The MBC Old Girls Association was established in 1917 and seeks to maintain valued friendships, foster networks, and provide relevant opportunities for our 7,500+ past students; keeping their connection with the College community alive.

In 2017 the Association launched an online portal allowing past students and staff of the College to come together and share news, photos, employment opportunities; find out about upcoming events and more. Information on membership to the Association is also available via the portal.

Past staff and students of the College are encouraged to register online for regular updates:
