It looks like DiscNW is still accepting registrations for a free Sept 16 coaching clinic, and may offer another in October of this year (2017). This may be of interest for beginner coaches (<~2 years experience) working with elementary or middle school players.

I attended one of these last February and it was very helpful. It’s facilitated by the amazing trio of Shannon O’Malley, Heather Ann Brauer, and Alyssa Weatherford.
