Dr Rebecca Williams 
BSc DClinPsy 

A highly specialist Consultant Clinical Psychologist, with over 22 years expertise in working with adults and children with learning disability and neurodevelopmental disorders. I’ve worked within the NHS and privately conducting complex assessments, formulations, and interventions, as well as providing clinical leadership to Learning Disability, Children’s Disability Services and Neurodevelopmental Disorders services within the NHS.  

I am registered as a Practitioner Psychologist with HCPC, an Executive Coach with Association for Coaching, am a member of the Association of Clinical Psychologists (ACP), and have been working at Consultant level for the last 15 years.

I’m experienced in adapting therapies such as Cognitive Behavioural Therapy (CBT) and Acceptance and Commitment therapy (ACT) to the needs of adults and young people with a learning disability or who are neurodiverse.

The Team

As part of your or your child's assessment, it is important to look at social use of language, and check for any underlying language problems.  We have two experienced Speech and Language Therapists who are skilled at assessing subtle difficulties in understanding or self expression that can be part of the picture in ASD or other developmental problems.

We also have an Occupational Therapist on the team who can offer dyspraxia assessments, sensory needs profiling, and help with adapting daily routines to minimise sensory overload.

My approach to clinical work and assessment focuses on working together in partnership. I work collaboratively to complete complex assessments (including neuro-developmental assessments), formulations, and make practical recommendations to help you and/or your child.

I am also a qualified mindfulness teacher practitioner and supervisor. I’m experienced in delivering and adapting a range of therapies including Dialectical Behaviour Therapy, Cognitive Behavioural Therapy, Compassion Approaches and Mindfulness-based interventions. I have published research in the area of mindfulness and mental health.

I’m a highly specialist Speech and Language Therapist with over 20 years’ experience of working with children and adults with learning disability and neurodevelopmental disorders.

I can provide comprehensive assessment of language and communication, leading to a detailed report and communication profile. This will help you and others to gain a clearer understanding of your child’s language and communication needs and what support and strategies they need to communicate to the best of their abilities. A SALT assessment is often integral in identifying hidden language and communication difficulties that contribute to misunderstandings or behaviour that challenges. I can liaise with agencies and provide bespoke training packages around an individual to help those who support them understand their needs.

I work closely with Dr Rebecca Williams in providing autism assessments using Autism Diagnostic Observation Schedule (ADOS)
