Grand Valley Brazilian Jiu-Jitsu


With centuries of history and deep roots in personal growth, martial arts is more than a sport – it’s an art form. For this reason, we prioritize the quality of our school culture just as much as the quality of our training. From the moment a student walks through our doors, we do everything we can to make them feel at home. We consistently foster an environment that is safe, welcoming and uplifting.

Jiu-jitsu has a way opening your perception in how you think about yourself and your capabilities and also how you relate to and respond to others. BJJ is a discipline, one with respect. When you enter the world of jiu-jitsu there is no going back. You will outgrow your old self and discover your true potential and you will always have a family on the mats weather its in your own gym or across the world on some foreign mats. Jiu-jitsu is truly that kind of community. You learn to honor and respect your opponents and you learn to honor and respect your self.” ~ Nadia Sweeten
