Who we are
We’re a team of patients, doctors, and engineers working together to build a better way to recover from complex illness.
Built by people who get it.
Paddy Monahan - Founder
"I’ve lived with long COVID since 2020. Like many of you, I’ve spent years trying to make sense of conflicting advice, experimenting with treatments, and searching for what actually helps. Circular Health is the tool I wish I had to help guide recovery."
Dr. David Kaufman M.D. - Clinical Lead
Dr. David Kaufman is one of the world’s leading experts in complex chronic illnesses, with over two decades of experience treating conditions like ME/CFS, long COVID, POTS, MCAS and other complex illnesses.
Barry Rafferty-Lynam - Head of Engineering
Barry is a health tech veteran with 10+ years of experience building secure healthcare systems. After going through a multi-year recovery from an acquired brain injury, he’s deeply committed to creating tools that truly support complex healing.
How it all started
There are effective treatments out there — but finding them is too slow, too fragmented, and too exhausting.
I’ve lived with long COVID since 2020. Like so many others, I spent years navigating conflicting advice, trying treatment after treatment, and searching for answers with limited support. What I found was that some things really do help — but most patients discover them by chance, not because the system makes it easy.
That’s why we started Circular Health.
We’re building a platform that helps surface what’s actually working — faster. By combining emerging research, expert clinical guidance, and real patient outcomes, we make it easier to understand which treatments are safe, promising, and worth considering.
To make sure what we build is both rigorous and genuinely useful, we’ve teamed up with Dr. David Kaufman — a world-leading expert in ME/CFS, long COVID, and related conditions — and a team of engineers and designers focused on making complex recovery simpler.
Circular Health exists because we’ve lived the problem — and we’re building the solution we wish had existed when we needed it most.
