5 Skills Every Child Should Know
The Greene County Guide to Bully-Proofing
Worried about bullying? We created a free, 5-step guide for parents to practice safety at home—no experience required.
- The Safety Roll: How to fall without fear.
- The Shield: Managing distance without aggression.
- The Verbal Loop: What to say to stop a bully.
When emotions spike, we use a calm “quiet power” reset called a Samurai Break so kids can cool down without feeling punished.

Choose your Style, Train in BJJ
Kids love games and character select screens. We use this artwork to show how Brazilian Jiu-Jitsu fits into the wider world of grappling styles – then we bring it to life on the mats.
- Built around real kids from Tannersville, NY
- Shows how BJJ connects to wrestling, judo, and more
- Used in class to explain positions and respect for other arts
BJJ Anatomy: Skeleton Basics
Kids don’t just roll around – they learn how their bodies work. We use this poster in class so students can point to their hips, ribs, spine, and shoulders and talk about what they feel.
- Teaches real names for major bones and joints.
- Makes safety talks easier: “my elbow feels tight,” not “my arm hurts.”
- Kid-friendly, game-style artwork they recognize and remember.
Parents are welcome to snap a photo in the studio and review it at home.

"I have been learning from Sandy for many years now, and it has been an incredible journey. Sandy's teaching style is not only effective but also enjoyable. His passion for developing better BJJ is contagious, creating an environment that's both motivating and supportive. His lessons are well-structured, blending proven BJJ techniques with modern training methods. Sandy's expertise is evident, ensuring that every session is not just a workout but a learning experience. I've seen significant improvement in my skills and confidence. The camaraderie on the mats adds to the positive atmosphere. I can honestly say he creates a community of growth and empowerment."
“Anyone who has ever taken a BJJ class can attest to how much you sweat in a session. The constant movement and maneuvering presents challenges to maintain optimal mind/body awareness and breath control so you do not die. Well, not really die, but the intense practice referred to as ‘porrada’ by Sensei Sandy, really keeps you in the present and focused. Intentional.”
“Met Sandy after his move upstate, his creative and technical style quickly made him one of my favorite training partners. As an instructor he takes the time to break down techniques simply and takes the time to help you reach your goals. With Sandy you’re in great hands! ”
