PhD C., PGCert, MSc, MSc, PGCert, MSc, BA –

I am a Senior Systemic and Family Psychotherapist, Psychologist and a qualified / registered Systemic Supervisor. I offer psychotherapy to individuals, couples and families. I have extensive experience working with diverse family structures. I am based in London and in Athens.

I have lived in Greece, the Netherlands and the United Kingdom and I am fluent in English, Greek and German. I am experienced working with families from different ethnic and cultural backgrounds and take time to connect with the culture and social context relevant to the clients and their presenting difficulties.

I completed my clinical training in Systemic and Family Psychotherapy (MSc and PGCert with Distinction) at the Institute of Psychiatry, Psychology and Neuroscience at the Maudsley, Kings College London as a Kings College London Scholar. In addition to my specialist training I have degrees in Psychology (MSc), Communication Theories (BA) and Organisational Management (MSc) and I’m interested in the relevance of each discipline to the other. I hold a further postgraduate qualification (PGCert) in Systemic Family Therapy Supervision, Consultation and Training from the Tavistock Centre, in London.

Moreover, I’m currently studying towards a PhD in Psychology through King’s College London (Institute of Psychiatry, Psychology & Neuroscience), researching the relationship between childhood gender identity / gender non-conformity and eating disorders in adolescence, as a Leventis Foundation Scholar.

I currently work as a Senior Systemic & Family Psychotherapist at the Maudsley Centre for Child & Adolescent Eating Disorders (MCCAED). I have a strong clinical background working with young people and adults who present with eating disorders, often anorexia nervosa, bulimia nervosa or ARFID, as I have also worked clinically with eating disorders in Royal Free Hospital Eating Disorders Service and in Homerton Hospital. I am experienced in facilitating individual, family and multi-family therapy sessions and offering psycho-education to all those involved, including other professionals.

I’m a founding member of the International Association of Therapists for Desisters and Detransitioners, which is an organisation supporting people across the life-span who stop either the social or medical transition in relation to their gender.

Alongside my other National Health Service posts, I worked for four years at the Tavistock Centre in London, as a Highly Specialist Systemic and Family Psychotherapist for the Gender Identity Development Service (GIDS). GIDS is a national specialist child and adolescent health service supporting young people and families who present with challenges in relation to the development of their bodies and identity, including sexuality and gender identity. There I established and led the first NHS Family Therapy & Consultation Service in London for gender non-conforming, gender diverse and gender questioning young people and families and I was a joint coordinator of the service’s continuous professional development course for external agencies and professionals. I have significant experience working with individuals, couples, or families who identify in LGBTQI+ identities from different cultural backgrounds. Alongside GIDS, I was an Honorary Systemic & Family Psychotherapist in the University College London Hospital (UCLH) in the paediatric endocrine liaison clinic.

In 2020 I served as a scientific advisor for the production of the podcast series Sex Education, developed through the collaboration of Onassis Stegi and POD.GR, which delivered 12 psycho-educational podcasts focusing on developmentally-appropriate sex education for youth 16+. The project focused on consulting with producers, presenters and developers and delivering current evidence-base / data and approaches related to contraception, sexuality, gender identity development, bullying, body image difficulties, sexually-transmitted infections etc.

Apart from my clinical work, I also work as a Visiting Lecturer and Placement Supervisor for the systemic therapy training at the Institute of Psychiatry, Psychology, and Neuroscience at the Maudsley, Kings College London. I am active in teaching, training and research, focusing on different areas on mental health, such as eating disorders, gender identity, sexuality, attachment, affective disorders, and on specific therapeutic interventions, such as systemic and family psychotherapy.
