I was introduced to martial arts in June 2008 when I did my first BJJ class. Later on I tried Japanese Jujitsu, Tai Chi and Muay Thai. I found these arts fascinating in their own way, but I was drawn to BJJ’s unique style.

Along this journey I have witnessed how martial arts positively impact people’s life by improving physical and mental health. My personal and professional interest is to share knowledge and experiences that have the potential to enhance individuals’ quality of life. As a result of this passion I decided to follow a dream with Jeremy and open an academy where everyone could have access to martial arts and enjoy the benefits that come with it. So here we are, running Grand Martial Arts, a place that have changed my life completely and where I have met amazing human beings!
