About the Booster Club

The MIHS Softball Booster Club is an all-volunteer 501(c)(3) non-profit organization, separate from ASB. We bring families and community supporters together to support Mercer Island High School softball and help every player feel part of the team.

We supplement school resources, support coaches in developing players’ skills, and create opportunities for teammates and families to connect. Our goal is a positive, memorable softball experience on and off the field.

How Your Support Helps

Family donations, fundraising events, and business sponsorships help cover needs beyond the school’s ASB budget, including:

  • Team gear, equipment replacement, and upgrades.

  • Skills training, coaching support, and scholarships.

  • GameChanger subscriptions and video equipment to help families follow games.

  • Team bonding, dinners, Senior Night, banners, yard signs, and end-of-season awards.

  • Website costs, insurance, and other essential booster club expenses.

Support the Islanders

Our suggested family donation is $250 each season. Contributions of any amount are welcome and appreciated. Please choose a level of support that works for your family.
