black belt. Of all Doju Nim’s senior students, Grand Master Croaro is the only one who has never studied under any other martial arts master, and he now has the honor of being the longest consistent Sin Moo Hapkido practitioner.

Grand Master Croaro recognized his passion for Sin Moo Hapkido at the beginning of his training and has never studied any other form of martial arts. Years later, Master Yung Freda and an assistant Korean Buddhist Monk friend also recognized Frank’s passion and honored him with a Korean martial arts name for his strong belief in the mind, body and spirit philosophy.

In April 2014, Doju Nim awarded Frank Croaro with the title of Grand Master for his dedication and many years of support to Sin Moo Hapkido. Doju Nim also honored and rewarded him with his own Kwan (martial art, “Sin Moo / Shin Yong Do”) and title.
