About Me

I am a Clinical Psychologist based in London. I work with people facing addiction, mood disorders, conduct or behaviour problems and relationship issues. I provide psychological and diagnostic assessments, psychoeducation and adoption evaluations, and offer confidential online and in-person therapy across Greater London.

Approach

As my understanding of the psychology of human behaviour is predominantly rooted in a psychodynamic perspective, I mostly tend to follow an integrative psychodynamic approach. I am however also trained in other therapeutic modalities such as such as Cognitive Behavioural and Dialectical Behavioural Therapy (CBT & DBT), Brain Working Recursive Therapy (BWRT) and Motivational Interviewing (MI). I will therefore often draw on the techniques and principals of various approaches, so as to best meet the unique needs and preferences of my individual clients.

Services

I offer psychological assessment as well as long and short term psychotherapy so as to facilitate growth and the management of psychological distress/clinical disorders.

I believe psychotherapy to be a unique and collaborative process based upon the relationship between therapist and client. It allows an opportunity for one to openly explore and experience a range of thoughts and feelings in a safe and containing space, with someone trained to help understand and make sense of them. I believe in the power of being the expert in your own life and work from a person centred approach where the client’s needs are addressed with non-judgement, understanding, empathy and confidentiality. Through this, one can begin to change problematic behaviours, thoughts and emotions; gain further potential and productivity; as well as develop improved insight and meaning whereby increasing overall quality of life and personal growth.
