Dr Tessa Crombie

BSc. (Hons) D. ClinPsy.
Clinical Psychologist


Dr Tessa Crombie graduated from Leeds University with a BSc Hons in Psychology. Following her undergraduate degree, she went on to work as a support worker and an assistant psychologist in forensic and psychosis services. Tessa studied for her Doctorate in Clinical Psychology (DClin) at University College London (UCL), completing this in 2013. During this doctorate training, Tessa gained experience of working with adults and children with a range of emotional difficulties, Learning Disabilities, and physical health problems, using a range of therapeutic interventions (such as Cognitive Behavioural Therapy (CBT), Acceptance and Commitment Therapy (ACT) and Narrative Therapy). She also gained experience of conducting neuropsychological assessments.


Since qualifying as a Clinical Psychologist, Tessa has predominately worked within the NHS with children, adolescents and their families. This has included work within local Child and Adolescent Mental Health Services (CAMHS) and within schools. In addition, she has conducted research into improving the experience of NHS services for Children and Adolescents.

Current Practice

Tessa currently works as a Clinical Psychologist in an NHS local Child and Adolescent Mental Health Service (CAMHS) and in a more specialist Child and Adolescent Trauma and Anxiety Service. She is also working privately, offering therapy sessions to teach children and young people to manage a range of difficulties including Depression and Anxiety Disorders.

Therapeutic Practice

Tessa works with a range of evidence-based therapies in order to assist clients in achieving their individual goals. Her approach is predominately with Cognitive Behavioural Therapy (CBT). However, she also draws on Acceptance and Commitment Therapy (ACT) and Narrative Therapy within her work. She focused on providing short to medium term goal-based interventions, with the aim of providing clients with the necessary tools they need to overcome current difficulties, but also to develop lifelong skills and build resilience.

Additional Specialist Provision

Tessa has particular expertise in working with children and adolescents who have experienced trauma, including working with refugees and asylum seekers. She is trained and experienced in offering Trauma-Focused CBT (TfCBT), Narrative Exposure Therapy (NET) and Eye Movement Desensitisation and Reprocessing (EMDR) in order to treat children, adolescents and adults with Post-Traumatic Stress Disorder (PTSD). She also has extensive experience in treating a range of anxiety disorders and depression in children and adolescents.


Tessa also taught on anxiety disorders in children and young people on Doctorate, Masters and professional qualification courses at Kings College London, as well as providing supervision for trainee psychologists and other professionals with the NHS.


Tessa is registered with the Health and Care Professions Council. She has provisional accreditation with the British Association for Behavioural and Cognitive Psychotherapies (BABCP).

“My daughter met with Tessa for 6 sessions in total. She helped her understand what anxiety is, how it makes her feel and how normal it is. Most importantly, she made her realise that she is not ill and gave her a toolbox of how to manage her anxiety. Since seeing Tessa, my daughter is now happy to go to school and has definitely got her sparkle back!”
