“Lumis” — from the Latin lumen (light) and the old Scots -is, meaning that which endures.
Not the flash of revelation. The steady, quiet light that sustains through the storm.
Values
Steadiness
A quiet, reliable presence that steady change requires — not the flash of a quick fix, but a light that stays on.
Compassion
Warmth paired with expertise: the credibility of clinical training held alongside the approachability of a trusted guide.
Excellence
A grounding in evidence and professional standards, underpinned by HCPC and BABCP registration and an academic background in clinical psychology.
Authenticity
Saying what is meant, and meaning what is said — no jargon for its own sake, and no promises that can't be kept.
Discretion
Psychological work is personal, and treated that way — in communication, in the handling of client information, and in how the practice is presented publicly.
Resilience
Favouring strong foundations and steady effort over short bursts — working smart rather than hard, and avoiding the boom-and-bust cycles that wear people down.
"What I valued most about this therapeutic relationship was Marie-Claire's high level of professionalism, preparation, and genuine commitment to my healing. She never seemed to run out of ideas on how to support me, whether through new exercises, carefully chosen readings tailored to my specific challenges, or by confidently guiding me to the next step of the healing process. Every session felt like a safe space where I was truly heard, understood, and respected. I would wholeheartedly recommend Marie-Claire's services to anyone seeking professional, thoughtful, and genuinely caring psychological support." — Person with IBS, generalised anxiety and ADHD · 5 months of therapy
