We pair a longitudinal, physician-led primary care relationship with the only physiologic testing built to track your healthspan trajectory year over year — not just treat what's wrong today.
Personalized primary care and evidence-based healthspan medicine for adults who want more from their healthcare. Pillar Healthspan combines direct physician access, comprehensive primary care, and proactive healthspan planning to help you stay healthier, stronger, and more resilient for years to come.
Most healthcare is designed to diagnose and treat disease after it develops. Pillar Healthspan was created to do more.
Our membership model allows us to spend more time with patients, provide direct physician access, and focus on the factors that have the greatest influence on long-term health — exercise, nutrition, sleep, and meaningful relationships. We go beyond tracking routine lab work and follow the metrics that help us understand your exercise, nutrition, and sleep habits so you can live better, longer.
Whether you're managing chronic conditions, optimizing your health, or simply looking for a physician who knows you, our goal is to help you navigate your healthcare with clarity and confidence.
Real time to think, plan, and adjust together — not a 12-minute slot.
Message your physician directly — same-day responses, not phone trees.
We track the habits and biomarkers that shape how well you age.
Includes your Healthspan Reserve Index assessment.

Most annual physicals tell you whether you're sick today. The Healthspan Reserve Index (HRI) is built to answer a different question: is your body built to stay well for the next thirty years?
Every Pillar Healthspan member begins here. In a single in-person visit at Core Wellness, Dr. Sadler and our performance team gather the data that the medical literature most consistently links to long-term function and mortality risk — measurements a standard physical never touches:
Then a physician — not an algorithm — interprets all of it together, in the context of your medical history and current medications. You'll leave with your Healthspan Blueprint: a personalized digital book about you, built with Longevity AI and reviewed by your physician, translating your results into a clear picture of where you stand today and what to focus on next.
A single data point is a snapshot. That's why the HRI isn't a one-time event — it's built into your membership. Every year, we retest your strength and cardiorespiratory fitness, update your book, and track your trajectory against your own established baseline. Not just where you are, but where you're headed.
Grip strength, cardiorespiratory fitness, and rate of force development are among the most extensively studied predictors of long-term health outcomes in the medical literature — in many studies, stronger predictors of future risk than cholesterol or blood pressure alone. Most healthcare never measures them. We build our model of care around them.
The HRI is performed in person at Core Wellness in Little Rock — a facility built for performance, with on-site fitness space and in-house lab draws, so your entire assessment happens in one visit, one location. It's the one part of care at Pillar Healthspan that isn't virtual-first. Everything else — your ongoing physician relationship, medication management, and care coordination — continues wherever you are.

Our four pillars represent the core drivers of long-term healthspan: exercise, nutrition, sleep, and meaningful human connection. Pillar Healthspan's entire model of care is organized around improving those core foundations through evidence-based, physician-led medicine.
Comprehensive family medicine with a healthspan overlay — so every visit is also a step toward a longer, stronger life.
Personalized training programs and movement screens — built for everyday performance and longevity.
Whole-food protocols, lab-guided protein targets, and seasonal plans tailored to your goals.
Wearable-informed assessment, evidence-based sleep coaching, and circadian alignment.
Loneliness and stress are clinical risk factors. We build relationship and meaning into every plan.
Comprehensive bloodwork, body composition, VO₂ max testing, and cardiovascular risk profiling.
Everyday primary care done right — acute, chronic, and preventive — for adults and families.
No. Pillar Healthspan is not insurance and doesn't replace it. Your membership covers your relationship with Dr. Sadler — direct access, comprehensive primary care, and preventive planning. You'll still want insurance (or Medicare) in place for hospital care, specialist visits, imaging, medications, and emergencies. Many members pair their Pillar Healthspan membership with a high-deductible health plan for exactly this reason.
For many members, yes. As of January 1, 2026, federal law recognizes qualifying direct primary care memberships as HSA-eligible up to $150/month for an individual — exactly where our membership is priced. Because eligibility depends on your specific health plan, we recommend confirming with your HSA administrator or tax advisor before enrolling, particularly regarding the one-time initiation fee.
Pillar Healthspan membership fees are paid directly and are not billed to Medicare or Medicaid. Many members keep their existing Medicare or Medicaid coverage active for hospital care and specialist referrals alongside their membership.
Always use your insurance and, in an emergency, call 911 or go to the nearest emergency room. Membership doesn't cover hospital or emergency services — it's what happens around them: helping you get to the right specialist, coordinating your care, and making sure nothing falls through the cracks.
The HRI is included in every new member's one-time initiation. Establishing your physiologic baseline — strength, cardiorespiratory fitness, and key biomarkers — is core to how we practice medicine here, not an optional add-on.
Plan for about an hour. The cardiorespiratory and strength testing are submaximal — built to estimate your fitness without requiring you to push to exhaustion — and the lab draw is a standard blood draw. Most members find it closer to a solid workout than a medical procedure.
Dr. Sadler is a board-certified family medicine physician with a background in primary care, medical leadership, and applied microeconomics. He founded Pillar Healthspan to create a more proactive, evidence-based model of medicine focused on helping patients maximize long-term health, resilience, and quality of life.
Throughout his career, Dr. Sadler has cared for diverse patient populations across military medicine, veteran healthcare, and community primary care while also serving in physician leadership roles overseeing clinical operations, quality standards, and physician training. His experience includes work in preventive medicine, sports medicine, operational medicine, and longevity-focused biomarker analysis.
At Pillar Healthspan, his philosophy centers on the belief that the greatest drivers of long-term health are often the most foundational: exercise, nutrition, sleep, and meaningful relationships. Rather than reacting to disease after it develops, he works closely with patients to strengthen physiologic reserve, improve metabolic and cardiovascular health, and preserve long-term function and independence.
His approach combines modern evidence-based medicine with the accessibility, trust, and continuity of a traditional physician–patient relationship — helping patients build a stronger, healthier future over decades, not just years.
