"My 10 yr old son has grown and developed not just in JJS skills here, but in character and specifically leadership. He brings his best self to GB because he is inspired to do so. He has learned how to handle sparring, understands how to challenge his opponent without hurting them, and welcomes every new kid to the GB family because he knows how to be a better person by example from the team here. Prof. Jaime & Prof. Daniel have incrementally given my kid challenges for him to stretch himself like leading group warmups for a few minutes or leading younger kids in games. He has come home so proud of his achievements. These little things have made a big difference. My son also goes to UFC for boxing so JJS is available to him at no additional cost, but we stay here for JJS. Totally worth it! Also, they have some ladies who coach so it’s nice to see!"
"I had been looking for an activity to put myself in last year and knew I wanted to go back to martial arts. When I contacted and met Professor Jaime and Professor Daniel, I felt so welcomed immediately. Everyone trains hard together, motivates each other, and laughs hard together. I really couldn't ask for a better group of people to spend my evenings with."
"Been training here for almost 6 months now and still one of the best decisions I have made. I had no idea what to expect when I scheduled my trial course with professor Daniel. However, after a short one-hour trial lesson, I was won over by professor Jaime and professor Daniel's professionalism and camaraderie. Their teaching spoke for itself. Over the short time period I have been here, I have not only have the opportunity to learn from the most caring, funny, and genuine instructors, but also met other amazing students and have grown to be teammates with them. Going to class doesn't feel like a dragging obligation, because this Gracie has fostered such an inclusive and welcoming environment that truly makes everyone feel at home."
"My daughter has received so much from this training. Discipline, integrity and strength. Not just physical but mental. She looks forward to attending each day, eager to get suited up ready to elevate each time. Thank you coach Jaime and Coach Dan."
