✦ About

The practice, and the people in it.

Why we built it.

Dr Ranulf CrookeDr Andrew CrockettYoni GottliebJeff HaggardDr Jaye NoelSabrina Percy

Ran and Andy have worked together since their time rowing together. Their subsequent careers, spanning elite sports and military medicine, created the basis for building this practice from the same principles of these disciplines.

They came together to solve a problem of siloed and fractured information in healthcare, failure of the full integration of performance medicine alongside conventional medicine and clinics selling well ahead of the evidence base. That is why this practice is independent and diagnostically agnostic: free to use whatever the research actually supports, and free to say when nothing is worth doing.

They were joined on this journey by Yoni, to build out the operations that an international concierge depends on; Jeff, as the clinic expanded to the US, bringing his keen attention to the member experience; Jaye, as our Chief Medical Officer in the US and our expert on hormonal health; and Sabrina, frustrated by the lack of continuum between psychological and biological approaches to long-term healthcare and set on building the optimal environment for individuals to realise their fullest potential. Together, they want to grow a community of like-minded members and practitioners, to lead by example and join members on their journey through Experiential Medicine.

The science of flourishing.

Most of medicine is reactive and focuses on responding when people present with symptoms when they are ill.

Salutogenesis studies the opposite: what actually allows a body to do well, and, just as we do with elite athletes, what we can focus on in a defined block of time to elevate people to their fullest potential.

We start with a Deep Dive into how your body is actually working today, and build from there. Every assessment and every decision is tailored to the person in front of us rather than a package from a protocol.

Our clinicians come from a diverse background of senior NHS clinicians, research, elite sports and military medicine. They have looked after founders under load, executives at altitude, paratroopers in the field, and people driven by a sense of purpose, along with their families.
