About me

I am a Clinical Psychologist (DClinPsy, BSc Hons) and HCPC-registered practitioner with over 15 years of clinical and academic experience.

In addition to my private practice, I work as a Guest Lecturer on the Doctorate in Clinical Psychology at Royal Holloway University of London and as a tutor with the Association of Psychological Therapies.

I offer therapy sessions and comprehensive assessments for autism and combined autism and ADHD, working with adults, children, and young people.

My team and I currently have availability for autism and ADHD assessments in St Margaret’s and Clapham.

Autism and ADHD Assessments

I provide autism assessments and combined autism and ADHD assessments for both children and adults. I also offer initial neurodiversity consultations to explore individual needs and to think through the next steps.

All assessments are conducted as part of an experienced and compassionate team, following best-practice guidelines, including NICE recommendations and the UK Adult ADHD Network (UKAAN) Quality Assurance Standards.

Our approach is neuroaffirming, ensuring that each assessment is thorough and centered on understanding an individual’s unique strengths and challenges. We work collaboratively with clients to develop tailored, practical recommendations that truly support their needs and well-being.

We understand that, when navigating the path of an assessment for yourself or for your child, there can be a lot to consider. We are committed to providing clear information about what we do, helping you feel informed and supported throughout the process. If you’d like to learn more about how our assessments work, please get in touch.

Therapeutic Values and Practice

My first priority is to create a safe and supportive therapeutic space where clients feel heard and understood. I provide a compassionate and empathic outlook, approaching difficulties with kindness and curiosity.

Together with clients, we build a shared understanding of strengths, challenges and what has led to these and keeps them going. I then work with clients to develop a tailored therapeutic plan. This typically utilises a combination of skills and overall therapeutic concepts, for example self-compassion, stress/anxiety management, building positive self-identity and maintaining healthy relationships.

As an experienced Clinical Psychologist, I adapt my approach to each individual’s goals and values, drawing on evidence-based therapeutic models such as Compassion-Focused Therapy, Narrative Therapy, Cognitive Behaviour Therapy, and Dialectical Behaviour Therapy.

I have found great value in noticing personal narratives - the stories we tell ourselves about who we are and how we relate to the world. Together, we can work on reshaping these narratives in ways that foster confidence, self-acceptance, and overall well-being. By integrating self-compassion into my practice, I aim to foster the development of long-lasting principles and skills that will provide my clients with long-term benefits.

Testimonials

Therapy:

"Working with Kat had a hugely positive impact on my life in many ways. I learned valuable tools and thought processes that helped me navigate some difficult circumstances, and these are skills that I still use today.”     PA, 34, London

Autism Assessments:

“Kat’s interview style was special. There is something about going to do an assessment, initially being apprehensive, but then forgetting about it because the interviewer brings you into her world, puts you at ease. You feel safe.”     Business Consultant, 38, London

Why the name Sonoro? 

 Why the Name Sonoro?
The name of my practice is inspired by the Italian musical term "sonoro," which means to play or sing with depth, richness, and meaning. This resonates deeply with my approach as a therapist, and it also reflects my personal love of music and my previous life as a musician.
