Instructors

Rubens Charles Maciel, aka "Cobrinha", is widely regarded as the greatest featherweight of all time and one of the best pound-for-pound Jiu-Jitsu competitors in the world.

In 2017 he won ADCC, Worlds, Pans, Europeans and Brazilian Nationals in the same year. No other black belt has done that.

Cobrinha earned his black belt under Fernando "Terere" Augusto in 2005 and is a member of Alliance Jiu-Jitsu. He has won nearly every World Championship he has entered (13 in total) and is known for his attacking style and a guard voted Best Guard of the Decade by fellow World Champions in Gracie Magazine.

Alliance Jiu Jitsu Puerto Rico carries his lineage and teaching system directly through Professor Will.

Professor William "Will" Candelario is a lifelong martial artist. He trained in several Japanese martial arts and represented Puerto Rico in karate as a member of the Puerto Rico Olympic team, competing at World Championships and international events around the globe and earning gold, silver and bronze medals.

After moving to Los Angeles, he met Rubens Charles Maciel "Cobrinha", a multiple-time World Champion and a legend of the sport. Will went on to compete under Cobrinha with great success, became an instructor under him, and built a school under his guidance in Los Angeles, California.

He then returned home to Puerto Rico to give back to his country and its people by bringing the Cobrinha System to Aguadilla. Today he passes that knowledge on to kids and adults across the island.

His mission is to change lives through Jiu-Jitsu and to build a community rooted in respect, love, compassion, greatness, resilience and discipline, empowering every student to follow their dreams.
