Specialist Practitioners

Lead Practitioners.
Matched to your journey.

Every practitioner at Lyceum holds a specialist brief. You will never be assigned a generalist. When you complete your clarity call, you will be matched with the practitioner whose specific expertise maps directly onto your situation.

Sarah Chen

Lead ADHD Systems Practitioner

MSc Cognitive Neuroscience · BABCP Accredited

Sarah works exclusively within the Neuro-Sovereignty Protocol, specialising in the Biological Baseline pillar — sleep architecture, nutritional neuroscience, and movement-based cognitive enhancement. She has helped over 200 adults with ADHD build sustainable daily systems that work with their brain, not against it.

Specialisms

Sleep & circadian rhythm optimisation
Nutritional neuroscience for ADHD
Executive function coaching
ADHD Mastery

Marcus Webb

Cognitive Mastery Practitioner

MSc Counselling Psychology · EMDR Certified · ACT Trained

Marcus specialises in what he calls 'the invisible weight' — the chronic low-grade stress, perfectionism, and identity confusion that high-functioning adults carry silently for years. His approach combines EMDR for trauma processing with ACT-based values clarification to help clients finally move forward.

Specialisms

High-functioning anxiety & burnout
Identity and self-worth rebuilding
EMDR trauma processing
Cognitive Mastery

Dr. Amara Osei

Relational Repair Practitioner

DClinPsy · Gottman Level 2 · EFT Certified

Dr. Osei works with couples who have reached the point of quiet desperation — where the arguments have stopped not because things are better, but because both partners have given up trying. She uses a structured Gottman-EFT hybrid to rebuild the emotional safety that makes real intimacy possible again.

Specialisms

Emotional disconnection & stonewalling
Rebuilding trust after conflict
Intimacy and vulnerability work
Relational Architecture

Tom Hargreaves

Performance & Resilience Practitioner

MSc Sport & Exercise Psychology · CBT Accredited

Tom bridges the gap between clinical psychology and performance science. He works with adults who are high-achievers on the outside but running on empty on the inside — helping them build genuine resilience rather than the brittle coping strategies that eventually break down under pressure.

Specialisms

Performance psychology
Stress resilience & recovery
Goal-setting for neurodivergent adults
Individual & ADHD
