Had personal improvised training from Gracie family in Prince George in 1990’s early 2000’s. Was promoted by Ryan Gracie who lived in that town at the time; Don’t show it off etc. My mother threw away the black belt when we moved out of province and because of other reasons about self defence aspects. Rickson Gracie may corroborate this story if you wish to ‘background’ check. Rickson was a very close friend and acquaintance of my Father at the time and earlier in the 80’s and 90’s. Renzo may also verify as they were also acquainted. True story but no certification. Thanks for you considering my profile. Respect.
