Master Instructor

Kyoshi Maldonado began his karate training in 1962 under the tutelage of his older brother Nickolas Maldonado. He later went on to formally practice and teach the art of Ji Do Kwan, Korean Karate, from 1966 to 1969 in New York City after which he enlisted in the US Air Force. While in the military, he taught karate to hundreds of U.S. service men and women in Europe and Asia.

In 1978, he was assigned to Kadena Air Base on the island of Okinawa. During his first six months there, Kyoshi established a Ji Do Kwan Karate club that eventually grew to 120 students before the end of its first year.

Kyoshi Maldonado, along with his friend, Hanshi Marquez (pictured above), were given a special invitation to meet the famed Goju-ryu Karate Master, Masanobu Shinjo, 9th Dan - the founder of Shobukan Goju-ryu.

Prior to the departures of the Kyoshi and Hanshi from Okinawa, Master Shinjo promoted Hanshi Marquez to 6th Dan black belt and Kyoshi Maldonado to 5th Dan black belt; both with entitlements of Sensei and official license to teach Goju-ryu Karate worldwide.

Shinjo has had karate schools in England, Germany, Okinawa and the US, training and promoting dozens of Goju-ryu black belts.

Master Shinjo Masanobu passed away in 1992. It was then that Hanshi Marquez began the foundations of his own system, Tanzenbukan Goju-ryu Karate and in 1997, Kyoshi Maldonado officially accepted an invitation by his colleague and friend to join the organization.

Kyoshi Maldonado retired from the U.S. Air Force in 1993 after 24 years of service.  He is on the Drug Court teams for Martin County under Judge S. Levine, Okeechobee County under Judge G. Bryant and the Mental Health Court in St. Lucie County under Judge C. Cox.

Kyoshi Maldonado has been teaching Goju-ryu Karate at Kaizen Karate and Fitness Dojo since 2005. One of his closest and dearest friends, the late Sensei Tom Bogolowski, the establisher and former owner of Kaizen Karate, was his personal student.

During Kyoshi's 47-year career in the martial Arts, he has won numerous Karate tournament titles and accolades and he was bestowed the title of Sei-Shihan and Sensei, 5th dan black belt, during a special ceremony on the Island of Margarita in Venezuela by his friend and founder of the Tanzenbukan Goju-ryu Karate-Do, Hanshi Anthony C.
