Portrait of Brad Waldron, BJJ Black Belt

"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."

Melissa DeGasperis training with Head Instructor, Sandy Jose Nunez aka ‘Spicy Sensei’ at Ascension BJJ in Kingston, New York during Free Intro Class

“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.”

Portrait of Chris Croteau, BJJ Purple Belt

“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! ”
