GameChanger, the popular app for amateur sports stats, scorekeeping and live game updates, unveiled a campaign Thursday to recognize the amount of time and energy youth and high school coaches put into their teams.

With the school year wrapping up, GameChanger has put together a video as the start of a series that will thank coaches for their hard work and dedication, on behalf of their teams and players.

GameChanger has a network of more than 100,000 coaches, but the series spotlights four coaches selected through recommendations from GameChanger staff and users of the product.

• Dave Boff – Basketball coach at Roselle Catholic High School (Roselle, N.J.)
• Cathy Rudy – Softball coach at Martin High School (Arlington, Texas)
• Steve Henderson – Football coach at Aragon High School (San Mateo, Calif.)
• Roc Murray – Baseball coach at Rockland High School (Rockland, Calif.)

As part of the campaign, GameChanger is asking players, coaches, school officials and parents to use  #ThankYouCoach to share their stories.
