TESTIMONIES
"Training at Osmosis has been an incredible experience. The instruction is top notch-clear, detailed and always delivered with patience and encouragement. Ryan is a fantastic coach, not just in skill but but also in creating a welcoming and respectful environment. As a woman, I really appreciate how mindful everyone is about size and strength differences. The culture at Osmosis can only be described as as uplifting, respectful, and seriously addictive. It’s the kind of place where everyone supports each other, there’s no ego, and you’re always learning—not just techniques, but how to trust your training partners, bounce back after tough rolls, and have a good laugh even when you’re getting totally outmatched. I always leave class feeling more confident, challenged, and part of a real community!!"

"I've been training with Ryan for sometime now, when I learned he was starting Osmosis I was really excited to train under him. He is very knowledgeable and explains things very well. He has passed on these good traits to the other instructors too. The crew that go are great and friendly and the more experienced members are always willing to help with advice and showing how things should be done. Highly recommended."

He breaks down techniques clearly, encourages questions, and fosters an inclusive, ego-free environment where everyone feels welcome. Whether you're new to Brazilian Jiu-Jitsu or looking to sharpen your skills, this is the place to be. The community is friendly and supportive, and the vibe on the mats is always positive and respectful. Highly recommend Osmosis BJJ for anyone in Auckland looking for top-tier training and a great team culture"
