What we're about
Formerly known as the Old Girls’ League, the Association exists to keep our Dio community connected. With almost 17,000 members worldwide, it is a vibrant network of friendship, fellowship, and lifelong connection to Dio.
  • Events & connection

    We bring alumnae together through reunions, annual events such as Mothers’ Breakfast and Founders’ Day, and a range of other special gatherings throughout the year. It’s a chance to reconnect with old friends and create new ones.

  • Service & impact

    Our community leads with purpose. From initiatives like the Uniform Recycling Project to the new ‘Lunch and Learn series, we’re committed to making a positive difference together.

  • Legacy & engagement

    Alumnae are woven into every part of the Dio story, from the Board of Governors and the Heritage Foundation to staff, parents and volunteers. Wherever you look, Dio alumnae are giving back and shaping the future.

  • Growth & connection

    We believe connection fuels growth. Through speaker series, career development opportunities, and alumnae spotlights, we champion lifelong learning – honouring it through our Alumnae Merita and Ut Serviamus Awards.

Events & reunions

Each year we welcome alumnae back to the School for their 10, 20, 30, 40 and 50 year out reunions which are hosted on Founders’ Day (the first Saturday in November). In addition to this we also host a one-year out and five-year out reunion annually.
