You Deserve
A Longer Story
The medical team you thought you already had. Advanced diagnostics that show what's actually going on inside you. A plan built around your biology — not a twelve-minute checklist. This is what healthcare was supposed to be.
The Problem
Mainstream Medicine Is Reactive.
Your Biology Isn't.
You get 12 minutes with a doctor who's juggling insurance codes and liability checklists. You get a prescription that manages symptoms. You get referred to a specialist who sees one piece of you and ignores the rest. And then you're sent home to figure it out on your own.
Your body is one interconnected system — your hormones affect your metabolism, your spine affects your energy, your gut affects your brain, your sleep affects everything. Treating one piece in isolation doesn't work. You need a medical team that sees the whole picture, has the tools to measure what's actually happening inside you, and has the freedom to use the best available treatments — not just the ones an insurance company approves.
Why This Works When Nothing Else Has
Hear Peter's story — how he faced a serious diagnosis, found that conventional medicine didn't offer the options he wanted, and built the practice he wished he'd had.
200+ Biomarkers. Not 15.
Your annual physical checks the basics. We check everything — hormones, metabolic markers, inflammatory signals, nutrients, genetic risk factors. The full picture.
One Team. Your Whole Body.
You don't need five different specialists who never talk to each other. Our physicians, nurse practitioners, and therapists work together — on you.
Treatments Your Doctor Can't Prescribe
Insurance limits what your PCP can offer. We use peptide therapy, regenerative medicine, advanced hormone optimization, and longevity protocols that most practices don't even know about yet.
Real Medical Oversight. Not a Prescription Mill.
Every protocol is designed by our physician team, monitored with real lab work, and adjusted as your body changes. This isn't telehealth with a rubber stamp.
Transparent Pricing. No Insurance Games.
You see exactly what everything costs before you commit. No surprise bills. No co-pay confusion. No "let's see what insurance says."
A Doctor Who Actually Knows You
Your medical team knows your history, your goals, and your biology. You're not patient #4,327 — you're the person they spoke with last Tuesday about your cortisol levels.
The Four Pillars
DECODE→RESTORE→OPTIMIZE→SUSTAIN
Every protocol, every service, every treatment at Longitude Life maps to one of four phases. It gives your care a clear logic — and tells you exactly where you are in your transformation.

What You Get That You're Not Getting Now
Time
Your appointments are 45-60 minutes — not 12. We don't rush through your visit because an insurance company decided that's all you're worth.
Depth
We test over 200 biomarkers — hormones, metabolic markers, inflammatory signals, nutrient levels — the panel your regular doctor doesn't run. And then we actually sit down and explain what they mean.
Freedom
We answer to you — not to an insurer. That's why we can prescribe the treatment that actually works, use advanced regenerative therapies, and build a protocol around your biology instead of a billing code.

What Our Members Say
For years I was told my fatigue was 'just stress' and my weight gain was 'just aging.' Longitude Life ran labs my doctor never ordered and found the actual problem. Within three months I felt like a different person.
Sarah M.
Precision Protocol Member
I've spent more on specialists who never talked to each other than I spend here in a year. One team, one plan, and they actually know who I am when I walk in.
James R.
Longitude Protocol Member
The transparency alone is worth it. I know exactly what everything costs, my medications are included, and I have a doctor I can actually reach. This is how healthcare should work.

Precision Protocol Member
Common Questions
Do you accept insurance?
No — and that's by design. Insurance companies limit what tests your doctor can order, how long appointments can be, and which treatments get approved. By working directly with you, we have the freedom to provide the level of care that actually changes outcomes. Our memberships are HSA/FSA eligible.
What makes this different from concierge medicine?
Most concierge practices charge for access to a doctor but still practice conventional medicine. We combine dedicated physician access with advanced diagnostics (200+ biomarkers, genomic screening), regenerative therapies, and longevity protocols that most practices don't offer at all.
How much does it cost?
Our Precision Protocol starts at $499/month with a $200 monthly medication credit included. That covers your labs, treatments, coaching, and most medications. Most Americans spend $9,000-$20,000 per year on premiums plus deductibles before insurance covers much of anything — our membership often costs less with dramatically better care.
What if I just want peptides?
The Peptide Club is $249 every 6 months — it includes comprehensive labs, a medical evaluation, protocol design, injection training, and ongoing monitoring. It's a great way to experience physician-directed care before committing to a full protocol.
Where are you located?
We're at 101 West Park Drive, Suite 100 in Brentwood, TN (just south of Nashville). Monday through Friday, 8:00 AM to 5:00 PM, with Saturday appointments available.
See What's Actually Going On
Most people leave their first conversation surprised by how much their current care has been missing. No pressure, no obligation — just a clear picture of where you stand and what's possible.
