Collette Sharbel-Merven

Specialist in Cognitive Behavioural Psychotherapy



Making the decision to attend therapy can often feel overwhelming and confusing. For most people therapy can, however, be an extremely positive and empowering experience that increases greater self-awareness and understanding.

I am a fully accredited and qualified Cognitive Behavioural Psychotherapist (CBT) with over 8 years of experience and specialise in working with adults. Being fully accredited implies that I have achieved the highest standard in my practice and that I adhere to stringent codes of professional practice and ethical standards.

CBT is an evidenced-based therapy and is recommended by NICE (The National Institute of Clinical Excellence). CBT has been proven to be extremely effective in the treatment of most problems we encounter. Being evidence-based means that I am able to incorporate a wide variety of established and researched psychological techniques in my practise and therapy with you. The effectiveness of these have not only been evidenced by extensive research but also by my own clinical experience of seeing what really helps people.

I have undertaken advanced training in a number of different Cognitive Behavioural Therapy approaches including Acceptance and Commitment Therapy (ACT); Compassion-Focussed Therapy (CFT), Couples Behavioural Therapy and Dialectical Behaviour Therapy (DBT) and Schema Focused Therapy.

My approach is open, informal, collaborative, empathic, warm and relaxed so as to enable a safe, comfortable and non-judgemental space to explore thoughts, feelings and unhelpful behaviours. I aim to provide a quality of therapy that I would be comfortable for my loved ones to attend. I value having honest relationships with my clients whilst always maintaining good rapport and trust, respect, integrity, and dignity. I am fully committed to providing an individualised, high quality therapeutic experience based on best practice and aim to prioritise the client and their needs.I value the quality of the therapeutic relationship with clients and firmly believe this to be an important contributor to the overall success of therapy and to the development of a positive and motivating therapeutic experience.

I consider you, the client, to be the expert who knows your own problems better than anyone. It is you who gives me insight into understanding the painful issues and difficulties you are experiencing. In your therapy and through increased self-awareness, I will guide, assist and support you to learn to take responsibility for improving the quality of your life by changing unhelpful patterns of behaviours and negative thoughts. I am fully committed to working with you to find realistic and long-term solutions to your problem as well as to develop and apply new skills and techniques.

I have a passionate interest in treating all anxiety disorders (social, generalised, health, specific phobias, OCD and panic), stress, habit disorders, eating disorders, body dysmorphia, depression, low self esteem issues (lack of confidence and self-worth), anger issues, assertiveness and sleep difficulties. I also work with couples and treat relationship and sexual problems.
