Who We Are
Trinity was founded by three people with one shared belief: everyone deserves safety, dignity, and the chance to move forward. Our work is grounded in decades of experience across housing, local government, and people‑centred services — and in a deep commitment to supporting people through crisis, transition, and the complexities of the housing system.
What unites us isn’t just our backgrounds, but our purpose. We believe in:
- Human‑first practice — dignity and respect at the centre of every decision
- Partnership — because lasting change happens together
- Positive outcomes — not quick fixes
- Listening deeply — especially to voices too often overlooked
Together, we bridge systems, simplify complexity, and design support that genuinely helps people move forward. We’re here to make a difference in the moments that matter.
Below, you’ll find our individual profiles — three people, one shared mission.
Craig Coombs
Founder and Chair
Craig brings to Trinity something rare in the charitable and housing sectors: the instincts of a serial entrepreneur who builds organisations that work, scale, and last — and who measures success in the difference made to people’s lives.
His leadership is rooted in a belief in community‑led regeneration and in every person’s right to a supported second chance. That conviction shapes how he leads, what he invests in, and why Trinity matters to him.
As Managing Director of Wallice Main and founder of Lilyalex, Craig works at the intersection of commercial discipline and real‑world housing need. His experience spans manufacturing, temporary accommodation, care homes, and growing companies across B2B and B2C markets, including the demands of digital‑first commerce.
Across all his ventures, Craig specialises in building organisations ready for long‑term growth — always grounded in the communities they serve. As Chair of Trinity, he brings entrepreneurial drive, sector insight, and a deep commitment to meaningful, community‑shaped change.
Dr Amanda Milliner
Founder and Chief Executive Officer
Amanda brings over two decades of experience across public, private, and third sectors — from the NHS and local government to housing, construction, and community development. As CEO of Trinity and the Trinity Foundation, she leads with a clear focus on the people most often overlooked: those in temporary accommodation, facing homelessness, or searching for stability.
Her doctorate in organisational and community engagement shapes how she works: always asking who isn’t being heard, and designing services around the human being, not just the housing need.
Before Trinity, Amanda co‑founded Avanti, working with boards and leadership teams across the UK and internationally to build the culture, strategy, and behaviours that make real change possible. She brings that strategic depth directly into Trinity, ensuring the organisation is built to last — and built to matter.
Qualified in mindfulness, CBT, REBT, and a range of psychometric tools, Amanda understands systems and people. Her work with women in leadership and her board roles across media, community, and reform organisations reflect her commitment to empowerment and integrity.
At Trinity, her purpose is simple: create the conditions where people have not just a roof, but a real chance.
Dr Jonathan Huish
Founder
Jonathan founded Trinity on a simple conviction: homelessness is a systems failure — and the response must be just as strategic, human, and ambitious as the challenge itself.
He brings over 25 years of leadership across housing, local government, public finance, and community development. As Chair of Trivallis Housing, he led governance reform, major regeneration programmes, and plans for Penrhys, one of the most deprived communities in the Valleys. He also chaired the all‑Wales group of Housing Association Chairs, contributed to Welsh Government housing policy, and most recently chaired D2, where he led a growth strategy to significantly expand support for people in temporary accommodation.
Jonathan founded Trinity with Amanda to create something different: a model that combines strong housing practice with genuine wrap‑around support, rooted in Welsh values and focused on the people the system most often fails.
Academically, he holds a Doctorate in Leadership from Cranfield, Masters degrees in Behavioural Psychology, European Policy, and Econometrics and Behavioural Economics, and is a qualified public finance accountant (CPFA). He chairs Pwyllgor — Mind in Wales — and sits on the Mind UK board, bringing vital insight into the mental health challenges intertwined with housing instability.
His career — from the Welsh Development Agency to Goldman Sachs, from European policy to coaching council leaders — shapes his view of Trinity as an organisation that must be rigorous, values‑led, and built around the people it serves.
Benjamin Huish
Corporate Executive
Ben Huish is a corporate executive, strategist, and entrepreneur with a background spanning commercial law, corporate finance, and organisational development. He works with leadership teams and organisations to build the strategic, financial, and operational foundations that turn ambition into sustainable results.
Holding a degree in Commercial Law and a Master's in Corporate Finance, Ben combines legal and financial expertise with a hands-on understanding of how organisations actually function. He supports clients across strategy development, financial modelling, digital systems, procurement, and bids — bringing commercial rigour to some of the most complex challenges in the public, community, and housing sectors.
His career has taken him across a range of significant organisations, including Trivallis Housing, Capital People, and Acuity Law, before moving into executive and consultancy roles through Avanti. He currently holds an executive role at Trinity and the Trinity Foundation, focused on homelessness prevention and community support. Alongside this, Ben is completing a programme in Leadership and Entrepreneurship at Harvard, and leads a technology venture focused on transforming how people access and manage services in the consumer market.
Ben operates with a distinctive combination of precision and purpose — as comfortable working through a complex procurement portal or financial model as he is helping a leadership team think clearly about its long-term direction. He brings the perspective of someone who has worked across law, finance, technology, and the third sector, and who understands the connections between them.
Outside of his professional work, Ben holds a world record as the youngest master diver globally, and is a Grade 8 pianist — both of which speak to a character defined by discipline, depth, and the willingness to go further than most.
Our Values
Our values guide every decision we make. They reflect the kind of organisation we choose to be — one that acts with honesty, designs with care, and works alongside others to create real, lasting change. These principles matter because people come to us at moments of uncertainty, and they deserve a service built on trust, dignity and genuine partnership.
INTEGRITY - We act with honesty, transparency and consistency because people deserve to know they can trust us — especially when they are navigating uncertainty. Integrity creates safety, and safety is the foundation for everything else we do.
INNOVATION - We embrace creativity, curiosity and continuous improvement because the current system isn’t working for too many people. Innovation allows us to challenge old patterns, design better solutions and build a housing approach that genuinely helps people move forward.
COLLABORATION - We work alongside councils, partners, communities and the people we support because lasting change only happens when we do it together. Collaboration strengthens outcomes, deepens trust and ensures no one is left to face challenges alone.
PERSON CENTRED - We put the people we support at the heart of every decision because dignity, respect and humanity must guide our work. When we listen deeply and design around real needs, people feel seen, valued and able to rebuild their lives.
ACCOUNTABILITY - We take responsibility for our actions and our impact because the stakes are high — people’s futures depend on the quality of our work. Accountability keeps us grounded, ensures we deliver on our promises and helps us continually improve.
