The Annual Dinner is the Club’s flagship event, at which the new President is inaugurated. It is a black-tie occasion, held in late September/early October at a prestigious Central London venue selected by the outgoing President.

The Club encourages OMs to take reunion tables – e.g. Houses, Sports, Oakers etc.

The Club entertains guests from the Foundation, including the Chair of the Court of Governors, the CEO, School Heads and Mill Hill School Monitors. Spouses/partners are always welcome.
