“I don’t just advise. I transform services, people, culture and outcomes.”



My Journey in Care
Seventeen years ago, I entered the world of care as a student nurse.
I didn’t arrive through theory — I arrived through graft:
***Carer → senior carer → staff nurse → unit manager → clinical lead → deputy manager → registered manager → regional manager → consultant.
I’ve lived this sector from every angle, from hands-on personal care to leadership, governance and regulatory oversight.
I’ve worked alongside broken teams, frightened managers, overwhelmed owners, shattered confidence, failing inspections, safeguarding pressure, burnout, exhaustion and fear.
And I’ve also seen what happens when hope returns.
When direction returns.
When leadership strengthens.
When standards rise.
When people believe again.
That’s where my work lives.
Why I Founded Mareric
I created Mareric because I realised something important:
Care services don’t struggle because people don’t care.
They struggle because people don’t feel supported.
Mareric gave me the freedom to step into services exactly when and where I am needed, not tied to a job title, a building, or a boardroom, but driven by purpose, clarity, impact and integrity.
It allows me to bring strong leadership, clear direction, system strength, accountability, compassion and vision into environments that feel lost, stuck or overwhelmed.
Mareric isn’t “just consultancy”.
It is a practical, personal, powerful partnership.
A chance to prove that:
✔ change is possible
✔ confidence can return
✔ outcomes can be achieved
✔ and there is always light, even when everything feels like it is falling apart
