Who are we


GISDA is a people led organisation which values its staff, trustees and stakeholders. We believe that people are the best asset of any organisation.

Our staff and trustees are passionate about supporting the young people we work with and aim to change their lives for the better.
We know that we have succeeded when we see the young people that we have supported being able to live independent and fulfilled lives.
All of our staff receive regular training for the requirements of their job and therefore fully understand the needs of our service users and stakeholders.
Our Board of Trustees meet regularly to govern our organisation. All of the Board members are committed to our aims and objectives and are selected for the skills and experience that they can bring to benefit our organisation and make a difference.
The daily management of our organisation is the responsibility of our Management Team which is led by the Chief Executive.
