About us
A small charity, run by people who have done the science
Duet Health Foundation is a registered charity in England and Wales (no. 1217999). We fund the health research, communication and education that commercial sponsors and government grants pass by.
How Duet started
Mike and Julie Matthews ran a drug development company for twenty-five years. Moving on, they founded Duet to enable them to put to charitable use the knowledge and experience gained from running their international drug development support company.

How we work
Useful before impressive
We would rather fund a small project that changes something than a large one that reads well.
Plain language, always
If we cannot explain a project in everyday English, we do not understand it well enough yet.
Quick and honest answers
We reply to every enquiry, and we say no clearly rather than leaving people waiting.
Credit where it belongs
The researchers and clinicians do the work. Our job is to make it possible.
Governance and money
01
Who decides
A Board of Trustees, chaired by Julie Matthews, meets quarterly. Every grant is approved by the Board, with medical assessments led by Mike Matthews.
02
Where donations go
Our Founders meet Duet's core running costs, so money donated is spent on charitable activity rather than overheads.
03
What we publish
Annual accounts and the Trustees' report are filed with the Charity Commission under number 1217999. Where our work produces scientific results, we aim to publish them with our collaborators in peer-reviewed journals.
How to get involved
Duet is small enough that one person's help makes a tangible difference. Here are the four things people most often do.

Small charity, practical help
