What to Expect
Your First Class
Never trained before? No problem. Here's exactly what happens when you walk through our doors.
Arrive Early
Come 15 minutes before class starts. Wear comfortable athletic clothes (t-shirt and shorts or sweatpants). We'll provide a loaner gi if needed.
Meet Your Instructor
We'll introduce you to the professor teaching class and give you a quick tour of the facility. Feel free to ask any questions!
Warm Up Together
Class starts with a group warm-up to prepare your body. Don't worry if you can't do everything—just move at your own pace.
Learn Techniques
The professor will demonstrate 2-3 techniques. You'll partner up with someone and practice together. Everyone starts as a beginner—no one will judge you.
Live Training (Optional)
More advanced students may do light sparring. As a beginner, you can watch or try it at a very relaxed pace with an experienced partner.
Cool Down & Questions
We finish with stretching and group discussion. This is a great time to ask questions about membership, schedule, or your next class.
Still Nervous? That's Totally Normal!
Every single person in our gym was a nervous beginner on their first day. Our instructors and students are here to help you succeed. You won't be thrown into anything you're not ready for.
Our Philosophy
Technique, Discipline, Community
"Brazilian Jiu Jitsu is more than just techniques—it's a journey of self-discovery. Every time you step on the mat, you're not just learning how to defend yourself, you're learning discipline, problem-solving, and mental toughness that translates to every area of your life."
— Professor Diego Herzog
Fundamentals First
We build a strong foundation through systematic technique progression. Every movement has a purpose, every position has a counter, and every student learns at their own pace.
Supportive Environment
Our academy is built on respect and camaraderie. Higher belts help beginners, and everyone grows together. Whether you're training for competition or personal growth, you'll find your place here.
Proven Curriculum
Led by Professor Diego Herzog (4th degree black belt), our curriculum has produced multiple competition champions and hundreds of confident practitioners. We focus on practical techniques that work for real self-defense and sport competition.
