How Reborne Longevity is quietly redefining what executive healthcare looks like, from a Georgian townhouse in Marylebone

Sponosored content

Most senior executives in Mayfair already have a private GP, comprehensive insurance and an annual check-up in the diary. What they rarely have is the deeper diagnostic picture – the bloodwork, hormone profiling and cognitive markers that actually shape how they sleep, focus and perform across a long working day. It is the difference between functioning well and functioning at one's absolute best.

Set within a discreet Georgian townhouse in Marylebone, Reborne Longevity is a private health and longevity CQC registered hospital working with senior executives and their families on the clinical detail that standard healthcare rarely covers. Hormone health, metabolic and cardiovascular markers, risk profiling, sleep and cognitive performance, and the preventative work that builds long-term resilience. Wearable data is integrated into assessments, so the clinical picture reflects how a client actually lives, sleeps and recovers day to day.

“A standard health check tells you whether something is wrong today. The work we do is about understanding what shapes performance tomorrow, and what protects health over the next 20 years,” explains the team at Reborne. “Sharper cognition, deeper sleep, sustained energy through long days – these are clinical outcomes, and they are measurable.” 

Central to the offering is the Executive Longevity Assessment, a personalised consultation tailored to the individual. For male clients, this is led by the clinic's Male Longevity Expert and covers cortisol, cardiovascular markers, testosterone, peptide education and recommended testing across bloods, bone density and liver health. For female clients, the clinic's Female Longevity Expert leads on energy, cortisol, hormone balance, perimenopause and menopause markers, and metabolic and cardiovascular health. Every plan is built around the individual.

Social Events at Reborne

Beyond clinical work, Reborne partners with select private members' clubs and family offices across London to host curated wellness experiences, and its members' lounge offers a refined alternative to the usual client entertaining format – private group sessions, IV therapy evenings and curated “Reborne Reset” gatherings that bring people together in a more considered way.

Reborne is now extending a Private Member Preview to a curated group of senior executives this quarter, by referral only and limited to the first 20 introductions. The Executive Longevity Assessment is offered at £400 for this group, against the standard £600.

For the personal assistants who keep Mayfair running, it is a way to put something genuinely useful in front of a boss – the kind of clinical detail that a private GP rarely has the time or scope to deliver.
