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.

Symptoms matter. So does your history, stress, sleep, digestion, hormones, weight changes, medications, previous labs, family history, energy patterns, and what has already failed. Most patients have been talked over. We start by listening.
Standard labs rarely tell the whole story. HFW may evaluate gut health, hormones, cortisol rhythm, nutrient status, mitochondrial function, inflammation, metabolic markers, biological age, and genetics when clinically appropriate. Better data creates a better plan.
We do not look at hormones without looking at stress. We do not look at weight without looking at insulin. We do not look at fatigue without looking at mitochondria. We do not look at gut symptoms without looking at inflammation. The body cannot be treated in pieces.
Correction comes first. Optimization comes next. Before aggressively optimizing performance, recovery, hormones, or longevity, we often need to address gut dysfunction, inflammation, nutritional deficiencies, poor sleep, immune imbalance, or mitochondrial stress.
Your plan is not copied from another patient. It is built around your symptoms, labs, risks, goals, history, budget, and response over time. Depending on your needs, your protocol may include nutrition, targeted supplementation, gut restoration, or hormone optimization when clinically appropriate.
Most care stops after the plan is handed to you. HFW starts there. We use quarterly labs, symptom tracking, biomarker review, and ongoing protocol adjustments to see what is working, what is not, and what your body needs next.
You should not have to wonder whether your plan is working.
You should be able to see it.
Holistic care means looking at the systems that shape how you feel every day.
| Foundation | Why It Matters |
|---|---|
Gut Health |
Gut dysfunction can affect inflammation, immune activity, nutrient absorption, hormones, brain fog, skin, and metabolism.
|
Hormonal Health |
Estrogen, progesterone, testosterone, thyroid, cortisol, insulin, and DHEA influence energy, mood, sleep, libido, weight, and recovery.
|
Cellular Function |
Cellular stress can affect repair, resilience, energy production, inflammation regulation, and aging.
|
Metabolic Health |
Blood sugar, insulin, lipids, liver markers, body composition, and metabolic flexibility shape long-term health.
|
Inflammation |
Chronic inflammation can drive pain, fatigue, brain fog, hormone disruption, poor recovery, and accelerated aging.
|
Mitochondrial Function |
Your mitochondria produce cellular energy. When they struggle, fatigue, poor recovery, and metabolic resistance often follow.
|
Immune Function |
Immune imbalance may contribute to reactivity, autoimmunity, infections, inflammation, and poor resilience.
|
Detox Pathways |
Liver, kidney, lymphatic, and cellular detox pathways influence hormone clearance, inflammation, energy, and recovery.
|
Stress Resilience + Cognitive Function |
Cortisol rhythm, sleep, nervous system regulation, mood, memory, focus, and recovery all affect how your body functions.
|
Holistic care means looking at the systems that shape how you feel every day.
We test what most weight loss programs ignore.

|
Genetic Testing
|
Nutrient processing, detox pathways, inflammation tendencies, hormone metabolism, cardiovascular risk, and long-term personalization
|
|
DEXA / Body Composition When Appropriate |
Bone density, lean mass, fat mass, visceral fat, skeletal aging, and body composition trends
|
|
Custom Blood Panel
|
A targeted panel built around your symptoms, health history, medications, protocol, and goals
|
We review your symptoms, health history, lifestyle, goals, and previous care to understand what has been missed, overlooked, or left unresolved.
Advanced testing helps identify underlying imbalances across hormones, gut health, metabolism, inflammation, thyroid function, nutrient status, and cellular health.
Your provider translates your results into a personalized roadmap with clear priorities and recommendations for improving how your body functions as a whole.
We address the root causes of your symptoms through targeted nutrition, lifestyle strategy, hormone support, gut restoration, supplements, medications, or advanced therapies when clinically appropriate.
Your plan may include dietary guidance, targeted supplements, hormone support, peptide therapy, bioregulators, medications, or advanced therapies when clinically appropriate, with ongoing monitoring.
Regular follow-ups, biomarker tracking, and plan adjustments help you maintain progress and support long-term health, energy, resilience, and longevity.

Christina Warner, APN, NP-C
Christina Warner brings 25 years of clinical experience and a deeply personal understanding of what it means to be dismissed by a system that does not always see the whole person.
Her work is shaped by her own experience with life-threatening postpartum heart failure and later uncovering Bartonella as a hidden driver behind neurocognitive symptoms affecting mood, memory, focus, and daily function.
Those experiences shaped her belief that the body cannot be treated in pieces.

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.
We will not tell you that you are fine just because your labs are not alarming.
Book a free virtual consultation with HFW Longevity to discuss your symptoms, goals, health history, prior labs, and whether our holistic, functional, data-driven telehealth model is the right fit for you.
A holistic doctor looks at the whole person instead of treating symptoms in isolation.
That means evaluating how your gut, hormones, metabolism, inflammation, stress, sleep, immune function, nutrient status, mitochondrial health, and cellular aging may be connected.
At HFW, holistic care is also data-driven. We use advanced testing, clinical oversight, and ongoing monitoring to build a personalized plan around your biology.
No.
At HFW, holistic care does not mean rejecting conventional medicine. It means using conventional medical oversight alongside functional medicine, advanced diagnostics, nutrition, lifestyle strategy, hormone optimization, peptide therapy, bioregulators, and long-term biomarker tracking when appropriate.
Conventional medicine is essential for emergencies, screenings, acute care, and disease management. HFW helps complete the picture for patients who still feel unwell despite being told their labs are normal.
Your primary care doctor usually runs standard panels, screens for disease, manages medications, and refers you to specialists when needed.
HFW looks at the full picture of how your biology is functioning — gut health, hormone metabolism, nutrient status, mitochondrial output, inflammation, cellular aging, metabolic health, and clinical trends over time.
The goal is not only to manage disease. The goal is to optimize how you feel, function, recover, and age.
Yes.
HFW is not a replacement for emergency care, acute care, cancer screening, urgent symptoms, or your primary care relationship.
We are best used as a proactive, root-cause, optimization-focused clinical partner for patients who want deeper testing, long-term tracking, and a more complete view of their health.
Testing may include comprehensive bloodwork, GI-MAP stool analysis, DUTCH hormone testing, Metabolomix+ nutritional testing, TruAge + TruHealth biological age testing, NAD+ testing, Adrenocortex Stress Profile, IgG food sensitivity testing, organic acids testing, genetic testing, DEXA/body composition, and custom blood panels when appropriate.
Testing is selected based on your symptoms, history, goals, and clinical fit.
Yes.
“Normal” often means your numbers are not outside a disease-range reference interval. It does not always mean your body is functioning optimally.
Standard labs may miss gut dysbiosis, hormone metabolite patterns, cortisol rhythm disruption, nutrient deficiencies, mitochondrial stress, early insulin resistance, immune reactivity, inflammation patterns, and biological aging markers.
At HFW, prescriptions may be considered when clinically appropriate and legally available.
Your plan may include prescriptions, hormone therapy, supplements, peptide therapy, bioregulators, nutrition strategy, lifestyle support, or pharmacy coordination depending on your testing, history, symptoms, safety markers, state rules, and provider judgment.
No therapy is automatic.
Patients often come to HFW for fatigue, brain fog, weight resistance, bloating, food sensitivities, hormonal changes, menopause symptoms, poor sleep, mood changes, inflammation, low libido, thyroid concerns, chronic stress, poor recovery, autoimmune patterns, gut symptoms, and multi-system complaints that standard care has not fully explained.
We do not assume one symptom has one cause.
We look at how systems connect.
Yes. HFW is 100% telehealth.
Consultations happen virtually. At-home test kits can be shipped to you, bloodwork can be coordinated locally when needed, and eligible prescriptions may be managed through appropriate pharmacy partners.
HFW operates on a cash-pay model. HSA and FSA cards are accepted where applicable, and all major credit and debit cards are accepted.
This model allows more time, deeper testing, ongoing monitoring, and proactive care that is not limited by insurance-based sick-care rules.
Some patients notice early improvements in energy, digestion, cravings, sleep, mood, brain fog, or inflammation within the first few weeks.
More chronic or multi-system dysfunction may take longer. Your timeline depends on your root causes, hormone patterns, gut health, inflammation level, nutrient status, stress load, consistency, and care plan.
Our goal is measurable, sustainable progress — not temporary quick fixes.
