Hello. I am Ondine Smulders. Following my own experience with therapy, I decided to retrain to become a fully qualfied psychotherapist and existential analyst. Five years of training at Regent's University have led to a postgraduate diploma (PgDip) in Integrative Psychotherapy and Counselling Psychology and an Advanced Diploma in Existential Psychotherapy (ADEP). 


Therapist experience: I have worked as a therapist since 2012, providing both long-term and short-term individual and group psychotherapy. I have worked in the NHS, at Mind, at the Woman's Trust, and in private practice. As well as running counselling seventeen, I am an associate at Therapy Harley Street, and work as a psychotherapist and group facilitator at Breast Cancer Haven.


Accreditation: I am accredited through the UK Council for Psychotherapy (UKCP) and abide by its code of Ethics and Conduct. As part of their standards, my clinical work is overseen by supervisors who are also UKCP-accredited and I invest in continued personal development and training. I am a member of the Society for Existential Analysis.


Background: Before retraining as a Psychotherapist and Existential Analyst, I worked for more than a decade in investment banking followed by more than a decade as an analyst in a think-tank/publishing house. My banking and publishing jobs have provided me with first-hand experience of the highly competitive and stressful nature of these work environments. My business interest and involvement continues through a private-sector supervisory board role. 


Languages: I am  a multi-lingual psychotherapist. I am able to work in English, Dutch, Spanish and French.
