I am so surprised by the negative comments about Stephan Goyne's Rocha Jiu JItsu on Grand Avenue that I feel certain they must be confused with another place! Stephan Goyne has been teaching my daughter for 2 years now, and I find him to have a masterful combination of patience, clarity, motivation, and skill with the kids. Stephan does not tolerate acting up, but he does it in a way that is positive and decisive. My daughter feels empowered and energized from her experience here. I also really appreciate that Stephan has 2 other helper instructors in every class, so that the kids get a lot of 1:1 attention. My only negative is that occasionally the class size is too large.
