Most people who reach me have tried other routes. They arrive knowing something is wrong and suspecting that the right kind of help could change everything. They are usually right.

About Guy

A therapist who has
earned his expertise.

I began my clinical career in the NHS in 2016, working within high-pressure acute settings that demanded both rigour and adaptability. That foundation — the discipline of evidence-based practice applied to complex, real presentations — informs every session I offer privately today.

I now work exclusively in private practice, online and one day per week in person in NW London. My patients are often high-achieving professionals who have, until now, managed their difficulties alone. They come to me when managing alone is no longer enough.

I hold a diploma in CBT from Royal Holloway, University of London, and am fully accredited by the British Association for Behavioural and Cognitive Psychotherapies (BABCP).

Areas of Focus

Where I do
my best work.

CBT is a structured, evidence-based approach — but structure alone does not create change. I bring 15 years of clinical depth to each of these areas, and I am specific rather than general in how I treat them.

01
OCD

Specialist ERP-based treatment for all OCD subtypes, including contamination, harm, and intrusive thought presentations. One of my primary areas of clinical expertise.

02
Anxiety Disorders

GAD, health anxiety, social anxiety, panic disorder and phobias. Evidence-based protocols tailored to the specific anxiety presentation — not a generic approach.

03
Perfectionism

Clinical perfectionism that has crossed from asset into obstacle. Particularly common in senior professionals and high-achievers navigating pressure from multiple directions.

04
Executive Burnout

Burnout at senior level is not a motivation problem. It is a clinical presentation that responds well to structured CBT intervention. I work with this frequently.

05
Depression

Behavioural activation, cognitive restructuring and relapse prevention for clinical depression, including depression comorbid with anxiety or burnout.

06
Trauma & PTSD

Trauma-focused CBT and EMDR for single-incident and complex trauma, including PTSD. EMDR is a NICE-recommended, evidence-based treatment that works where talking alone often cannot.

07
ADHD Support

CBT adapted for adults with ADHD — managing dysregulation, procrastination, and emotional reactivity using evidence-based, ADHD-specific techniques.

How I Work

A clear process.
No ambiguity.

01 —
Initial Consultation

A 50-minute assessment session where I listen carefully, ask precise clinical questions, and form a clear picture of what you're experiencing and what treatment would look like.

02 —
Formulation

I develop a personalised CBT formulation — a clinical map of your difficulties, their origins, and the mechanisms maintaining them. This is the foundation of everything that follows.

03 —
Structured Treatment

Weekly 50-minute sessions, online or in person. CBT is active, structured, and collaborative. Most courses run 8–20 sessions depending on presentation and goals.

04 —
Relapse Prevention

The final phase consolidates your progress and builds the tools to maintain it. Good CBT ends with you needing less of it — and knowing how to use what you've learned for life.

"He helped me understand, for the first time, not just what I was doing — but why. That distinction changed everything."

Patient Perspectives

What people say
after treatment.

★★★★★

"I came in deeply sceptical. I had tried therapy before and found it frustrating. What happened with Guy was a life-changing internal shift I simply had not imagined possible."

OCD · London

★★★★★

"After years of managing on my own, I finally have tools that actually work. Guy was precise, warm, and completely non-judgemental. I wish I had done this sooner."

Anxiety & perfectionism

★★★★★

"Guy understood my presentation at a clinical level that no one else had. He explained the mechanism of what was happening in a way that immediately made the treatment feel coherent."
