Whether you want to improve your fitness, learn self-defense, or develop new skills, Node Grappling provides quality training in a structured, safe and supportive environment.
Jiu-jitsu is a constantly evolving, practical approach to self-defense. A strategic battle, human chess, that sharpens the mind while strengthening the body. A fight, a sport, an art form, uniquely shaped by each practitioner.
At Node, we've built a community that unites people from every background, bound by a shared pursuit: to keep overcoming, to keep growing, and to center health, positivity, and respect in all areas of life.
As an official affiliate of the Mavericks Jiu-Jitsu community (established by Jon Thomas and Espen Mathiesen), our members learn from a world-class program.
When you train with us, you're not just joining a gym; you're becoming part of a global community dedicated to excellence.
Goal-oriented Training
We have different types of training programs for adults, juveniles and kids, to help you achieve your goals, regardless of your fitness level or preferred grappling style.
We offer classes in Brazilian Jiu-Jitsu,
submission grappling (no-gi), and judo.
We train, learn, and grow together through martial arts. Whether you’re here to compete, get fit, or roll with friends, our doors are open.
Our Culture
✔️ Safety first - we are a martial art gym, but we believe that safe training is most important.
✔️ Flat hierarchy - We have no masters or professors. Higher belts are a resource for learning, not a symbol of authority. Ask anyone for advice, and be open to rolling with everyone, regardless of rank.
✔️ Speak up - feedback and constructive criticism is valued; speak up to help us improve.
✔️ Tame your ego - The mat is a place for learning; you tap and get tapped. Be humble and thank your training partner.
✔️ Personal cleanliness - Jiu Jitsu is a close quarter combat sport. Come to class clean with clean gear and trimmed fingernails.
✔️ Wear what you want - we believe in freedom of expression, but your attire must be safe for grappling. Spats or shorts and rashguards works the best. In Gi classes we ask you to wear a Jiu-Jitsu kimono.
✔️ Have fun - most importantly, have fun rolling!

Our instructors
Rob
Rob, originally from Canada with Filipino roots, has lived in Estonia since 2011. Outside the gym, he works as a music engineer and producer, collaborating with global icons like Stevie Wonder and Bruno Mars, as well as Estonian stars. A father of three. Rob loves pizza, favors the color brown, and would be a T-Rex wearing underwear on his head if he could. Rob teaches kids’ jiu jitsu and lunchtime no-gi classes. Brown Belt in BJJ.
Efo
The guy who never smiles. Migrated to Estonia back in 2021 as a refugee from the happiest place on Earth: Finland. Efo has a unique background in military and security. As a Finnish Army veteran he has a unique approach to the sport and is more than eager to help out fellow veterans and law enforcement officers to learn unarmed combat skills. Responsible coach for Monday morning and Wednesday evening classes. Black Belt in BJJ.
Sophia
The mysterious one. Sophia is from the USA but has been living in the Baltics long enough to have lost all skin tone. No one is sure what she does off the mats, but at Node Grappling, she's sharing the secrets she's learned living and training in six different countries across four continents since 2013, when her Jiu Jitsu journey began. Sophia occasionally leads mobility/active-stretching with Jiu Jitsu recovery in mind. Brown Belt in BJJ.
Tommi
Tommi traded football sliding tackles for berimbolos and never looked back. Now a BJJ brown belt, coach, and co-founder of Node Grappling, he brings experience from training and competing worldwide—including at Unity Jiu Jitsu in New York—back to Tallinn, which he has called home for over a decade. You’ll find him running the evening gi classes, where inverting isn’t required… but it’s highly recommended.
Sergei
3× Estonian Judo Champion. EJU Tournaments medalist. World Judo Champion 2023. World Sambo Bronze medalist 2019 (Masters). Barber rarely receives pay from Sergei.
