"Thank you so much, I am proud to be your teacher and you are a credit to what I have taught you. That is why you are the highest ranking student in IFO, and as people know, I don't give out certs or compliments, unless they are deserved...and you deserved it." -Tommy Carruthers

"Excellent training for effective self-defense against one or multiple attackers. Instructor Thomas Marx can convey the decades-tested techniques of Original Jeet Kune Do superbly: effective punches, kicks, and finger strikes. An absolutely well-thought-out concept for both women and men of any body type, convincingly drawing on insights from biomechanics and sports science. Special focus: developing a meaningful posture, agile footwork, and automated movement sequences. Varied training repertoire, including repeated simulations of realistic combat situations: dim lighting, suddenly appearing attackers, defense from a seated position. No gimmicks that only professional fighters can use, no fruitless repetition of traditional forms inventory like in Wing Chun, which is useless in actual combat. In the Rödelheim training group, advanced students help beginners, the instructor corrects meticulously and motivatingly, creating a focused yet pleasant atmosphere. The group is diverse in age, gender, and background, making it easy to get started. Highly recommended."  -Jott Wurech

"I am glad to have found this school. The atmosphere is very pleasant and characterized by mutual respect. The instructor has a true talent for conveying knowledge and, above all, the pure and original Jeet Kune Do. Techniques are practiced here until they can be executed almost automatically, while gaining a deep understanding of the martial art’s background. The focus is on the essentials. This quote fits perfectly: 'I fear not the man who has practiced 10,000 different kicks once, but I fear the one who has practiced one kick 10,000 times.' For me, every training session so far has been enriching. I can therefore wholeheartedly recommend it."  -L. Koch

"For those coming from traditional martial arts, it’s initially a bit of a culture shock. No katas, joint locks, or high kicks. No strength exercises like push-ups or sit-ups either. Instead, the training is limited to a handful of techniques. This school does not train competitors; the focus is purely on self-defense. Great emphasis is placed on clean technique and its concrete application in all imaginable situations. Here, Jeet Kune Do rightly earns its classification as a martial ART. The instructor is fully dedicated, and the atmosphere in the group is friendly and respectful." -Ralf Hohmann

"I feel like I have truly arrived, and I owe that to our instructor Thomas! Great atmosphere, a familial sense of togetherness! I am thrilled! If you want to get to know the true Jeet Kune Do of Bruce Lee, I highly recommend that everyone form their own impression and join a trial training session!"
 -Cio Izci

"A very competent instructor who prepares with passion for real-life situations. If you are looking for a close-knit group that trains with dedication, this is the right place. I am happy to recommend it."
 -Alice Salomon

"Amazing school!! Pure and original Jeet Kune Do. Pure self-defense with maximum effectiveness. This school operates under the name of Tommy Carruthers, who was in turn trained by Bruce Lee’s students."  -Robert Schilke, Personal Trainer

"I have been training here for years, and it’s worth staying and participating. For anyone who wants to defend themselves on the street in emergencies. Regardless of being male or female. Simply highly recommended." -Fabian Frincu
