Pedro Iahnke de Oliveira Crixel

I was born in , Porto Alegre-RS, Brazil. Black belt in Jiu Jitsu under Cicero Costha.

I’ve been training and competing for the past 12 years. I have been part of the most successful teams in the sport including Atos (San Diego), Unity (New York), and  Cicero Costha (São Paulo).  I have been developing my instructorship since 2016 with the goal of providing an elevated method of material delivery for students. Beginners seeking health and well-being or professional fighters can meet their goals under my Jiu-Jitsu (Gi or NoGi) programs. In 2018 I became one of the head coaches of Cicero Costha HQ, training world-champion athletes. Now I am ready to start my own venture in Clearwater Florida developing the skills of new students, athletes, and kids under our brand, Concept Jiu-Jitsu. You won’t find me on social media ignoring a class. I will be with each student, identifying mistakes and helping them make the proper adjustments for success.
