Liesl pioneered the person centred approach to art therapy and developed what we call the PCATS model. Liesl worked for 18 years as a school counsellor in  London, UK.  She was a counselling tutor for South West London College Counselling Courses for 10 years and for four years on the Westminster Pastoral Foundation Counselling Course. Liesl trained as an art therapist and was a fellow of the British Association of Counselling and Psychotherapy.  Wanting to bring a more person-centred facilitative approach into her practice of art therapy, Liesl founded the Person-centred Art Therapy Centre in London in 1985, offering certificate and diploma courses, workshops and supervision. The Person-centred Art Therapy Association (PCATA) later followed with the primary aim to develop practice through providing workshops and CPD support to practitioners. She wrote ‘Art Therapy – the Person-Centred Way’ – the first book on this approach in 1993, and Art Therapy Exercises in 2009.
