Word of mouth is always the best way to grow! Run a successful program that is dedicated to the kids learning life lessons through sports and your players and parents will talk you up to everyone they know! I strongly suggest the Positive Coaching Alliance for help in establishing a kid first organization.

You could always put flyers ou and put them around your town and if you asked permission, you could probably get elementary school teachers to hand them out, that happened to me a couple times for the YMCA, they handed us flyers for sports

If you're question is regarding ice hockey then I'd suggest you visit some roller hockey organizations.Many kids convert over to ice after they get a taste of the game.
Have a great day!

you could put up flyer and u can hove free little camp for the kid and u could have discount for the player.
