How PNOĒ works
The breath analysis on PNOE measures the concentration of oxygen, carbon dioxide, and flow volume during inhalation and exhalation.
The PNOE metabolic assessment gives detailed information about the heart, lungs, muscle health, high-level cardiovascular function, and overall metabolism in our body.
PNOE is considered the highest level of testing system for physical fitness and health assessments, and physiology.

Why I Built AT Longevity & Performance
AT Longevity & Performance exists to fill a gap I saw repeatedly: capable, motivated people who want to age well but don’t want extremes, guesswork, or conflicting advice. It is a personalized, prevention-focused longevity practice designed to help people understand how their body responds to everyday life, stress, sleep, movement, recovery, and aging, and then make thoughtful decisions before problems become diagnoses. I chose to step upstream, where small, intentional changes can still have a meaningful impact.My Perspective
Most wellness programs focus on doing more. More workouts. More supplements. More protocols. My approach is different. I focus on sequencing, doing the right things in the right order. We start by stabilizing daily rhythms and recovery, because without those foundations, nothing else sticks. From there, we layer in precision only when it adds real value.A Personal Note
I built the AT Longevity & Performance using the same principles I follow in my own life. This work reflects both my professional training and my personal commitment to aging with strength, clarity, and intention, without fear or noise. I keep this practice small because trust matters here. Judgment matters. And longevity is not something to rush. *Longevity isn’t built by doing everything at once. It’s built by understanding what matters most and honoring it consistently.Discover why metabolic analysis is relevant for all fitness and health goals

ΑΤ LONGEVITY & PERFORMANCE
Precision Longevity. Built From Your Physiology.
Longevity is not generic.
Your metabolism, recovery capacity, and training response are uniquely yours.
AT Longevity & Performance uses advanced metabolic and VO₂ max testing to build a fully individualized strategy for nutrition, training, recovery, and long-term performance — grounded in your actual physiology, not averages.
Active Metabolic Rate (AMR) Test
- Measures VO2 Max and how your body responds to exercise.
- 30 minute initial consult
- A 15–20 minute exercise test, usually on a treadmill or bike, with intensity gradually increasing to maximum capacity.
- Analyzes 23+ biomarkers with high accuracy
Cardiovascular fitness, fat-burning efficiency at various intensities, respiratory capacity, metabolic zones and biological age.
- Customization delivers tailored workout strategies to boost metabolism.
- Monitoring: Used to track progress in fat loss, athletic performance, and recovery.
Resting Metabolic Rate (RMR) Test
- Measures the calories burned at rest and metabolic efficiency.
- 30 minute initial consult
- A 10–15 minute, non-invasive, seated or lying test using a breathing mask.
- Analyzes 23+ biomarkers with high accuracy
Total calories burned at rest, fat/carbohydrate utilization, and metabolic capacity.
- Customization delivers tailored nutrition.
- Monitoring: Used to track progress in fat loss, athletic performance, and recovery.
Complete Assessment (AMR/RMR)
