Dr Elliott is a HCPC and BPS registered Doctor of Forensic Psychology with an interest and expertise in the assessment of high-risk offenders both in custody and in the community, interrogative suggestibility and criminal culpability. Dr Elliott has gained a significant range of experience practicing in a variety of settings, including secure units, police stations, private practices, courts and prisons. This has afforded Dr Elliott the opportunity to work with a wide range of professional services, to serve clients from a variety of backgrounds and cultures with diverse clinical presentations. She is familiar with a range of forensic assessment tools, including those with a focus on sexual and violent risk, personality and psychopathy, interrogative suggestibility, malingering and cognitive functioning.

Dr Elliott’s experiences have enabled her to acquire an advanced ability to build rapport and retrieve and weigh information provided in clinical interview. Clearly, being able to engage with clients in such fashion that one can gain an accurate picture of their beliefs understandings and motivations is essential if one is to manage and understand risk effectively. This is also important for building and sustaining an open and trusting therapeutic relationship that will enable the client to develop in an adaptive fashion.
