Whether you come to therapy as an individual, couple, as parents, or as a family, I aim to create a space that feels safe to explore the issues you’d like to address. I work flexibly, collaboratively and at a pace that feels right to you.  With extensive clinical experience, I use a range of evidence-based approaches and always strive to offer the highest standard of individualised care.
