“My 2 boys have been training with Master Jeffrey for a number of years. My eldest son, Jeremy who is now in Polytechnic is still training with him in self-defense. Discipline and respect are core values of Master Jeffrey. The other aspect that I also like very much about his training and as a parent am concern with is his concern for the safety of the students during training sessions. I have also observed that my sons are more confident of themselves which is crucial and important as they grow and mature.”

– Ms Hogan

“It is very good exercise while learning self defense. The lessons are always filled with
energy. The trainers are very kind, and they will know if you are unwell.  Learning to defend
ourselves is very important. It is very fun training with the trainers as they have spirit in
everything.”

– Katerina Lim

“JF Self Defense is really good and I appreciate being able to learn it. This art is entertaining
and really fun. You learn how to defend yourself in a fight and I love it!”

– Nina Courbet

“Ryan has helped me develop much more confidence in myself. The training is hard, but it
is worth it. Thanks to it I have learned to push my limits further and further.”

– Alexandre Linot

“I have been learning at JF Self Defense for a few months now. I really enjoy
the great atmosphere and the training. I have learned a lot and lost 6 kilos, while gaining
muscle. I recommend this to anyone seeking a good and intense training.”

– Sebastian Priarollo

“Ryan has taught me many ways to defend myself from an assault. The training also helps me
to be more motivated to do physical exercises and it helps me to stay fit.”

– Meriadeg Le Neel

“The training has been very informative and interesting. It covers a wide
spectrum of defensive techniques. Both Jeffrey and Ryan are wonderful teachers that push
you and help you to reach your potential. I would definitely recommend this course to friends
and loved ones.”

– Nick Olinik

“I could not find a more efficient and useful training anywhere else,
both psychologically and physically.”

– Alexis Gautier

“I have been following Ryan’s course for a few months now. It has proven to be very useful. It is
very diverse yet everything we learn is useful. The organisation and the length of the class
is very good. Every move we learn is simple yet very effective and the physical training at the
beginning of the class is very good to develop your mental and physical strength.”

– Nicolas Selukov

Master Jeffrey is very attentive to details and a very experienced individual. With every
question raised, he tends to them with great patience and ensure our queries are answered.
Attendance to his training lessons, I have seen myself coming up as
fitter (both physically and mentally) individual. It also greatly enhances my knowledge on

different modes of attacks and ways of countering attacks that could possibly be available.
Overall, it is a very enriching experience under his watchful eye and guidance.”

– Ms Geok Hong

“The training was very interesting and useful. It is great to get this kind of knowledge and I will
definitely share it with my loved ones.“

– Henna Paivanne-Andersson

“The lessons are awesome! I wake up so motivated every Sunday morning to attend class. I
have always wanted to learn some kind of martial art to give myself a form of self-protection; I got more than I bargain for from Master Jeff. He is a real-life action hero; he is a mixed martial arts coach whom teaches the rope of real self defense using various techniques that is not available in any single martial art form. His emphasis on techniques rather than raw power has enhanced my self-confidence. Indirectly, my stamina and mental power has improved tremendously after 2months of training!”

– Koon Leng

“I got very useful tips for the hotel safety. I also enjoyed the practical session about the
different techniques of self-defense.” 

– Marika Arovuo

“Very useful course; raised many issues I would have not ordinarily considered; made me
more security conscious and I will be applying what I learned on future travels and other
occasions.” 

– Stina Malik

“Very practical and useful tips on things I had never before thought of. The hands-on
techniques were exciting to learn, and I definitely want to learn more!” 

– Virpi Tervonen

“Very interesting and informative; some new ideas and I appreciated the practical and
applied session particularly.” 

– Joanne Flinn

“I found the self-defense classes very informational as I will be moving to USA, Philadelphia
for my studies. Jeffrey is not only a very detailed Trainer, but he also ensures the safety of the
training sessions with precautions. I particularly like his use of humour in order to let us
understand certain concepts. The course was certainly useful”

– Yingjiao

“Master Jeffrey’s classes are the kind that you can take home with you because he does not teach a lot at once. He teaches us what we need to learn and he knows how to analyse our stances, posturing, distancing, striking, kicking, etc. By doing so, he knows very well what our weak points are and also our strengths and therefore he knows what to focus on. He has a catch phrase and it goes like this: “There’s no two ways about it”. Overall, he’s a very good teacher, one of the best I ever had.”

– Dennis Lim / Cavern NS men

“This workshop had very practical tips and useful simple techniques that every woman
should know.”

– Serene Mak

“Very useful information shared during the workshop. Really knowledgeable Trainer and
some of these skills may ultimately save someone’s life one day”
