About us

DHA are policy, research and communication specialists. We help communities, charities, networks and public sector agencies across the UK, and beyond, to understand and influence the world around them.

We work at all levels – from grassroots community projects to government agency initiatives – to deliver communications, advocacy and research expertise which helps shape real change, make sense of complexity and bring people closer to the decisions that affect their lives.

We specialise in arts and culture, global development and social change and sustainability, working across design, storytelling and strategy development through to policy advocacy, discourse analysis, evaluation and learning.

"Your flair and your close attention to detail made it a pleasure to work with you."

Storytelling lies at the heart of what we do and the way in which we help people shape the world around them. We use our writing and design skills to develop powerful narratives which combine clarity and coherence with compelling content to inspire understanding and action across different platforms.
