Constantinos Leftheriotis CBT Therapist

About Me

Hello, I'm Constantinos or Costa for short and I’d love to be your therapist. Helping clients navigate life’s challenges is my great honour and I’m ready to put my solid educational foundation and extensive training to work in your life.


Using the evidence-based strengths of CBT, I ensure each session is both effective and personally tailored to you. Together, let’s create a powerful transformation in your life and enable long-lasting, loving relationships.

In our sessions, I’ll start with the principles of CBT. From there, I’ll layer in additional modalities as needed like Gestalt and Attachment Theory. This holistic approach allows us to explore the past, all while creating effective pathways towards a brighter future. 


In each session, you’ll be welcomed into a confidential space where every thought and emotion is welcomed and acknowledged openly.


My practice is focused on adults and couples; providing counselling sessions in English or Greek, whichever best suits your needs. I'm here to support you on your journey to wellbeing. So, if you're ready to make a positive change, you only need to take one tiny step and get in touch today.
