Our People
Open Support has a small staff base of both full and part time employees, as well as a strong and dedicated volunteer workforce of over 200 volunteers, who are integral to the delivery of many of our core services and operational areas. The organisation is headed by General Manager, Gary Sillett.
Open Support’s governing entity, the Open Support Committee, reports to the St Vincent’s Clinic Board and provides advice to the Executive Director of the Clinic, Mrs Michelle Wilson, and the General Manager of Open Support, Mr Gary Sillett, on matters relating to the organisation and its activities.
