Nathalie Prévost has been involved with martial arts since 1987 and is an advanced instructor in Pekiti-Tirsia System of Kali.  Nathalie runs a private group, primarily made up of advanced students and instructors.  Her main focus is developing a curriculum that emphasizes attribute development against larger opponents and sound teaching methodologies.  This exploratory training is regularly tested in the context of sword play and stick sparring.

Her style of teaching is strongly influenced by her studies in cognitive science, in which she holds a PhD.   She also follows the research of Joan N. Vickers whose focus is on effective training and sports coaching from a cognitive science perspective.
