The story you were told about dementia is out of date.
You’ve probably heard what we were taught in medical school: dementia is genetic, it’s bad luck, and nothing can be done until memory starts slipping. The science now tells a very different story. 90% of the risk factors for cognitive decline are modifiable through physician-directed lifestyle protocols.
The brain changes behind Alzheimer’s can begin as many as 20 years before the first forgotten name. That means your 40s, 50s, and 60s aren’t a waiting room. They’re your window.

Your crystal ball
Look into your brain’s future — while you can still rewrite it.
Imagine knowing today the hidden factors that could quietly lead to dementia ten or twenty years from now. Not a guess based on family history. Real answers from your own blood, genes, and biology. Most people never see these numbers. You get to see them while every one of them can still change.
Early-warning brain signals
p-Tau 217, amyloid beta 42/40, NfL, and GFAP
Your genetic blueprint
APOE4 and critical risk genes, plus the IntellxxDNA Brain Optimization Panel (500+ variants)
Hidden inflammation & blood sugar
Comprehensive metabolic blood panel
Your cellular energy
NAD+ testing
Toxins quietly stressing your brain

Brain chemistry & hormones
Neurotransmitter and hormone evaluation
How your brain performs today
Professional cognitive performance testing
Testing included varies by package.
Every finding comes with a plan. This isn’t about bad news — it’s about finally knowing what to do.
We believe that, given the right conditions, the body does what it was made to do: repair, renew, and thrive. Cognitive decline isn’t a random sentence. It’s the downstream result of root causes — inflammation, blood sugar, gut health, toxins, sleep, hormones, and cellular energy. Find them, address them, and you give your brain the conditions to flourish for decades.
The mind is a gift worth fighting for.

“I lost 2 people I loved deeply to dementia — and I promised myself I would spend my career making sure that didn’t happen to anyone else I could reach.”— Dr. Lori King, MD
We watched dementia take our parents. We built PEAK so it doesn’t have to take you.
After 62 years in family medicine, we each lost a parent to dementia. We retrained in root-cause and longevity medicine to offer families the answers and support we wish our parents had.

PEAK has run a waiting list for much of 2026. We keep it small so every patient gets real physician time.
Healthspan, not just lifespan
This isn’t only about avoiding dementia. It’s about your next 30 years.
Cognitive longevity means being the one who remembers the grandkids’ recital, plans the trip, runs the business, finishes the crossword, and is still the person everyone calls for advice. The root causes we address for your brain also drive energy, sleep, weight, mood, blood pressure, and how fast you age.
Now imagine someone handed you a pill that made that future far more likely. You’d take it without a second thought.
There is no pill. But there is something just as powerful: the small choices you make every day. How and when you eat, how you move and sleep, the light you see, the toxins around you, how you handle stress, and the gratitude, nature, and connection in your life all reach down to your cells: your mitochondria, your cellular energy, your mind-body connection. Each choice either fuels your brain or quietly drains it.
PEAK puts a plan built for your body in your hands, along with the knowledge to choose with confidence. One choice at a time, the future you just pictured becomes something you build every day.
No — the best time is before anything shows. Most PEAK patients come because they want to keep it that way, often after watching a parent decline.
What if my results are frightening?
Every result arrives with a plan and a physician beside you. We look for risks so we can lower them, not to deliver a verdict.
I carry APOE4 or have a parent with dementia. Is it too late?
Genes load the dice; biology and lifestyle shape how they roll. Dr. Lori carries very high genetic risk herself — and has lowered her biological age by more than 10 years.
How is this different from my regular doctor?
Your physician spends real time with you every month, tests for what standard visits don’t, and addresses root causes rather than waiting for symptoms.
How much time does it take?
About an hour a week for your module and action steps, plus one virtual visit with your physician each month.
Can I do this from outside Texas?
All program visits are virtual, and we serve patients both locally and nationwide. Call us to confirm availability in your state.
Is it covered by insurance?
PEAK is cash-pay. Some patients use HSA or FSA funds, and we can provide documentation. 0% financing for up to 12 months is available through Cherry. See pricing and payment options →
Can my spouse join me?
Yes. Your spouse’s consultation is free when booked with yours, and if you both enroll, you each receive $500 off.
The climb begins now.
Your consultation isn’t a sales call. It’s one hour with Dr. Lori or Dr. Chris, reviewing your history and identifying your first risk factors. $350, credited in full toward the program if you enroll. Bring your spouse — their consultation is free.
For decades we cared for families in Southlake. Then dementia came into our own family, and it changed the kind of doctors we are.
Our story
Between us, we’ve practiced family medicine for 62 years. We each lost a parent to dementia, and we did everything conventional medicine taught us. It wasn’t enough, because what we had been taught was incomplete.
So we went back to learning. We retrained in root-cause and longevity medicine, applied it to ourselves first, and built PEAK so other families would have what ours never did: answers early enough to change the story.

Watch our story (20 min)
The video we wish someone had shown us when our parents were first diagnosed.
We know dementia as physicians, and as a daughter and son who watched a parent live with it. We did what we knew to do for our own families, but conventional medicine offered few ways to look for the underlying risks early or a clear path to change them.
That experience changed the questions we asked in our practice. We retrained in root-cause and longevity medicine, and built PEAK to bring families earlier testing, a physician who knows them, and practical steps to support brain health.
PEAK Cognitive Longevity is a physician-led, science-driven program that treats brain health as something to be measured, understood, and actively preserved. Using precision medicine, we evaluate each person's individual risk for cognitive decline, build a protocol designed for them alone, and walk beside them every step — protecting memory, sharpening the mind, and reclaiming the future with confidence.
We believe cognitive decline is far more preventable than most people are told, and that the mind is a gift worth fighting for. This is the climb, and we walk every mile of it beside those we serve.

“I lost 2 people I loved deeply to dementia — and I promised myself I would spend my career making sure that didn’t happen to anyone else I could reach.”— Dr. Lori King, MD
Dr. Chris King, MD
PEAK was built by Dr. Lori King and Dr. Chris King, the physicians of Timarron Family Medicine in Southlake, Texas. Between them they have more than sixty years in family practice — most of it spent doing conventional medicine well.
Several years ago they both retrained in root-cause and longevity medicine, because the conventional model had no useful answer to the question that mattered most to their own families.
In PEAK, you work directly with one of them.
Not a coach, not a care coordinator, not a protocol delivered by an app. Your own physician, every month, for six months.

What We Bring to Your Care
Advanced diagnostics paired with personalized care planning.
Evidence-informed strategies for long-term cognitive health.
Ongoing support for healthy aging as your needs evolve.
Root-cause identification instead of symptom management.
The Program
What PEAK Actually Includes
Six months. Two things happening at once: a personal clinical relationship, and a structured education that changes how you live.
Weeks 1–2
Testing
Advanced testing done largely from home. We measure your brain with four blood biomarkers, then look at the systems feeding into it: metabolic and cardiovascular health, gut health, vitamins and nutrients, hormones and neurotransmitters, cellular energy, and — depending on your tier — genetics, environmental exposure, and professional cognitive testing.
Weeks 3–4
Analysis & Protocol
Your physician reviews everything, then sits down with you for a full Review of Findings. Together you build a protocol targeting the specific root causes the testing found in you.
Months 2–7
The Climb
One educational module each week — 26 in total, across six monthly Basecamps covering inflammation, mitochondrial health, cellular energy, autophagy, and lifelong brain health. Expect about an hour a week to read and think it through — the action steps happen inside the life you already have.
Every Month
Physician Visit
A one-on-one virtual visit with Dr. Lori or Dr. Chris to adjust your protocol, review supplements, and answer questions. Between visits, you can message your physician directly, any time.
Four Brain Biomarkers, From a Blood Draw
Most brain-health programs never look directly at the brain. We do — with four blood biomarkers that together give a picture of what is happening in your nervous system right now. They are one part of a larger work-up: metabolic health, gut, hormones, nutrients, cellular energy, and, depending on your tier, genetics and toxic exposures are measured alongside them because those systems influence what the brain markers eventually show.
p-Tau 217 — the most reliable blood marker we have for Alzheimer's-type changes in the brain
Amyloid beta 42/40 ratio — whether amyloid is accumulating, and to what degree
NfL (neurofilament light) — a signal of nerve cell injury anywhere in the nervous system
GFAP — a measure of inflammation in the brain's support cells
No single one of these tells the whole story. Read together, they tell us whether anything is happening beneath the surface — years before it would show up in how you think or feel.
Most people go their entire lives without ever knowing where they actually stand. You don't have to be one of them.
At six months, you finish with a PEAK Graduation Session — a full look at what changed and what comes next. Most graduates continue with us into PEAK Ascent, our Year 2 program. That's a decision for later, not now.
A detailed breakdown of each monthly Basecamp and a full comparison of testing tiers is part of what we walk you through at your consultation.

Begin that day if it's right
Before we meet, you'll complete a detailed health and lifestyle history. It takes about thirty minutes and it covers ground a standard intake never touches — sleep, stress, diet, exposures, medications, family patterns, and the things you've noticed but never mentioned to a doctor.
Then we spend a full hour together, one to one, with a physician. We go through your history properly and begin identifying the risk factors that are specific to you.
No pressure, and no obligation. Whether or not you ever enroll, you’ll leave this hour knowing more about your brain than you ever have: your risk factors, what’s already protecting you, and what you can start doing today.
$350 — credited in full toward your program if you enroll
Refundable up to 48 hours before your appointment.
An hour of physician time with your complete health history is real clinical work, and we would rather do it properly than run free calls that serve no one well. If you join us, it costs you nothing in the end.
Loading the evidence behind PEAK...
The Evidence
The Research Behind PEAK
The 2024 Lancet Commission identified 14 modifiable risk factors and concluded that nearly half of dementia cases may be linked to factors that can change. PEAK translates that evidence into measurable clinical work across blood pressure, blood sugar, hearing, sleep, inflammation, activity, nutrition, and other contributors to brain health.
Our approach reflects the growing evidence that cognitive decline is influenced by whole-body health over many years. Testing does not predict a person’s future with certainty; it gives physicians an earlier opportunity to identify risks and build a targeted plan.
Established versus emerging
The 14 Lancet risk factors are well established. Other areas we work in — toxicant exposure, hormonal health, and the gut-brain axis — are actively studied and biologically plausible, but the evidence is not yet strong enough to say that treating them prevents dementia. We address them because they influence the systems that shape brain health, while staying clear about what the evidence can and cannot promise.
