Top 25 Doctors, Clinics and Longevity Centers in the World

Longevity is no longer a niche conversation among biohackers, labs, and high-net-worth patients. By 2026, the concept has shifted to much more serious ground: advanced preventive medicine, biological age assessment, early detection, geroscience, metabolic health, cognitive health, and maintaining functionality over more years. The central idea is no longer just living longer, but expanding healthspan — that is, the years lived in good health, with autonomy and physical and mental performance. Stanford, Johns Hopkins, Columbia, Mayo, NUHS, and the Max Planck Institute, among others, insist precisely on this direction: invest earlier, measure better, and translate research into clinical practice and public health.

This ranking should not be read as a list of “the most famous,” but rather as an editorial classification built on five variables: real clinical capacity, scientific foundation, integration of disciplines, focus on prevention and functional health, and international reach. In other words, it is not enough to sell expensive check-ups or wellness retreats. To be included here, one must demonstrate, to varying degrees, a combination of medicine, diagnosis, research, personalization, and long-term vision. In some cases, we are talking about academic hospitals and university centers; in others, about private precision clinics that have turned longevity into a premium healthcare category.

FIFTIERS Editorial Methodology

To build this ranking, priority was given to the presence of one or more of these elements: medical or clinical programs focused on healthy aging; active research in the biology of aging or geroscience; use of biomarkers, AI, genomics, or precision medicine; a comprehensive approach to brain, metabolism, mobility, sleep, and prevention; and a proven ability to influence the global debate on longevity. That is why hospitals, university institutes, and private clinics coexist in the ranking. They do not all do the same thing, but they all participate in building the new global map of longevity.

1. Sheba Longevity Center — Israel

Sheba takes first place for a clear reason: it has succeeded in combining an academic hospital, personalization, AI, and longevity medicine into a single structure. Its own institutional positioning presents it as the first academic longevity center that combines artificial intelligence, personalized medicine, and cutting-edge research to optimize biological age and healthy aging. Furthermore, Sheba Medical Center operates on a large scale, with 159 departments and clinics and over one million patients per year, giving it a depth of care that few private brands can match.

2. Mayo Clinic / Healthy Longevity Clinic & Kogod Center on Aging — United States

Mayo Clinic sits in the elite due to its ability to connect aging research, clinical practice, and global medical reputation. The Robert and Arlene Kogod Center on Aging defines aging as the greatest risk factor for most chronic diseases, and Mayo now even communicates a “Healthy Longevity Clinic” with specific medical leadership. Its competitive advantage is hospital robustness, medical credibility, and the ability to take longevity from scientific discourse to the real clinical circuit.

3. Stanford Medicine Center for Longevity and Healthy Aging — United States

Stanford is a global reference because it approaches longevity from a broader angle than the luxury medical check-up. Its center is funded by the NIH, led by VJ Periyakoil, and combines AI, big data, wearables, virtual reality, and precision medicine to transform the aging experience. Stanford does not just research longevity: it helps redefine the very intellectual framework of the sector.

4. Stanford Center on Longevity — United States

Although its profile is less clinical and more strategic, the Stanford Center on Longevity deserves to be in the Top 5 because it has been one of the main architects of the contemporary language of the longevity economy. Its stated mission is to accelerate scientific discoveries, technological advances, habits, and new social norms so that hundred-year lives are healthy and fulfilling. Its report The New Map of Life has been one of the most influential texts in the transition from “aging” to “living long with purpose.”

5. Centre for Healthy Longevity, NUHS / Alexandra Hospital / NUS — Singapore

Singapore has moved very quickly toward institutionalizing longevity as a health policy and innovation platform. The Centre for Healthy Longevity states its mission as adding healthy years of life by delaying aging, prolonging disease-free life, and maintaining high functionality. Its connection to the university system, Alexandra Hospital, and translational research makes it one of the most interesting projects in Asia.

6. Buck Institute for Research on Aging — United States

The Buck Institute is not a typical clinic, but it is impossible to talk about global longevity without including it. It presents itself as the world’s first independent biomedical institute focused exclusively on aging, with the mission to end the threat of age-related diseases. Its scientific weight and role in fundamental research make it a central piece of the global ecosystem.

7. Johns Hopkins Center on Aging and Health — United States

Johns Hopkins maintains a reference position due to its multidisciplinary approach and having consolidated a center of excellence in aging research since the late 1990s. It brings together more than 40 faculty and researchers from Medicine, Public Health, and Nursing, focusing on health, longevity, and well-being. It is an especially strong institution when the debate shifts from commercial promises to epidemiology, policy, and evidence-based medicine.

8. Robert N. Butler Columbia Aging Center — United States

Columbia has been one of the institutions that has best worked on the idea of “increasing healthspan for all” and making longevity a social asset. The Butler Columbia Aging Center is less of a “premium clinic” and more of a powerhouse for high-impact thought, research, and education. For a serious ranking, that intellectual dimension matters greatly, because part of the future of longevity is decided at the intersection of public health, inequality, behavior, and aging.

9. Max Planck Institute for Biology of Ageing — Germany

Another non-clinical but essential player. The Max Planck Institute for Biology of Ageing defines itself as one of the world’s leading institutes dedicated to understanding the natural process of aging and how to intervene to mitigate or prevent age-related diseases. When an institution of this caliber publishes findings on drug combinations or biological mechanisms of aging, it directly influences the next generation of longevity medicine.

10. UZH Healthy Longevity Center — Switzerland

The University of Zurich has successfully built a center that articulates research, innovation, and social impact around healthy longevity. Its approach emphasizes measuring, understanding, and improving functionality throughout life — a key variable for distinguishing true longevity from mere survival extension.

11. Northwell Institute for Healthy Aging / Age Friendly Center of Excellence — United States

Northwell stands out for bringing the concept of age-friendly medicine into clinical practice. In 2024, it opened an Age Friendly Center of Excellence in Oyster Bay and maintains a broad structure of geriatrics and palliative care, in addition to receiving support for age-friendly hospital programs. Its strength lies in scalability and operationalizing older-adult-oriented medicine within a large health network.

12. Cleveland Clinic Center for Geriatric Medicine — United States

Cleveland Clinic does not market itself as a “longevity clinic” in the premium sense, but its research base and clinical power make it one of the big names in healthy aging. Its Center for Geriatric Medicine provides coordinated primary care to help patients stay healthy and active as they age, and the institution has recently highlighted research lines in brain health, diet, frailty, and prediction of age-related conditions.

13. Clinique La Prairie — Switzerland

If there is one iconic brand in luxury longevity, it is Clinique La Prairie. Founded in 1931, it continues to position itself as one of the world’s most recognized longevity clinics and has expanded its presence through Longevity Hubs in cities like Doha, Dubai, and Madrid, with openings underway in other markets. Its authority comes from brand heritage, historical continuity, and the ability to have turned longevity into an international premium category.

14. Lanserhof — Germany / Austria / United Kingdom

Lanserhof is one of Europe’s leading references in preventive medicine, regeneration, and optimization. Its offering combines advanced medical science with holistic approaches and therapeutic fasting programs, and the brand insists that its concept has evolved over decades of practice. Beyond the marketing, its longevity and expansion make it one of the strongest names in the segment.

15. SHA Wellness / SHA Spain — Spain

SHA has consolidated a very strong position in the international conversation on longevity and medical wellness. Its medical team is presented as a group of experts in longevity, preventive medicine, and performance, and its Spanish headquarters emphasizes the integration of diagnostics, precision medicine, and evidence-based therapies. SHA perfectly represents the evolution of premium wellness toward a more medical, less purely hotel-based category.

16. Fountain Life — United States

Fountain Life has scaled rapidly in the segment of longevity aimed at executives and premium members. The firm claims to combine advanced diagnostics and AI based on over 15 billion data points, and in 2025 announced new openings, including Houston. It is one of the brands that best embodies “longevity as executive infrastructure” — that is, longevity as a continuous service for top executives.

17. RoseBar Longevity Clinic at Six Senses Ibiza — Spain

RoseBar has achieved something difficult: inserting a longevity clinic into the ultra-high-end hospitality circuit without losing medical narrative. Its offering speaks of extensive testing, personalized plans, and activation of “longevity pathways,” making it one of the European projects with the most visibility within experience-driven luxury linked to health.

18. Long Life Clinic Marbella — Spain

Long Life Clinic has reinforced its offering by positioning itself as a pioneer since 1991, based on over 100 biomarkers, genetic analysis, and biological age assessment. Its narrative is clearly one of longevity and anti-aging medicine based on continuous measurement and personalized adjustments. Within Spain, it is one of the longest-standing names in this field.

19. LongevityClinics — United Kingdom / International network

LongevityClinics has gained notoriety for its focus on biomarkers, HumanTelemetry, and quantification of biological age, including the use of GlycanAge and wearable tracking. Its offering sits at the frontier between personalized medicine, continuous monitoring, and high-level clinical coaching.

20. Precision Longevity — Canada

Precision Longevity represents a very interesting version of the Canadian clinical longevity model: less spectacular in marketing, but very focused on translating precision medicine into work with real patients. Its founders combine hospital experience, university teaching, and highly credible clinical specialties.

21. Longevity Medical Clinic — Canada

With over 27 years of operation according to its own information, this Canadian clinic presents itself as one of the most experienced in the country. Its longevity and longitudinal approach with patients give it value in an industry where many brands are still young.

22. Longevity Medical Institute — Mexico

Longevity Medical Institute, in Los Cabos, has built an offering that mixes regenerative medicine, advanced diagnostics, and a structure licensed and certified at the Mexican regulatory level. Its emphasis on internal clinical studies and publications gives it an additional layer of credibility compared to many purely commercial clinics.

23. Healthi Life Longevity Clinic — Thailand

Bangkok is consolidating itself as a relevant destination for regenerative medicine and longevity. Healthi Life presents itself as a physician-led clinic, with patients from over 50 countries and a focus on biological age optimization. Asia is growing rapidly in this segment, and this center is a clear example of that expansion.

24. Women’s Wellness & Healthy Aging Program, Johns Hopkins — United States

Although it is a more specific program, it deserves to be included for a fundamental reason: the future of longevity cannot continue to be designed with male or neutral parameters. Johns Hopkins has developed a program dedicated to women’s health before, during, and after menopause, integrating healthy aging practices into a critical stage of the life cycle. It is a clinical line with enormous potential and a direction that will grow significantly in the coming years.

25. Human Longevity / Health Nucleus legacy model — United States

Although its public presence is less dominant today than in its early years, Human Longevity was one of the great catalysts of the idea of combining genomics, advanced imaging, and predictive medicine into a high-level service to extend healthy life. Its historical importance within the sector justifies its entry at number 25, more for its influence on the model than for its current visibility.

What this ranking reveals

The first conclusion is that global leadership in longevity no longer belongs to a single geography. The United States continues to dominate in scientific and hospital capacity, with Stanford, Mayo, Johns Hopkins, Columbia, Buck, Northwell, and Cleveland Clinic. But Israel has made a very powerful leap with Sheba, Singapore is positioning itself with enormous institutional intelligence, and Europe retains significant weight in the premium segment with Switzerland, Germany, Austria, and Spain.

The second conclusion is deeper: a bifurcation of the market is taking place. On one hand, there are academic and hospital centers working on geroscience, epidemiology, functionality, and healthy aging from robust scientific bases. On the other, private clinics are emerging that turn that conversation into premium services, memberships, advanced screening programs, and personalized protocols. The two layers do not necessarily compete — in many cases, they feed each other.

The third conclusion is that longevity is ceasing to be a subcategory of wellness. Today, the conversation revolves around four major pillars: biological age, metabolic health, cognitive health, and early risk detection. The best-positioned players are those that connect these four pieces with longitudinal follow-up and multidisciplinary medical teams. That explains why Sheba, Stanford, Mayo, and NUHS rank so high, and also why brands like Clinique La Prairie, Lanserhof, SHA, and Fountain Life continue to gain ground among executives, family offices, and premium consumers.

Looking to the future

In the coming years, we will see three movements. The first will be the expansion of longevity as executive infrastructure, integrated into health programs for senior executives, business leaders, and investors. The second will be the consolidation of women’s longevity medicine, especially around menopause, hormonal health, bone health, sleep, and cognition. The third will be the entry of more clinical AI, composite biomarkers, and predictive models to transform a one-time check-up into a continuous monitoring system.
