Managing Partner












DR ALISON Sillence

Associate Clinical Psychologist









DR Gina Gómez de la Cuesta

Associate Clinical Psychologist



With a career in the NHS, both as a Research Psychologist, and later as a Clinical Psychologist, Alastair has gained considerable experience in a number of different areas of psychological theory. After completing a degree in Psychology at the University of Leeds, Alastair worked in research with the Medical Research Council and later the NHS. Concerned with projects involving neurodegenerative conditions such as Alzheimer’s disease, and based at the internationally recognised Institute for Ageing and Health, and the Department of Psychology at the University of Newcastle, Alastair completed a PhD in the Neuropsychology of Dementia where his research investigated the different aspects of cognitive functioning in different forms of dementia.

After completing his PhD in the NHS, Alastair progressed to completing a three year Doctorate in Clinical Psychology at the Institute of Psychiatry, King's College London, before starting work in London at the South London & Maudsley NHS Trust, working with the very diverse adult population of South London. Moving to North London and Camden and Islington NHS Trust brought Alastair further knowledge of the everyday stresses and strains that people experience in inner city areas where he worked with people who were concerned about their memory in the London Borough of Camden.

Following his time in London, Alastair moved to East Anglia and worked for a number of years in three local NHS Trusts, most recently at Cambridgeshire and Peterborough NHS Trust as a Senior Clinical Psychologist and NHS Manager. He now works entirely in the private sector and specialises in both one-to-one therapy and working with therapy teams and Case Managers to ensure that patients reach their maximum potential following illness or injury.

Alastair is registered with the HCPC and is a Registered Chartered Clinical Psychologist. He is also an Associate Fellow of the British Psychological Society.


Alison completed her first degree at Cambridge, with further study at the Open University. Following the successful completion of her Clinical Psychology training at the University of East Anglia, Alison started work with Cambridgeshire and Peterborough Foundation NHS Trust. Working in a Cambridgeshire-based community mental health team brought Alison into close contact with older adults struggling with a range of mental health problems, often alongside physical health issues. Through this role, Alison also gained considerable experience working alongside other health care professionals where she lead in the management of often complex mental health presentations. Additionally, Alison has experience of supervising trainee Clinical Psychologists and student nurses.

Currently Alison works part time as a Senior Clinical Psychologist at Addenbrookes' Hospital and part time with Meridian Psychology Cambridge. Her NHS role involves work with adults who are experiencing chronic pain, often alongside long term health conditions. Alison's work focuses upon helping people gain confidence and feel more engaged with life while managing pain and symptoms. She uses a range of therapeutic approaches, including compassion-focused therapy and mindfulness-based approaches as well as cognitive behavioural therapy, and it is this wealth of experience that Alison now brings to Meridian Psychology Cambridge.

Alison is is registered with the HCPC and is a Registered Chartered Clinical Psychologist.


Gina completed her Clinical Psychology Doctorate at the University of East Anglia in 2017. Her expertise lies in the area of children and families, with a particular interest in Autism Spectrum Disorders. After graduating in Experimental Psychology from the University of Oxford, Gina trained to be a secondary school teacher. Wishing to be more involved with academia and psychology, Gina then completed a PhD at the Autism Research Centre at the University of Cambridge, looking at using LEGO® bricks to support social interaction in children with autism. She has since worked at the National Autistic Society prior to training as a Clinical Psychologist.

Gina currently works part time for Hey! Cambridge, a social enterprise dedicated to supporting children and young people with mild and emerging mental health problems. She has also set up Bricks for Autism, offering professional training in LEGO®-based therapy. Clinically, Gina uses systemic approaches alongside an understanding of child development and neuropsychological assessment to develop a holistic picture of a child’s strengths, vulnerabilities and needs. She is passionate about getting the right understanding and support for a child to help them fulfill their potential.

When not involved with all her other projects, Gina works with Meridian, supporting children, their families and their therapy team to ensure that children get the most from life.
