Dr Mari Campbell is the joint lead for psychological therapies and counseling across the Royal Free London NHS Foundation Trust, with a focus on ensuring that patients can access holistic care that considers their mental and physical health and supports recovery where possible.

She works clinically in the department of clinical immunology, where she works with individuals, families, and teams, offering consultation and individual therapy to patients living with rare long-term physical health conditions.

Across her 15 years of clinical practice, Mari worked for several years in child and adolescent eating disorder and adult weight management services, before moving to the Royal Free London to set up the first specialised psychology service for adults with immunodeficiencies in the UK. She has published widely, teaches a variety of professional and non-professional groups, and is research active, focused on quality of life and mental health for patients living with rare disease.
