Dr. Bob Laronga has been a student of martial arts for most of his life. At the age of six, he was placed in an accelerated school program, completing grades 1 and 2 in one year. He and his family relocated after that school year, and being one year younger than his classmates, he suddenly found himself to be the second smallest child in a third grade class of more than 30 children. Being a year younger than his classmates, he was one of the smallest children in his class throughout the growth years. At the age of twelve, he read a book on combat judo, and was intrigued with the concept of defeating a bigger and stronger opponent by using the opponent's force against him. At age 13, he enrolled in a Judo class that was held every Saturday morning. At that time, the oriental martial arts were just starting to gain popularity in the United States, and there were not very many schools around.

In fact, the Judo school offered Tae-Kwon-Do classes, but students had to be at least 15 years old to take the class. As soon as Bob turned fifteen, he started training in Tae-Kwon-Do. After high school, Bob stopped training to pursue his college education. Over the next several years, he would find periods of time in which he could resume training. During this period, he studied Tae-Kwon-Do under Master Yeon Hee Park, who was All-Korea-Japan national champion for six years. Again life demanded a suspension of training, as Bob pursued his Chiropractic education. After setting up his practice, Bob again resumed training, this time studying Shotokan Karate. He enjoyed the training, but always felt as if something was missing.

In all the years of on-and-off training, he never learned any techniques to use against a knife or a gun attack. Finally, in 1988, he began training in Hakko-Ryu Jiu Jitsu, under Sensei Al Cornacchio. He found the missing pieces in his martial arts education, and trained with Sensei Cornacchio until 1994, finally earning the black belt that he felt he could be proud of. He moved to Florida in 1994, and has since been teaching on a part-time basis. In 2004, with the full endorsement of his instructor, Dr. Laronga founded BCDK Aikijitsu, a blend of the best principles and techniques from all of his training. BCDK stands for Basics, Control, Discipline, and Ki, which are the essential elements of the style, and also represent the four levels of expertise.
