Meet the Team


Sijo Ross Whitby

Sijo Ross

Sijo (Head of School) Ross Whitby started training in Kung Fu and weights at the age of 12 followed by running an after school weight training club aged 14 and then became an instructor at age 16.

Jiu Jitsu and Kick Boxing followed soon after and then Nin Jutsu (Ninpo) and TaeKwondo at the age of 21, whilst travelling the world. Upon returning home, he added Chinese Martial Arts to his skill set whilst looking after the doors at various Reading venues (Purple Turtle, Mangos and Pavlov’s Dog, etc.), giving him great experience in dealing with verbal aggression and physical attacks from one or multiple opponents, both unarmed and armed. These pressurised environments helped him to refine the TMAS techniques and syllabus.

Ross is also a Personal Trainer (1-on-1 or small groups) and regularly works with Reading and Wokingham Councils, delivering martial art programmes in schools and self defence training into the wider society.
