Maria (Mary) Katsarou has always been driven by a simple wish: to help people smile. As a Social Worker, Systemic Psychotherapist, and Certified Adult Educator, she approaches human vulnerability with deep respect, empathy, and care.

For more than three decades, she has worked on the front lines of mental health and social care, holding senior clinical positions at the 18 ANO Addiction Treatment Unit and supporting people in custody at the Korydallos and Avlona Correctional Facilities. These years of experience taught her the importance of serving as a bridge to recovery and reintegration, while inspiring her to expand her work into prevention through the education and ongoing support of parent groups in the Municipality of Elefsina.

Drawing on her extensive experience in systemic and family therapy, Maria supports individuals and couples in rebuilding their relationship with themselves and strengthening their connections with others. She is a member of the Hellenic Society of Systemic Psychotherapists (ELESYTH) and the European Family Therapy Association (EFTA), actively contributing to the ongoing development of the field.

Today, all of this knowledge, experience, and compassion come together in the work of Psy-Nest, where she offers meaningful support to people seeking greater self-understanding, emotional wellbeing, and personal growth.

At the heart of her work lies a simple yet profound belief: although people may be deeply wounded by life's challenges, when they are met with genuine safety, acceptance, and support, they have the capacity to heal, grow, and reconnect with their authentic selves.
