Hey guys. I’m checking out a local BJJ club, Jiu-Jitsu Nation on Marcy, NY. The instructor, Len Sonia, claims to hold a black belt. I’ve done some searching on line, and I have found him listed as a competitor in a few competitions, but I still want to do some more digging.
I thought that there was an on-line registry that listed BJJ black belts and the teacher that certified them; am I right about that, and if I am, does anyone know where it’s hidden?
