Arnold Sandubrae began his Isshinryu Karate training in 1973, under the instruction of Sensei's Robert L. White, and Sam Santilli, students of Master Willie Adams. Several years later, he transferred to train directly under Master Willie Adams because Master Adams Dojo was located only blocks from Sensei Sandubrae's office. From 1973 until 1986 he amassed over 200 trophies in all categories, Kata, Kumite, Weapons, and Breaking.
Sensei Sandubrae has had his own Karate School since 1978. That is when he retired from the business world, and moved to his home in Palm Springs, California. At that time, with the approval of Master Willie Adams, Sensei Sandubrae went under the leadership of Master Harold Long, Ju Dan. Sensei Sandubrae remained his student until Master Long's death in 1998. In June of 2002, Sensei Sandubrae went under the direction of an old time friend and Master instructor, Joel Chandler Ku Dan.

He has appeared on many National Television shows and Radio programs furthering the art of Isshinryu Karate. For the past 18 years to date, Sensei Sandubrae has been a Board Member of the prestigious Isshinryu Hall of Fame, and is an active Board Member of the Tatsuo-Kan Society. For many years he was a Board Member of the International Isshinryu Karate Association (IIKA).
Sensei Sandubrae has traveled, and continues to travel, to many places throughout the world, furthering the art of Isshinryu Karate by both attending and putting on training seminars in other countries.
