Interim Chief Executive

Sian’s career with The Wallich began in 2008 with the Rough Sleepers Intervention Team in Bridgend. There, she championed service user involvement and volunteering.

Sian’s background was not initially in the third sector but has a unique perspective. For eight years, she worked for a solicitor with a Business Management degree. After having children, Sian made a conscious decision to leave her job in the corporate sector and put her skills to use helping people instead. We’re glad to say, she’s never looked back.

In October 2013, Sian managed The Wallich’s service user volunteer programme across Wales (RSVP). Her role continued to expand into co-production and creating opportunities for clients, including developing innovative ways to engage and involve our service users.

Sian became Head of our first Participation and Progression team (now called Service Innovation and Enhancement). There she oversaw all projects related to skills, employability and wellbeing. She is passionate about helping people to engage in their communities through heritage, arts, culture and sport.

Sian was appointed as Deputy Director of Operations in 2019, where she continued to lead on creative and innovative service delivery across all of our services in Wales. A year later, she became the full Director of Operations, overseeing all charity operations across Wales.

Over her 18 years at The Wallich, Sian has been pinnacle in driving The Wallich’s journey into becoming a trauma-informed organisation and PIE. She’s also led the charge on our work relating to harm reduction, health inclusion and our large mobile outreach vehicles.

She’s undertaken the role of Interim CEO for two periods of time and now, in 2026, steps into the role permanently.

Outside of The Wallich, Sian is a proud member of Cymorth Cymru’s Board of Trustees. She works alongside other passionate and experienced individuals from the sector to help govern the important influencing work undertaken by the team at Cymorth.

“When I set out on my first ‘breakfast run’ in Bridgend years ago and I met my first clients, as I offered a coffee and a friendly ear, I made a commitment to do everything in my ability to facilitate a better life for those experiencing homelessness.

“I would not accept that we live in a society where our people are voiceless, forced to live without the security and warmth of a home. The drive and motivation that was born that day has stayed with me through every role I have undertaken. It’s become my compass, directing me in my work and ensuring that our clients, and the community across The Wallich supporting them, are at the heart of all we do.

“I promise to champion your work on the frontline and lead The Wallich into becoming what we deserve – THE voice of homelessness in Wales. We’ll do this as guided by our new strategy to improve quality, impact and sustainability at The Wallich, and we’ll do it all – together.”
