For counselling, Sian is interested in working with young people aged 12 to 18 years. She works with children and adolescents who may require support regarding existing diagnoses such as anxiety, depression, autism or ADHD, as well as supporting the development of social skills, emotional regulation and study skills. Sian provides a warm and supportive environment where each young person can feel comfortable to discuss their concerns and develop skills to manage their challenges now and in the future. Sian typically draws on cognitive behavioural therapy (CBT) and acceptance and commitment therapy (ACT) in her work.
