If you have been comparing a concierge doctor to a longevity clinic, you are not alone. At Lifetime Performance Medicine in Los Gatos, people often arrive assuming the two are the same thing. They are not. Both charge a membership fee, and both promise more attention than a rushed insurance visit, but they are built to do different jobs. We are the longevity division of Lifetime Surgical, and we serve Los Gatos, Saratoga, Campbell, San Jose, and the wider South Bay. Here is an honest breakdown of how concierge medicine and a longevity membership differ, who each one fits, and what the pricing really looks like.
Concierge medicine is, at its core, better access to primary care. You pay an annual retainer to a primary care physician who limits their panel to fewer patients. In return you get longer appointments, same-day or next-day scheduling, direct phone or text access, and a doctor who is not stretched across thousands of patients.
That is a real benefit. If you value being able to reach your primary care doctor quickly, get your annual physical without a long wait, and have someone coordinate referrals and manage ongoing conditions, concierge medicine delivers that. It is primary care with the friction removed.
What concierge medicine is generally not built for is deep, proactive optimization of how you age and perform. Most concierge practices still work within the standard primary care toolkit: a routine physical, standard labs, and treatment when something is wrong. The model improves your access to that care. It does not usually change the depth of the testing or reorient everything around long-term performance.
A longevity membership starts from a different question. Instead of "how do we keep you well and treat problems as they arise," it asks "how is your body aging and performing, and what can we do over the next year to improve it."
That makes it diagnostics-led. At Lifetime Performance Medicine, membership is built around measurement. Members receive a Lifetime Body Score across six domains, a biological age estimate calculated with PhenoAge, and a panel of more than 80 biomarkers. We add a calculated VO2 max, body composition analysis, functional testing, and wearable data, with full DEXA scanning and direct VO2 max testing in the Optimization and Executive tiers. All of it feeds a physician-built 12-month plan that we revisit and adjust through the year.
The output is not just a clean bill of health. It is a score, a set of targets, and a plan. Members work with Morgan Carmean, ARNP, who leads our wellness clinic, and see Dr. Richard Nguyen, DO, our founder and a board-certified surgeon with more than twenty years of experience in the Bay Area, at two visits per year. People across Saratoga, Campbell, and San Jose choose this model because they want direction, not just access.
Here is the cleanest way to hold the distinction.
Concierge medicine sells you access. The doctor is the same kind of doctor you would see in standard primary care, but easier to reach and less rushed.
A longevity membership sells you a direction. The point is not faster access to routine care. The point is a detailed baseline of how you are aging, measured with tests most primary care never orders, turned into a plan you work through over time.
One is about convenience and continuity of primary care. The other is about diagnostics and optimization. Neither is better in the abstract. They fit different people.
You want a primary care doctor you can reach quickly, you value longer and unhurried visits, you have conditions you want managed closely, and your main frustration is access rather than depth. If your goal is a reliable, responsive primary care relationship, concierge is a sound choice.
You feel generally healthy but want to know what is happening beneath the surface, you care about fitness, body composition, and how you age, and you want a plan built on real data rather than reassurance. If you have ever had a normal physical and still felt you were missing the full picture, the longevity model is likely closer to what you are after.
Some people want both, and that is fine. A concierge doctor and a longevity membership can coexist. They cover different ground.
We think pricing should be plain. Concierge memberships in the Bay Area vary widely depending on the practice and what is included, and the retainer typically buys access rather than a defined testing program. Because it varies, ask any concierge practice exactly what the fee covers and what still bills through insurance.
At Lifetime Performance Medicine, membership begins with our Foundations tier from $4,500 per year, with Optimization and Executive tiers available for those who want deeper testing and support. That fee is tied to a specific program: the Body Score, the panel, the scans, and the 12-month plan. We also offer a la carte testing for people who want to start smaller. What you are paying for is the diagnostics and the plan, and we are happy to walk through exactly what each tier includes before you decide.
Yes. Lifetime Performance Medicine is in Los Gatos and serves Saratoga, Campbell, San Jose, and the wider South Bay and Silicon Valley area.
No. We focus on diagnostics-led longevity and optimization. Many members keep their primary care doctor for routine and acute care and use us for the deeper picture and the plan.
Yes. They serve different purposes and work well alongside each other.
Membership starts with Foundations from $4,500 per year, with Optimization and Executive tiers custom to your needs, plus a la carte options. We will explain what each tier includes before you commit.
Every membership begins with the same baseline panel and the same two visits: an intake with Morgan, then your Body Score reveal with me. If you have been guessing about your health for years, the first step is to stop guessing.
Dr. Nguyen has practiced in Los Gatos since 2007. He leads every membership: the Body Score reveal, the 90-day plan, and the annual review.
