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.
Lead ADHD Systems Practitioner
MSc Cognitive Neuroscience · BABCP Accredited

She has helped over 200 adults with ADHD build sustainable daily systems that work with their brain, not against it.
Specialisms
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
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
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.
