Dr Gemma Allison - Consultant Clinical Psychologist

★★★★★
You give a world class professional service. Thank you very much for your openness, engagement, and continued support.

B.Sc(Hons), DClinPsy, PGDip CAT, HCPC Registered, ACAT accredited.

Dr Gemma Allison qualified as a Clinical Psychologist in 2008. Gemma has experience working in NHS mental health services for adults and adolescents. She has specialist experience of working with clients experiencing a first episode of psychosis and clients experiencing an acute mental health crisis. Alongside her role at Harley Therapy, Gemma continues to work in the NHS leading a psychology service for acute mental health wards and crisis assessment and treatment teams.

Gemma's clinical psychology training has provided her with the ability to use a range of therapeutic models. She has undertaken additional training which has provided her with specialist knowledge and practice of cognitive analytic therapy (CAT). She is a qualified CAT practitioner accredited by the Association for Cognitive Analytic Therapy.

Gemma has worked in private practice since 2004 providing psychological assessment, formulation and therapy to adolescents, adults and families. Her approach is based on an individual assessment and understanding of someone's presenting difficulties to inform the therapeutic approach needed, this includes using an integrative approach. In using an integrative approach a range of therapeutic models (e.g. cognitive behavioural, systemic, narrative) and psychological theory are drawn upon.

Gemma is skilled in working with clients to address a range of psychological difficulties these include anxiety, OCD, phobias, panic, stress, depression, personality disorder, self-harm, interpersonal/relationship difficulties, self-esteem issues, anger, eating disorders, traumatic experiences, abuse, psychosis and bipolar affective disorder.

She believes in working collaboratively with clients within a time-limited framework addressing an agreed focus in therapy.
