About me

I am an experienced and friendly Clinical Psychologist with over 18 years of professional experience supporting individuals across the lifespan in the areas of neurodiversity and mental health. My work focuses on providing evidence-based psychological assessment and therapy, with particular expertise in autism, ADHD, learning differences, and related emotional and behavioural challenges. Throughout my career, I have worked with children, adolescents, and adults, helping clients better understand themselves, build resilience, and develop practical strategies for everyday life. I am passionate about creating a supportive, respectful, compassionate and neuro-affirming space where individuals feel heard, empowered, and understood. My approach is collaborative and tailored to each person’s unique needs, combining clinical expertise with compassion and a deep understanding of the complexities of neurodivergent and mental health experiences. I am committed to promoting wellbeing, self-awareness, and long-term personal growth through meaningful therapeutic work. As a clinical psychologist, I work empathically, with clear direction, taking an active approach to therapy. Treatment will always be tailored to you and your specific needs, hopes and goals. I abide to clear codes of conduct and only offer therapies that have a strong evidence and research based. I can also offer the Neurodiversity Coaching to children, young people and adults. For younger children, this support may be directly with the child, or if more appropriate I will work with parents to help them to better support their child. We will explore together your unique strengths and challenges, by setting clear and realistic goals and developing practical skills to navigate any areas of difficulty. I am fluent in Greek, English and French and therefore I can offer therapeutic work in these languages if required.
