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.

“Your future health is being built right now. HFW helps you catch decline early,
correct what’s breaking down, and increase your lifespan.”
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?”
Weight Gain & Metabolic Resistance
But something was wrong. It just required the right tests and right attention to find it.
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.

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.

From your first conversation to long-term optimization.
Five steps, zero guesswork.
A private virtual conversation about your symptoms, health history, goals, medications, hormones, digestion, sleep, weight changes, and whether HFW is the right fit.
Advanced testing helps uncover the underlying factors affecting your health and identify where to focus first.
Your provider translates your results into a personalized roadmap with clear priorities and recommendations.
Your care plan focuses on addressing the underlying imbalances identified through your evaluation.
Your personalized plan may include nutrition, lifestyle strategies, supplements, medications, or advanced therapies when clinically appropriate, with ongoing monitoring.
Regular follow-ups, progress tracking, and plan adjustments help you sustain results and support long-term health.
We test what others ignore. These are the tools that find the real answers.

25 years of clinical experience; board-certified in Women’s Health via NCC. Pioneered the integration of GI-MAP testing and functional medicine into the practice.
Rejects the conventional “pieces” approach after surviving postpartum heart failure and overcoming chronic Bartonella. Focuses on optimal biomarker numbers, not just “normal” lab averages.
Believes “normal” labs merely reflect population averages rather than true health. Focuses on obsessive biomarker tracking to stop chronic dysfunction before it starts.

My husband has been working for years with Dr. Landi in both chiro and functional medicine. He is so happy with the results and passionate about working with Dr. Landi I had to follow! As a women in peri-menopause I experienced issues with weight gain, low energy and aging. The peptides Dr. Landi custom recommended have been a game changer. His expertise plus amazing bedside manner and caring nature are a rare blend. I highly recommend!

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.
Kevin Heckman
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.
Your primary care doctor runs standard panels, checks for disease, and manages what’s already broken. We look at the full picture of how your biology is functioning — cellular aging, gut health, hormone metabolism, nutrient status, mitochondrial output — and build an optimization strategy before dysfunction progresses to disease. We test what most doctors don’t know to order.
We use GI-MAP stool analysis, DUTCH Complete hormone testing, Metabolomix+ nutritional panel, TruAge/TruHealth biological age testing, NAD+ level testing, Adrenocortex Stress Profile, IgG Food Sensitivity Explorer (190+ foods), and custom comprehensive blood panels. All testing is shipped directly to your home.
Standard labs measure a narrow range of blood markers and check them against population averages. They miss gut infections, hormone metabolite patterns, adrenal dysfunction, cellular nutrient deficiencies, and epigenetic aging. Our testing is designed to find what others overlook, which is exactly why patients come to us after years of being told “it’s all in your head” or “everything looks fine.”
Many patients notice meaningful changes within two to four weeks of starting their protocol. Certain conditions — depending on their chronicity and root cause — take longer. Biological age improvement is tracked quarterly. Our approach is built for sustainable, measurable progress, not quick fixes that don’t last.
Yes. Every HFW patient moves through a defined framework: Forensic (testing) → Blueprint (protocol design) → Activation (implementation) → Optimization (ongoing monitoring). You’ll always know where you are, what you’re doing, and why.
We operate on a cash-pay model. HSA and FSA cards are accepted. We’ll provide documentation to support any applicable insurance reimbursement. This is an investment in proactive, data-driven care — the kind that insurance-based medicine structurally cannot offer.
Never. HFW is 100% telehealth. Lab kits come to your door. Consultations happen via HIPAA-compliant video. Your prescriptions are managed through our compounding pharmacy partners and shipped to you. There is no waitlist, no commute, and no referral required.
We serve patients nationwide (USA) through our telehealth platform.
