Many thanks to @Keanu_RusClub for tweeting the links!
Many thanks to Ed Carvalho for graciously sharing his photo with Keanu Reeves on the Team Carvalho’s FB page! Given the information on their FB page they appear to have been involved in training the actors in some capacity. Crrently, they do not appear in the credits for John Wick on IMDbPro. You can view the photo here.
