Pure Brazilian Jiu Jitsu Catherine Perret Unprofessional, rude, obnoxious coach Chicago Illinois

I had my kid competing at a jiu jitsu tournament, and the head coach of Pure Brazilian Jiu Jitsu was there with very dirty hair, Catherine, and she wouldn't stop screaming the entire time. She was getting almost hysterical, screaming constantly, over drastically celebrating when a kid from a different team would lose a match- really making these children feel horrible. She was coaching from behind the score keeper which is not allowed, and she was walking around mat to mat doing this. The other teams and competitors were all making comments about how unprofessional she was acting. She was a bad example for all children there. She was acting like an animal, and should be ashamed of herself. I would never let my kids train with her after seeing how she behaves. Very disturbing behavior. Loudest person in the room, and kept insulting and antagonizing competitors from other schools. Not a good example for kids or aspiring martial artists.
