By Art Therapy in Ballydehob, West Cork. Marika O'Sullivan

I am an art therapist based in Ballydehob West Cork. My background is in art and design, but I have also worked therapeutically with people for over 20 years. I also have many years experience of creative group facilitation and working in schools with art and design projects. I am currently Art Therapist in ARC,cancer support in West Cork and on the Cosceim panel working with young people in Direct Provision. Other experience includes working with adults of all ages, children and more specifically with adolescents and families who are having difficulties while at this transitional stage. Art Therapy allows creative solutions to difficult situation, the process builds resilience and improved coping skills, bringing joy and the potential to thrive creativity back into one's life.
