The Rise of Private Longevity Clinics

In a townhouse just off Grosvenor Square in London’s Mayfair you can have a full body assessment that promises to help you on the journey to live not just longer - “but more importantly healthier and happier”. 

Welcome to Hooke London, one of a flurry of new medical concierge clinics springing up across the world designed to help the worried-well learn more about their bodies. 

With the aim of allowing them to make better informed choices about how to look after themselves, and to provide advice on the best medical professionals to meet their needs.

Access to a central townhouse filled with doctors, nurses, physios and other medical professionals doesn’t come cheap. 

Hooke London membership starts at £14,550-a-year ($19K) which gives clients “unlimited access to an elite team of medical and healthcare experts, expedited referrals and 7-day a week concierge support”. The enhanced Healthspan+ membership, which includes “an annual investigation and nutrition and fitness plan”, sits at £28,500 ($38K). 

The clinic is the brainchild of Lev Mikheev, a Moscow-born theoretical physicist turned hedge fund manager, who became fascinated in “health optimisation” after suffering burnout. 

“He was surprised by how much of a difference it made to his fitness and wellbeing,” his daughter and Hooke London’s chief executive Kate Woolhouse tells us in conversation. “He started running marathons and cross country skiing, doing things he didn’t think he was capable of.”

Like many other very wealthy people Mikheev’s interest quickly turned to “longevity science”. But, he didn’t take it anywhere near Bryan Johnson, the tech entrepreneur spending about $2 million-a-year on a strict scientific diet and exercise "blueprint" regime that he hopes could reverse the aging process and allow him to extend his "don't die" philosophy for as long as possible.

“We’re not here to help people live to 100 or 150 - it’s about allowing them to live well and healthily for as long as possible,” Woolhouse says in one of the plush consulting rooms in the Brooke Street clinic.

“It’s much more about changing attitudes to health - taking a preventative proactive approach, rather than being extremely reactive as most people are.”

The most popular tests are in-depth blood analyses, and if they detect vitamin deficiencies Hooke offers a single tailor-made pill to match each client’s need. The clinic also offers CT and MRI scans which can detect diseases like cancer, heart disease, and organ abnormalities before symptoms appear), and ECGs to detect arrhythmias, heart damage, or structural issues.

Woolhouse had expected that most clients would be on the older side, but was surprised by how many twentysomethings signed up - bringing the average age to the mid 40s. 

“It’s all sorts of people interested in health: Either they have a specific concern,” she says. “Or they worry they’re so busy they could be neglecting their health and want someone to do the work for them.”

Most of the clinic’s members are based in the UK at least part of the year, but there are more European clients than Brits, and a growing number of Americans.

“They are all high net worth people who work hard and travel often,” she says. “Our aim is to fit into their busy people’s lives, and to be a single point of contact through whom they can access all of the healthcare.”

Woolhouse says many clients are referred to Hooke via family offices, which are taking an increasingly proactive approach to managing their families’ health.

“Keeping the entire family well is important for wealth preservation,” she says. “A decline at the top, middle or bottom can have a great impact on the whole family.”

Ahmed El Barkouki, chief executive of Echelon Health, a rival health clinic that operates in London and Dubai, says: “Family offices are built to manage complexity. They oversee wealth, governance, succession planning, investments, risk, compliance, staffing, and security – often across multiple jurisdictions and generations. Yet one of the most significant risks to continuity, performance, and decision-making is frequently left unmanaged - healthcare.”

El Barkouki says family offices that “integrate” health screening into their strategy are able to spot developing issues early, and “protect a family office’s most valuable asset: its people.”

Hannes Hofmann, former head of the global family office group at Citi Private Bank previously noted how family offices are increasingly becoming “responsible for a family’s human capital, especially when it comes to preparing the next generation for succession”. 

“Assisting families with healthcare management is a logical evolution,” he shared in a Citi report titled Navigating healthcare for principals and families. “Logical as it may be, however, healthcare management represents unfamiliar territory for many family office executives.”

He advised that family offices explore three models - and ultimately pick and choose between them. The first is the “donor model” in which families are likely to be able to “receive priority access to leading specialists, treatments, and facilities” at medical institutions to which they have donated philanthropically. 

The second option is the “healthcare advisory model” in which the family members’ medical records are aggregated and stored centrally allowing immediate - secure - access when needed. The providers of this service also employ, or have direct access, to leading specialists and researchers who can provide second opinions on all types of medical conditions and treatments. 

The third option is to sign up to a medical concierge service like Hooke. Similar services are available across the world with, perhaps naturally, a strong contingent in Switzerland - including Clinique La Prairie and SIP Medical Family Office. 

The US, though, is by far the biggest market with an estimated 22,000 medical concierge physicians in the US. 

Among the biggest in the US is Private Medical, which charges $40,000 per adult and claims to serve more than 1,000 wealthy families, with offices in San Francisco, Silicon Valley, Santa Monica and Beverly Hills, New York and Miami. 

Big US hospital groups including Johns Hopkins Medicine, Mount Sinai and the Mayo Clinic now offer concierge packages. MedStar Health, a major system in the Washington, DC, area, recently launched a Signature concierge practice

Overall, the US concierge medicine market was worth an estimated $20.4bn in 2024, according to Renub Research, which expects it to grow to more than $48bn by 2033. 

“The rise in affluent, health-conscious populations, especially in urban areas, has significantly boosted demand for concierge medicine,” Renub said in its 2025 market report. “Busy professionals, executives, and retirees are increasingly willing to pay for premium healthcare that saves time and delivers personalised attention.”

At Hooke in London, Woolhouse says it is the personal relationships that build up over time that matter most to clients. 

“Your health is a real long term relationship, if your medical team knows you really well and knows your history they will keep you healthier,” she says. “We want to build those long term relationships, so we can build resilience in clients, so they can bounce back from whatever knocks they face.”
