Marcus Lewis founded Sanctuary Media Group in 2016, after 20 years working in direct response media, and partnering with charities to drive measurable campaign success through data-led media strategy.

That experience gave him a clear vision: to build an agency defined by its values, not just its client list. Marcus set out to create a media partner built specifically for the charity sector - one where sharp strategic thinking, rigorous performance, and genuine partnership aren't reserved for the biggest accounts, but are simply how Sanctuary operates, for every client, every time.

That's the ethos Sanctuary Media Group was built on. We work exclusively with organisations doing important work - driving real, measurable change - and we bring them the same calibre of thinking, rigour, and attention that any commercial brand would expect from a leading agency.

We believe the causes our clients fight for deserve nothing less.
