“The ICU does not show you what killed people. It shows you what failed them years before.”
A Member’s Story
“
I have been very focused, until now, on my family and career. It’s a typical story for someone successful in the business world. Their physical health takes a back seat.
Paul Backman
Paul is 54. He runs a company helping farmers grow food sustainably.
When his first granddaughter arrived, he decided it was time to take control of his health. He came to us for the plan he had put off building for himself.
His first step was a VO2 Max test. Data first, then a plan built around it. A few months in, energy that shows up at 4 PM instead of leaving, and workouts he actually looks forward to.
Paul is married to Tammy Backman, our Operations Director.
Does This Sound Familiar?
You know something is off. Your labs came back “normal.”
You have told a doctor how you feel. You have been sent home with a clean panel. You are not imagining it. Standard labs measure eight or ten things. Your biology has hundreds of signals worth reading, and drift shows up in the ones nobody is looking at.
Waking up tired
You’re getting the hours, but you don’t feel rested. Your energy crashes by mid-afternoon.
Slower recovery
Workouts leave you sore longer. Weight is harder to shift. Your body composition is drifting.
You're not as sharp as you used to be
Names take longer. Focus slips in the Monday meeting that used to feel easy. Nothing is clinically wrong. That’s exactly the problem.
Mood and drive
Motivation feels dulled. Libido has changed. Something’s different and you can’t quite name it.
Belly weight that won't move
Same food, same training as before, and the scale won’t cooperate. Something metabolic has shifted.
Sleep isn't restoring you
You fall asleep fine but wake up already tired. Not sure if the sleep itself is broken or something upstream is.
These are the reasons people come to us. These are what we look at first.
The clinic that measures, and shows you what changed.
A snapshot on day one. Retesting built around your plan and your results, not a fixed calendar. The plan sharpens as the data does.
60+
Biomarkers, read together as a trajectory
DEXA
Body composition, bone density, lean mass
VO2 Max
Cardiorespiratory fitness, one of the strongest predictors of long-term health
RMR
Resting metabolic rate, calibrated to your body
Sleep
At-home sleep study read by a board-certified sleep physician
Hormones
Full panel, men and women, treated only when clinically indicated
Genome
Whole-genome sequencing, read against your clinical picture
Retest
Timed to your plan, not a fixed calendar. Direction, not a single number
Testing is the beginning. What you get is a physician who reads it in context and a team that stays with you as it changes.
How We Work Together
A different kind of medicine, from the first conversation onward.
You are not a chart. You have a specific biology, a specific history, and specific goals for the decades ahead. Here’s how the work unfolds.
1
A free Discovery Call.
Thirty minutes with our team. We listen for what’s actually going on, and figure out together whether this is the right next step for you.
2
Your Consult with your provider.
A 60-minute visit where your provider reviews your full picture, walks you through where your reserve stands today, and shows you what the years ahead can look like with the right work. The Consult includes labs that most patients have never had run before with any other doctor.
3
The Reserve Program begins.
Once you enroll, the work goes deeper. More comprehensive labs and testing get layered in around the plan your provider builds specifically for you, alongside an at-home sleep study when indicated, DEXA, VO2 Max, and coaching.
4
The plan evolves, then shifts to membership.
We re-test what matters, adjust what needs adjusting, keep the plan honest. Once your program is complete, most patients move into an ongoing membership built to maintain what you’ve achieved.
The Programs Built On What We Find
The tools behind the plan.
Every service exists to answer a specific question about your biology. None of them stand alone.
The Reserve Program
The anchor of the practice. A 9-month, physician-guided program built around the framework Dr. Jarbou has spent his career developing. Sleep, hormones, metabolic health, cognition, and recovery, read together and treated as one connected system. Ongoing membership picks up after the program.
Sleep Medicine
At-home sleep studies read by a board-certified sleep physician. Sleep architecture is one of the strongest levers for how your brain, metabolism, and energy hold up over the next decade. Most testing stops at “you don’t have apnea.” Ours doesn’t.
Hormone Replacement Therapy
For men and women whose systems have started to drift. We test before we treat, and we address sleep, movement, and nutrition first.
Genetic Testing
Whole-genome analysis Dr. Jarbou reviews against your clinical picture. Risk you can act on, not a raw data dump.
GLP-1 Weight Loss
A physician-led evaluation before any prescription. We look at metabolic markers, sleep, and current health context first, then build a plan that fits what your biology is actually asking for.
Ongoing Membership
What comes after the Reserve Program. A continuity layer to hold the gains you made and keep the plan moving as your life and body change. Members stay connected to their clinical team and coach.
The Reserve Program
Want everything in one program?
The Reserve Program is nine months of physician-led care, testing, and coaching, then a smooth move into your membership. Book a conversation to see if it’s right for you.
Book a ConversationAnother Member’s Story
Nancy is a professor of English at the University of Missouri.
She had lived with poor sleep for years and worked around it. When she came in, she wasn’t looking for a miracle. She was looking for someone who would take her sleep seriously.
Dr. Jarbou built her plan around what her data showed. She wants to swim, race, hike, bike, garden. She talks about the next decade as an expansion, not a shrinking.
“
I'm 61, but I feel 31. I'm seeing this next phase of life as full of possibilities rather than compromises and concessions.

Meet Your Founders
Two disciplines. One clinic.
Dr. Jarbou and Marmar met and immediately clicked over a shared belief: prevention beats reaction. Test what your annual physical misses. Track sleep, exercise, and heart rate variability. Don’t wait for the crisis to force your hand. That is the clinic they built.
Co-Founder & Medical Director
Dr. Mohammad Jarbou, MD
“The chart records where you are. It is silent on where you are going. That silence is the danger.”Sleep medicine is not a side credential here. Fragmented sleep raises cortisol; cortisol raises glucose; glucose drives visceral fat; visceral fat thickens the airway; the airway fragments sleep further. That loop is one of the earliest engines of decline, and it is the one most easily missed. It is the first thing Dr. Jarbou looks at. Author of Before the Alarm: What the ICU Reveals About Real Longevity (Reserve Press). Available now.
Board-certified in Internal Medicine, Pulmonary Disease, and Sleep Medicine.
20+ years of clinical practice
Dr. Mohammad Jarbou, MD, earned his medical degree from Damascus University Medical School, completed his residency in internal medicine at the University of Missouri in Columbia, and completed his fellowship at Washington University in St. Louis. He holds a master’s degree in clinical informatics and is the author of Before the Alarm.
Co-Founder & Master Coach
Marmar Atallah
Fifteen years coaching, 500+ clients through fat loss, strength, and metabolic health. Marmar runs the performance side of the clinic. VO2 Max and resting metabolic rate testing in the office, and the coaching that turns test results into a training and nutrition plan people actually stick with.
“Testing tells you what is happening in the body. Coaching is how you change it.”
His approach is built on his own story. A gym owner and new father during the pandemic, he watched his own body composition drift with the stress of running a business, then rebuilt it the same way he now rebuilds his clients: data first, then a plan that fits real life. Fitness is not separate from longevity here. It is one of the four pillars we test and train.

“My expectations were exceeded.”
They used my DNA to build a plan specifically for me. It felt like medicine designed for a person, not for a diagnosis code.
Dr. Nathaniel Murphey
“I feel really good.”
My sleep is deeper. My energy shows up in the afternoon instead of collapsing. It is the kind of change I had stopped believing I’d get.

“We have renewed hope.”
We came from a wellness clinic that got us weight-loss results at the cost of our overall health. The Longevity Clinic tested for a real baseline, then built a plan around where we wanted to be. Their goals lined up with ours.
