Our Philosophy
“After more than two decades in the ICU, I’ve seen the same story too many times—patients arriving when disease is already advanced and options are limited. Those experiences revealed the patterns, pitfalls, and warning signs that often lead to critical illness.
Today, at Perpetua Longevity, our mission is to identify risk early, intervene sooner, and prevent what we can—optimizing health, delaying chronic disease, detecting heart disease and cancer at earlier stages, and extending both lifespan and healthspan.”
Together, Dr. Juan Chavez and Dr. Lucia Mireles-Chavez bring more than 40 years of combined clinical experience. Dr. Juan Chavez spent years caring for critically ill patients in the Intensive Care Unit, where he witnessed firsthand the devastating consequences of preventable chronic disease.
In their practices, they cared for patients suffering from complications of obesity, diabetes, cardiovascular disease, hypertension, metabolic dysfunction, poor sleep, and other chronic conditions that often develop silently over decades.
We founded Perpetua Longevity with a simple mission: to help patients optimize their health before disease develops, preserve function as they age, and maximize both lifespan and healthspan through evidence-based preventive medicine.
Rather than waiting for illness to occur, we focus on identifying risk factors early, optimizing metabolic health, improving body composition, balancing hormones, enhancing sleep and recovery, and implementing personalized strategies designed to improve long-term outcomes.
Our goal is not simply to help patients live longer. Our goal is to help patients remain stronger, healthier, more energetic, and more independent throughout their lives.
Why Perpetua
Most patients see multiple providers for hormones, weight management, hypertension, diabetes, sleep concerns, nutrition, and preventive care. Perpetua provides a physician-led longevity plan — managed by a husband and wife team — that integrates all of it.
Every plan is authored by one physician who knows your full history.
Intervene decades before disease — not after diagnosis.
Hundreds of data points distilled into a single, legible roadmap.
Direct, secure messaging with your physician between visits.
Treatments grounded in clinical literature, not trend cycles.
Hormones, metabolism, sleep, cognition and performance — integrated.
The Perpetua Method
The seven foundational domains of The Perpetua Method. Every patient receives a plan that integrates all seven — not a menu of treatments, but a unified strategy for healthspan.
Hundreds of data points to map your true biology — far beyond a standard physical.
Reverse insulin resistance, restore body composition, and protect mitochondrial function.
Evaluate and rebalance the endocrine system — for energy, mood, body composition, and sexual health.
Physician-guided cellular therapies grounded in current evidence — never marketed as miracles.
Recovery, repair, and resilience — drawn from sports medicine and regenerative protocols.
Board-certified lipidology applied to stop atherosclerosis decades before a cardiac event.
Protect the brain you'll need at 80 — starting today.

Services
Physician-led precision medicine organized into four focused categories of care — each designed to help you live longer, prevent chronic disease, and perform at your best.
Perpetua Longevity provides concierge virtual longevity care throughout Nevada and California — physician evaluation, personalized planning, prescribing where clinically appropriate, and coordination of advanced testing. In-person consultations, diagnostics, hormone optimization, IV therapy, regenerative medicine, and aesthetic procedures are available by appointment at our Las Vegas office. Specialized imaging and laboratory studies may be performed by qualified independent facilities.

Learn morePhysician-Guided Therapy Evaluation
Alongside the care we deliver virtually and at our Las Vegas office, we evaluate the scientific evidence behind emerging longevity therapies — including Hyperbaric Oxygen Therapy, Red Light Therapy, sauna therapy, cold exposure, and targeted interventions — and advise whether they may be appropriate for your individual goals and medical history.
When a therapy aligns with your personalized longevity plan, we help you identify reputable local providers and integrate it into a comprehensive, evidence-based strategy with ongoing medical oversight.
We evaluate whether IV NAD⁺ or oral precursors (NR, NMN) may be appropriate for your mitochondrial health goals, reviewing the evidence, contraindications, and expected benefits before making a recommendation.
We assess emerging senolytic research and discuss whether investigational compounds may be suitable for carefully selected patients under close medical supervision.
We review your metabolic profile, cardiovascular risk, and longevity goals to determine whether mTOR modulation may be appropriate, with thorough risk–benefit counseling and ongoing monitoring.
We evaluate whether low-dose methylene blue may support your mitochondrial or cognitive health objectives, providing physician-directed guidance on safe use and monitoring.
We review the evidence for HBOT in tissue repair, cognitive recovery, and inflammation reduction, advise when it may align with your goals, and help identify reputable local providers when appropriate.
We assess whether photobiomodulation may benefit your skin, musculoskeletal, mitochondrial, or cognitive health goals, and guide you on selecting reputable local treatment options when indicated.
We evaluate the evidence for deliberate heat and cold stress protocols in cardiovascular, metabolic, and cognitive health, and help you integrate safe, personalized protocols into your plan.
We assess whether targeted peptide protocols may support recovery, immune signaling, or tissue repair goals, and when clinically appropriate, provide physician-directed recommendations with ongoing oversight.
We design personalized light, meal-timing, temperature, and sleep-architecture strategies grounded in your chronobiology and metabolic profile to slow biological aging.
We prescribe Zone 2 aerobic training, VO₂ Max intervals, and resistance protocols tailored to your physiology — the single most evidence-backed longevity intervention available.
Several therapies in this list remain under active investigation. Perpetua Longevity physicians discuss the current state of the evidence, expected benefits, risks, and unknowns before any recommendation is made. Nothing on this page is a guarantee of clinical outcome. Our role is to provide expert evaluation, personalized guidance, and ongoing oversight. Treatments we do offer — including hormone optimization, IV therapy, regenerative and aesthetic procedures — are performed in person at our Las Vegas office.

Patient Experiences
At 62 years old, I've learned how to reverse much of the aging process. My VO₂ max, strength, and body composition continue to improve, and I feel better than I have in years.
After struggling with injury, declining health, and excess weight, Dr. Chavez helped me completely transform my life. Today I enjoy excellent health and remain highly active.
For more than a decade, personalized care under Dr. Chavez's guidance has been a cornerstone of my health journey.
Dr. Chavez took the time to thoroughly evaluate my health and create a clear roadmap for achieving optimal results.

Founding Physicians
Dr. Juan Chavez and Dr. Lucia Mireles-Chavez lead Perpetua Longevity with more than 40 years of combined clinical experience. Their work spans Internal Medicine, Pediatrics, Obesity Medicine, Anti-Aging and Regenerative Medicine, Hyperbaric Medicine, Hormone Optimization, and Aesthetic & Sexual Wellness.
Dr. Juan Chavez's two decades caring for critically ill patients in the Intensive Care Unit inspired a proactive philosophy: prevent disease before it occurs, restore vitality, and help patients maximize both lifespan and healthspan.
Dr. Juan Chavez is also a board-certified Clinical Lipidologist (American Board of Clinical Lipidology) — one of a small group of physicians nationally credentialed to diagnose and treat atherosclerotic cardiovascular disease at its root. This allows him to aggressively manage cholesterol, lipoprotein(a), ApoB, and inflammatory drivers of arterial plaque to help prevent heart attacks, strokes, and premature cardiovascular death long before symptoms appear.
Both physicians are members of the American Society of Ketamine Physicians (ASKP3) and have personally administered hundreds of supervised IV ketamine treatments for patients with treatment-resistant depression, chronic pain, and substance use disorders in prior clinical practice. Today, we evaluate candidacy and coordinate care with qualified ketamine providers.
