Referee Clinic Jan 28th, 2014 7:30 at MVJ Dojo. Sensei Calvin Terada IJF “A” Referee put on a great Referee Clinic last night at the MVJ club. We had about 15 coaches, referees and competitors attend the 1.5 hour clinic. Calvin was kind enough to also join us on the mat and workout with our combined kids and senior classes from 6:15 to 7:30. The clubs that were represented at the clinic were, Anchorage Dojo, Mountain View Judo club, Mat-Su Judo Club, and also Artic Knights Judo Club was in the house as Christopher (Matt) Shelborne was in town and came by. It is always nice to have Judoka on our MVJ mats that are from out of town.
