What our students say

Don't just take our word for it, take a look at what our students have to say...

"Martyn Harris is a bold and engaging martial arts teacher who attracts students from all over the country to visit his Cardiff-based training centres. I have known him since the turn of the century and am proud to call him my friend. When you want the real deal as far as martial arts in Wales is concerned you can do no better than train with Martyn Harris renshi."John Burke - Renshi and chairman of the BAMA Devon

Martyn Harris is one of the most inspirational and talented karate teachers who I know. Absolutely worth to come to see also from a little further!"Juha Tuominen ( Finland )

Martyn Harris is a very inspirational teacher, knowledgeable, kind and very important in my Martial Arts journey. I would highly recommend anyone who has the chance to train with him and his fantastic students to do so you won't be disappointed.Clare Potter ( Devon )

Martyn Harris Renshi is a big man with a big heart for Karate. He cares about his art and instructs the students with a such a passion you can't but help fall in love with it as well. Both myself and my husband have trained with Sensei Martyn in Wales and in Devon and we have learnt from him and sweated in the process, but most of all we have had fun doing it, its very hard not to with this big smiling Welsh man stood out the front enjoying every minute of teaching us. I can't wait to train with him again as he helps in more ways than one with my Karate journey.Natasha Barlow - Devon
