His first outside and official instructor was Tae-Kwon-Do Master Tan in Isabella Puerto Rico he trained there for about 8 months and quickly decided that this style was not for him; he then moved on to Kung-fu (Choy Lay-Fut) with Sifu Jose Ramirez where he practiced for 13 months and still not finding what his brother was bragging about he moved on to Boxing where he only trained 7 months. Finally, in a tournament held in Aguadilla, P.R. he met Sensei Wilfredo Herrera, he had no idea how this man was about to change his life.

Sensei Wilfredo Herrera was practicing under Master Eddie Cardona in P.R. who was also a member of Master Vincent Cruz's organization (ISKA). Sensei Luis began his training in Shotokan Karate-Do with Sensei Wilfredo Herrera, he was immediately impressed by the dedication, discipline, control, and other incredible qualities sensei Wilfredo inspired. Sensei Luis loved Karate with a passion. He would spend countless hours before and after his scheduled classes training, he would also train in the park at night. Sensei Herrera taught him that the sky was the limit. He never trained anywhere else while he was in Puerto Rico and in return for his loyalty; Sensei Wilfredo Herrera gave him his best.

Sensei Luis earned his Brown Belt under Wilfredo Herrera; he was tested for this belt under the Funakoshi Shotokan Karate Association in a visit by Master Kenneth Funakoshi to Puerto Rico. Shortly after receiving his brown belt he decided to join the Army reserve where he was sent to Saint Louis Missouri for basic training and other additional training. He was then sent to Aguadilla Puerto Rico to serve his time. He participated in law enforcement operatives in San Juan P.R. where many reservists risked their lives to stop crime in drug known neighborhoods. At the age of twenty-three sensei Luis went to New York in search of a better life. Once he established himself with a regular job he found a Shotokan Karate School in Queens and practiced with Sensei Jose Jordan a Member of the U.S.A. Karate team where the equivalent of his Brown Belt rank was honored, Sensei Luis describes training with Master Jordan as one of the best experiences of his Karate life.

Having to move from Brooklyn to the Bronx he was unable to travel to continue his training with Sensei Jordan, after a couple of months he met Sensei Moises Dela Cruz a student of Thomas La Puppet where he received his Black belt in a test conducted by a panel of about 9 Black belts among them Sensei Moises DeLa Cruz, Shihan Cedric Barksdale, Sensei Ronald Cook, Shihan Victor Mosquera and other Black Belts from different schools an organizations.

Finally Sensei Luis Ruiz moved back to Brooklyn but Sensei Jordan was no longer teaching, therefore he was referred to Master Victor Mosquera and was accepted as a student, Sensei Luis continues to train with Master Mosquera and has received his Shodan (first degree), Nidan (Second Degree) and Sandan (Third Degree) Black Belts.

Sensei Luis Ruiz currently holds a third degree Black Belt in Shotokan Karate-Do. He lives in Brooklyn N.Y. with his wife and two boys, and has a daughter that lives in Florida.

Sensei Luis still carries the Shotokan Karate values as it was taught to him in Puerto Rico. In addition Sensei Luis is the Founder and Owner of the Goshin Ryu Traditional Shotokan Karate-Do.
