About

Len Kleanthous is an experienced psychotherapist with a career spanning over two and a half decades in addiction counselling and more than a decade in mental health. 

As well as addiction, Len is skilled in addressing challenging thought processes and negative beliefs that influenced their moods and behaviours. To further enhance his therapeutic approach, Len pursued training in Cognitive Behavioral Therapy (CBT) and Dialectical Behavioral Therapy (DBT) Skills, which he integrates into his therapeutic work.

Len enjoys working in one-on-one therapy, and he practises as a relational therapist. His passion extends to group therapy sessions, where he conducts psychoeducational groups on various topics, including self-esteem, emotional awareness, self-care, and financial well-being, as well as DBT skills training. He firmly believes in the power of these group dynamics to foster personal growth and positive change.

Throughout his career, Len has continuously nurtured his professional development and psychotherapy skills. He remains deeply committed to helping his clients enhance their self-worth, overall well-being, and capacity to make meaningful life changes.

In the area of addiction recovery, Len is recognised as a specialist with over 15 years of experience in working with individuals facing addiction and dual diagnosis challenges, as well as their families. He brings a wealth of coping skills and interventions to any team or service dedicated to assisting clients in their pursuit of change, personal growth, and a life free from addiction.

Len is known for his compassion, empathy, and encouragement, which he offers to clients throughout their recovery journeys. His consistent support has been a source of inspiration and transformation for many individuals seeking recovery.

“Evidence-based care tailored to each patient — taking the time to explain options and shared decisions.”

— Len Kleanthous
