The Fellows, established in 1963, are the guardians of the Trust Deed. Members of the Sergel family are Fellows and appoint their successors. Other members are people who have been actively involved in Southwell life in a variety of ways and are invited to join the group. The Fellows are an important link between the school of today and school of yesteryear. They remind us of the school's traditions and values and what we strive to instill in the next generation.
The Fellows gather annually on Founders' Day (1 November) which in the church calendar is called 'All Saints' Day'. The Fellows' responsibilities include being consulted prior to the appointment of the Principal or any new board members. Each year one of the group is elected as Warden of the School.
