Meet Our Team

Our therapists hold qualifications beyond the requirements of the professional bodies and in a range of different approaches and techniques.

About Us

As psychotherapists living and working in London, we have become increasingly aware of the challenges and distress faced by many children, teenagers and their parents; distress caused by things such as family breakdown, school pressures, social media, relationship challenges and the impact of the pandemic.

We have set up TeenMatters to offer specialist support to those at the beginning, middle and end of adolescence (now understood to take place between the ages of 10-24), as well as to parents supporting their children through this period of transition.

We are passionate about the work we do and are 100% committed to the people we work with, many of whom say they appreciate the warmth, authenticity, compassion and sense of humour that we bring to our work.

Our Expertise and Experience 

As psychotherapists, we have a wealth of experience within a broad range of settings: mental health, psychiatric, corporate and social settings.

We are committed to ongoing clinical development, training and supervision and working as a team to support each other, in order to be able to offer the highest standards of care to our clients.
