Please tell us the story of how Nerds of Jiu-Jitsu, Switzerland came into existence
Long story short: I’m a nerd. I’ve always needed deeper explanations: how things work, the systems behind them, the strategies, and what actually works at the highest level, backed by data and real results.
From blue belt to brown, I was in charge of the kids’ class, and that responsibility sparked a strong desire to teach only quality, effective techniques. To do that, I turned to the best resources I could find: instructionals from Danaher, Musumeci, AOJ, and others. Over time, I realized that to train and teach the way I truly believed in, I needed full freedom. That meant stepping away from the limitations and frustrations I experienced in other gyms.
So, I left. I opened my own gym. And I built it the way I always wanted: thoughtful, structured, and focused on real growth – for everyone, especially the one discovering the art of Jiu-Jitsu.
Tell us about the people that train in the gym – who are they?
They’re simply amazing. I feel incredibly lucky to work with every person who steps on the mat. They’re kind, respectful, and genuinely look out for one another. They train with intention – technical, curious, and always striving to improve. Every day, they grow stronger and challenge me both physically and mentally.
I’m not a fan of calling it a “family,” since that word can feel a bit forced, but the truth is they’re exceptional people. They’re the reason this project keeps moving forward.
Why do they train in Nerds of Jiu-Jitsu, Switzerland?
Everyone comes with their own reasons. But I think, deep down, they love solving problems. They enjoy being face to face with themselves, learning to handle stress, navigate strong emotions, and stay calm under pressure. There’s something deeply satisfying about catching a partner with a move they’ve worked hard to add to their game.
Some come to feel better, to accept themselves, to overcome past trauma or build confidence. Others come to meet friends and simply share a great time on the mats. Many also train to let go of the pressure from daily life, work, and family responsibilities. It’s their space to breathe, reset, and reconnect with themselves.
What are some of the challenges of running a BJJ gym in general, and in your area specifically?
For me, the biggest challenge is ensuring real, tangible progress for every member. That means more than just running classes. It requires building a clear system. I had to codify the art, define what’s expected at each level, and map out the key concepts, systems, and solutions to a wide range of problems. That part takes time, careful thought, and constant refinement. But it’s also what makes the experience meaningful.
The rest is more straightforward. Cleaning the mats, for example, is easy. I have a giant robot named Francis, equipped with dedicated cleaning products. He doesn’t get nearly enough credit for keeping the place spotless and germ-free.
In my area, one of the biggest challenges is simply generating enough interest in BJJ to get people to try it, or to bring their kids. Prices are high, and rent is expensive. On top of that, we receive no support from the government. BJJ is still not officially recognized here, certainly not at the level of sports like Judo. It’s something to seriously consider if you’re thinking about opening a gym.
How do you see the future for BJJ in your area?
I can see interest growing, especially in bigger cities, which is a good sign for the sport overall. That momentum eventually reaches smaller cities like ours. As more people discover BJJ, curiosity spreads. It gives us a chance to show what we offer and to build something solid, even outside the main urban centers.
What’s the best thing about Nerds of Jiu-Jitsu, Switzerland?
The people, without a doubt. They’re some of the best human beings I know, regardless of rank, belt color, age, profession, or family situation. On the mats, we’re all equals. They help me grow just as much as I help them. That mutual respect and connection is what makes the gym truly special.
What would you recommend Globetrotters to see in your area apart from the inside of your gym?
There are plenty of great gyms to visit nearby, especially in Lausanne and Yverdon. But if you’re here, take the time to enjoy the region. Swim or paddle on Lake Neuchâtel or Lake Geneva, hike through the Jura or the Alps, and don’t miss out on a proper cheese fondue. And of course, eat way too much Swiss chocolate and drink a little too much local beer. It’s all part of the experience…
