How it works
STEP 1
Membership starts with your baseline
This isn't a typical annual checkup. It's a complete starting point that gives your health context so your next decisions are clear.
A premium baseline experience
A start that feels nothing like traditional healthcare: coordinated, calm, and efficient.
Multi-domain assessment
We look across the pillars that actually shape healthspan: sleep and recovery, metabolic health, fitness capacity, stress load, and prevention.
Your first plan, fast
Leave your baseline with clear next steps. No waiting weeks to know what matters.
STEP 2
Your results are analyzed and explained
Your WithThem clinical team translates your baseline into a practical map: priorities, tradeoffs, and a plan you can live with.
Clinician-guided review
Meet with a clinician to review your results, discuss priorities, and align on a plan that fits your goals and constraints.
A simple risk map
Your results are synthesized into a clear profile: what to address now, what to monitor, and what to ignore.
When something needs attention, we coordinate
If follow-ups are needed, we help you move quickly and clearly so nothing important gets lost in the shuffle.
STEP 3
Expert guidance to turn insights into better health
The difference isn't what you learn; it's what actually changes. WithThem keeps your plan alive, current, and doable.
Ongoing measurement, at the right cadence
Follow-up testing and check-ins when it matters: enough to stay on top of things, not so much that it takes over your life.
Daily guidance across domains
Sleep, training, nutrition, stress, and prevention: your plan is coordinated across the whole system, not optimized in silos.
A plan for what's next
Regular reviews to refine your protocol, adjust for real life, and keep progress compounding quietly over time.
STEP 4
Your plan adapts when life changes
Longevity isn't static. Your training shifts. Your supplements change. You travel. You start a new medication. WithThem helps you understand what's changing and what it means so progress stays steady.
A personal concierge team for change
Starting GLP-1. Changing protein or creatine. New trainer. New sleep routine. We help you integrate changes into your plan without guesswork.
Measure impact, not vibes
We track what matters and adjust your cadence when needed so you can see whether a change is helping, neutral, or pulling you off course.
Guardrails, not chaos
With clinical guidance and a structured approach, you can iterate safely and keep your plan grounded in your actual biology.
