Quotes from young people and their families

“The staff have always been helpful and friendly and have always done the best for me. They have helped me through some hard times and helped to make them easier.” - young person

“Being treated as an individual in a supportive caring way has us move forward” parent

“This service is fantastic - there is nothing that I can say is not great - the support for both my daughter and me and her dad has been life changing - we have learnt how to manage and that is brilliant” - parent

A young person describing her experience with our service in contrast to her previous experiences with other professionals and adults who have been dismissive of her mental health problems:

“Acceptance of mental health issues is vital, it’s like saying to somebody with a broken limb ‘get on with it without any help.

Feedback from National Children’s Hospital Peer Review of Paediatric Acute Care Services for Children and Young People: Evelina London Children’s Hospital:

“The panel was of the view that the CAMHS provision at Evelina London was of the highest quality and could act as an exemplar for other areas.

"It was noted how closely Evelina London works with South London and Maudsley NHS Foundation Trust. The onsite provision is led by a consultant child psychiatrist. A CAMHS clinical nurse specialist available on-site Monday to Friday to provide clinical support and training. Members of the panel were advised that the general paediatrics’ staff regard themselves extremely lucky to have such support.”
