About Us

Would you rather your “family activity” be created by marketing departments and video game companies, or by parents and educators?

GPTrex was founded in 2009 when a group of parents and educators came together around two common goals:

  • Find new ways to provide affordable, fun, whole-family activities; and
  • Generate support for the community’s cultural, historical, and educational venues.

While GPTrex has grown to include a number of partners and contributors, we are still a company owned and operated by parents and educators focused on providing real-world adventures that are perfect for family fun time! Our core team consists of:
