I knew him by Kym Tachibana which I think is his real name but who knows what he is going by now?!? He trained with my garage group off and on for about a year or so. However, once we combined with Power Team (now Marra Senki BJJ) he went his own way.
As far as him being an Assistant MMA instructor for Team Tabmoc in an official capacity...NOPE! Like I said, he did train with us and he did work (spar/roll) with one of our active fighters at the time. This was because of his lighter weight and he did have a blue belt skill level in grappling. But he never cornered any of our fighters or was more than a training partner for any of them.
Once we parted ways he did rent a small facility here in San Antonio (which I think his parents paid for). I think he called it "The Dojo" but not sure. It was only open for a few months and I was told he had a handful of students at most. I deployed to Iraq at the time and when I came back I was told by one of our team members that he moved away from San Antonio. I think he moved to Austin for awhile and then to Houston.
As far as the rest of his resume...I couldn't tell you what is factual and what is not.
The only official MMA Coaches for Team Tabmoc at the time were the following:
Myself - currently coach MMA at Marra Senki BJJ (www.marrajj.com
Rudy Hernandez - Current owner of the Spartan Pit (www.spartanpit.com
Wally Herrera - Not currently training but he ran training in my absence while I was deployed and helped corner fighters.
Hope this helps...
