24 pages on advanced testing, clinician-led protocols, and why strategy comes before any single compound.
But something was wrong. It just required the right tests and right attention to find it.
“Are you sick enough to diagnose?”
“How is your body functioning, what is changing over time, and what can we do now to improve your long-term health trajectory?”
HFW is a telehealth practice built around advanced diagnostics and root-cause treatment. We run the testing conventional visits skip, read it with you, and build a plan that gets adjusted as your biology changes.
Most of our patients arrive after years of being told nothing is wrong.
A plan built entirely around your biology — not a generic protocol. Depending on what your testing shows, yours may draw on any of these.
Every therapy is selected from your results and reviewed by an advanced care clinician. Nothing is prescribed off a template.
Longevity and Health Optimization
Aging is not only how many years you have lived. It is how your cells, hormones, and organ systems are actually performing. We combine biological age testing, organ-system data, hormone and metabolic panels, and quarterly biomarker tracking to show you how your body is aging, then build a clinician-guided plan to change that trajectory.

Weight Gain & Metabolic Resistance
Persistent weight gain, insulin resistance, and a sluggish metabolism often indicate deeper metabolic imbalances. Our approach focuses on identifying and addressing the root causes rather than masking symptoms. By optimizing your metabolic health, we help create sustainable, long-term results.
Gut Health
Menopause & Hormonal Health
Hot flashes, mood swings, and disrupted sleep often signal deeper hormonal shifts that go beyond menopause alone. Our approach focuses on identifying and addressing the root causes rather than masking symptoms. By rebalancing your hormones, we help create sustainable, long-term results.
Chronic Fatigue
Brain Fog & Cognitive Decline
Anxiety & Mood Disorders
Autoimmune Conditions
Hormone Imbalance
Real progress. Real support. No shame.

It’s been a blessing working with Dr. Landi and his entire team! After getting my test results, Dr. Landi walked me through a number of helpful steps to restore my health. He is very knowledgeable and uses an in-depth functional medicine approach in addressing health concerns. Bernadette is also very kind and thoughtful and I enjoy the interpersonal connection I have built with all of them.

I have been working with Dr Landi for several months now. He is extremely knowledgeable, attentive and responsive. He actually listens which is rare in medicine these days. I’m excited to see what the results are from my protocol in a couple of months. Highly recommend his practice if you’re looking into functional medicine.
Lauren Griffith
Dr. Landi is highly knowledgeable and skilled in the field of functional medicine, but he also possesses a genuine empathy and compassion that is so often lacking in the traditional healthcare system. Dr. Landi connects to each of his patients on a personal level, works with you every step of the way, and makes you feel supported while navigating challenging health obstacles.

I found out about the practice of Functional Dr’e last year and realized this is what I need! Finding Dr Landi so close to home was awesome. We appreciated his candor, knowledge and engaging personality. He exuded caring and interest in me and my situation. I feel he had repeatedly gone the extra mile for me so our collaboration is successful.
We test what others ignore. These are the tools that find the real answers.
TruAge — Biological Age Testing
Your birthday tells you how long you’ve been alive. TruAge tells you how fast you are aging. Reading three epigenetic clocks — OMICmAge, SymphonyAge and DunedinPACE — from a simple at-home blood spot, it reports your biological age, your pace of aging, and organ-system aging patterns. Available on its own at $500, or bundled with TruHealth.

Available on its own at $500, or bundled with TruHealth.
TruHealth — 105+ Biomarker Panel
TruHealth answers the other half of the question: what is driving how you feel. From the same at-home finger-stick sample, it reports 105+ biomarkers spanning vitamins and amino acids, omega-3 and lipid markers, glucose and metabolic markers, inflammation and immune cell ratios, neurocognitive markers, and toxin exposure. Available on its own at $450, or bundled with TruAge.
TruAge + TruHealth — Complete Longevity Panel
Run together, the two tests answer both questions at once: how fast you are aging, and the nutritional, metabolic, immune, and cognitive drivers behind it. One at-home collection covers both panels. $750 bundled — $200 less than ordering the two separately — and included in our Comprehensive Longevity Workup.
GI-MAP Advanced Stool Test
If you could run one test on every person over 40, this would be it. The GI-MAP is a comprehensive gut health panel that measures pathogens, dysbiosis, leaky gut markers, microbiome balance, and inflammation — producing a full year’s worth of actionable insights from a single collection. Bloating after meals, brain fog, weight resistance, chronic fatigue — all of these trace back to gut function more often than most physicians check.
DUTCH Plus Complete Hormone Test
The DUTCH Complete is not your standard hormone panel. It measures hormone metabolites — how your body actually processes and eliminates hormones — along with cortisol rhythm patterns throughout the day, melatonin, and comprehensive sex hormone data. Patients are routinely told their hormones are “normal” when deeper analysis would reveal clinically meaningful imbalances. This test finds them.
Metabolomix+ Nutritional Panel
Measures nutrient status, oxidative stress markers, amino acid levels, gut metabolites, and mitochondrial health — the cellular infrastructure behind your energy, recovery, mood, and immune function. Standard labs don’t touch this. The Metabolomix+ goes deep into the biochemistry of how your body is actually functioning at the cellular level.
NAD+ Level Advanced Test
NAD+ is one of the most critical molecules in the body for cellular energy production and healthy aging. Its levels decline significantly with age. This test measures your actual NAD+ concentration — giving us a precise target for cellular energy optimization and aging intervention.
Adrenocortex Stress Profile
Cortisol isn’t just a “stress hormone.” It governs your energy rhythm, immune modulation, sleep architecture, and metabolic function. This test maps your cortisol pattern across the day to evaluate adrenal output, identify adrenal fatigue patterns, and guide targeted intervention.
IgG Food Sensitivity Explorer
Tests immune reactivity against 190+ foods, identifying the hidden triggers behind chronic inflammation, digestive symptoms, skin issues, and energy crashes. Not the same as an allergy test — this identifies the slower, low-grade immune reactions that don’t cause immediate symptoms but silently drive systemic dysfunction.
Custom Blood Panel
A fully customizable blood panel built around your specific health goals and protocol. Includes key metabolic, inflammatory, hormonal, and biomarker assessments — tailored to where you are in your care plan.
For patients who want more than a one-time test or consultation. Membership creates an ongoing system: understand what is changing in your health, put a plan into action, measure progress, and adjust over time.

Heal From Within, also called HFW, is a clinician-led longevity and health optimization clinic with physician medical direction. HFW combines advanced testing, conventional and functional medicine, hormone and metabolic care, lifestyle intervention, accountability coaching, and selected therapies when clinically appropriate. The model is to measure first, identify priorities, correct meaningful dysfunction, optimize deliberately, and monitor over time. HFW is not a peptide storefront, a med spa, or a replacement for primary or emergency care.
A longevity clinic focuses on healthspan, meaning the years a person lives in good function, rather than only treating disease after it appears. At HFW that means advanced testing selected because it can change a decision, clinical interpretation by an advanced care clinician, a prioritized plan, implementation support, and repeat measurement over time. The output is a strategy that evolves, not a one-time report or a product order.
Traditional primary care is essential and is generally organized around diagnosing and treating disease once a problem becomes significant. HFW adds a proactive layer: advanced testing chosen for actionability, interpretation in the context of your goals and history, a prioritized sequence rather than a long undifferentiated list, coaching to support follow-through, and scheduled re-measurement. HFW works alongside your primary care doctor and does not replace primary, specialist, or emergency care.
A peptide clinic sells access to a compound and an online prescription company sells efficient access to a product. At HFW a request for a specific therapy starts an evaluation, not an order. An advanced care clinician reviews your goal, history, risk, and useful baseline testing before deciding whether a therapy, formulation, duration, and monitoring plan are appropriate. No therapy is guaranteed, and every continuation decision requires clinician review.
HFW tends to fit three kinds of people. First, someone without a diagnosis who wants to understand where their health is heading and act early. Second, someone with unresolved or multi-system symptoms that have not been fully explained. Third, someone with a specific goal such as metabolic health, hormone symptoms, body composition, energy, or recovery who wants clinician guidance rather than a product. Every patient starts with a complimentary introductory call to determine fit.
HFW may not be the right choice for someone who needs emergency or acute care, expects a prescription or peptide on demand, wants a guaranteed result, is unwilling to complete the evaluation or monitoring a plan requires, or needs a service outside HFW’s clinician licensure or state authority. The introductory call is where that is determined honestly, before anyone spends money.
No. HFW is designed to work alongside conventional care, not to replace it. You should keep your primary care physician, your specialists, your guideline-recommended screening, and emergency care. HFW adds advanced testing, interpretation, prioritization, and longitudinal monitoring on top of that foundation, and refers out when something belongs with conventional medicine.
No. HFW is self-pay and does not bill insurance for consultations, membership, programs, or therapies. Conventional bloodwork and other outside laboratory charges are separate, and the laboratory may have its own insurance or self-pay process. HSA and FSA funds are generally accepted, with eligibility determined by your specific plan.
The first step is free. A complimentary introductory call with an HFW advanced care clinician costs $0 and is used to understand your goals and identify the most appropriate starting point. From there, common starting points include the $450 initial TruHealth assessment, the $1,250 Health Blueprint, the $225 per month Longevity Membership with an initial 12-month commitment, and the 12-month Functional Medicine Corrective Program at $700 for month one and $350 per month thereafter. Conventional bloodwork, medications, peptides, and hormone therapy are purchased separately.
Most medical care is built to identify a problem once it is clearly a problem. That is appropriate and necessary, and HFW is not a substitute for it. What HFW adds is attention to the space before that point: how your markers are trending across repeat measurements rather than at one moment, patterns that sit inside the normal range but are moving in a direction worth watching, and symptoms that often get set aside because they do not map to a diagnosis. Acting earlier is not the same as preventing disease, and HFW does not claim to prevent disease. It means having information sooner, and more chances to change course.
HFW does not promise to reverse aging, prevent or cure disease, guarantee weight loss, guarantee a lower biological age, or guarantee that you will be approved for any particular therapy. What HFW commits to is a process: test when the result can change a decision, interpret clinically, prioritize what matters most, intervene responsibly, and reassess as your data and goals change.
It is HFW’s four-stage care model. Discover means understanding your goals, symptoms, history, medications, risks, and existing data, then testing where a result would change something. Correct means addressing meaningful dysfunction or foundational barriers first, because they affect whether later optimization is useful or premature. Optimize means selectively adding interventions aimed at healthspan, function, body composition, or resilience. Monitor means reviewing symptoms, adherence, safety, and biomarkers, then continuing, adjusting, pausing, stopping, or referring.
Testing is generally available nationwide. The exact treatment service depends on the patient’s state, clinician authorization, laboratory rules, pharmacy requirements, and the therapy involved. HFW also has a physical office where patients can be seen, though in-office visits are not typical — care is primarily delivered remotely via telehealth. HFW confirms availability for your specific situation during the introductory process, before you purchase anything.
