A Better Way to Experience Healthcare

Most healthcare treats disease. We were built to do more.

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.

Healthspan Reserve Index

Measure what actually predicts how long, and how well, you'll live.

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:

Cardiorespiratory fitness, estimated via the YMCA submaximal cycle protocol, a validated, evidence-based method for estimating VO₂ max without maximal exertion
Muscular strength and rate of force development, measured with clinical-grade force testing
Balance, mobility, and functional movement capacity
Comprehensive laboratory analysis covering cardiovascular, metabolic, and inflammatory biomarkers, drawn on-site
Body composition

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.

Because a single data point is only a snapshot, the HRI is built into your membership rather than treated as a one-time event. Every year, we retest your strength and cardiorespiratory fitness, update your book, and track your trajectory against your own established baseline, so you can see not just where you are but where you're headed.

Why It Matters

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, and in many studies they predict future risk more strongly than cholesterol or blood pressure alone. Most healthcare never measures them, which is why we build our model of care around them.

Where It Happens

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 a single visit at one location. It's the one part of care at Pillar Healthspan that isn't virtual-first. Everything else, including your ongoing physician relationship, medication management, and care coordination, continues wherever you are.

The HRI is included with membership. See Membership for full pricing.

Frequently Asked Questions

The questions people ask first.

Does membership replace my health insurance?

No, Pillar Healthspan is not insurance and doesn't replace it. Your membership covers your relationship with Dr. Sadler, including 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.

Can I use my HSA to pay for membership?

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, which is 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.

Do you accept Medicare or Medicaid?

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.

What if I need to see a specialist, go to the hospital, or need emergency care?

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 themselves; it covers what happens around them, such as helping you get to the right specialist, coordinating your care, and making sure nothing falls through the cracks.

Is the Healthspan Reserve Index required, or can I join for primary care alone?

The HRI is included in every new member's one-time initiation. Establishing your physiologic baseline of strength, cardiorespiratory fitness, and key biomarkers is core to how we practice medicine here, not an optional add-on.

How long does the Healthspan Reserve Index take, and is any of it uncomfortable?

Plan for about an hour. The cardiorespiratory and strength testing are submaximal, designed 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.

Meet Your Physician

Dr. Corey Sadler, DO, MS

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 rather than just years.
