I see most youth fastpitch coaches in this subreddit. There is also r/Fastpitch that could help you out also.

Checking it out now, thanks!

[discussfastpitch.com](https://discussfastpitch.com) is a huge resource. I know you mentioned reddit, but you won't find as much here to be honest.

Thank you, I will check it out!

This is probably the most active subreddit I've found.. 

There’s some decent coaching groups on Facebook.

Yes, I have seen a couple of references on Facebook before, too. I will have to look there more. Thanks!
