Working with Mr. Tristam has given me clear perspectives on some issues I've been bothered by. He listens well and tries to show empathy whilst still compassionately telling the truth about what I can do to improve my condition. His approach to therapy is one I've benefitted from and I happily recommend him to people looking for competent therapists.
