Our trustees are a small group of passionate people who care deeply about what we do and why it matters. They support the charity by offering guidance, sharing their experience, and helping us make strategic decisions about our future.
Our trustees are volunteers. They work behind the scenes to keep the charity running well, making sure we stay true to our values and focused on supporting people with DS and their families in Oxfordshire.
