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.

What they look at
Support
Your gut is connected to your whole system.
| What We Evaluate | Why It Matters |
|---|---|
|
Microbiome Balance
|
Dysbiosis can affect digestion, inflammation, immune activity, metabolism, and gut-brain signaling.
|
|
Pathogens & Overgrowth
|
Hidden bacterial, parasitic, or fungal patterns may contribute to bloating, discomfort, irregular stools, and inflammation.
|
|
Gut Barrier Integrity
|
Intestinal permeability markers may help explain food sensitivity patterns, immune activation, and systemic symptoms.
|
|
Digestive Function
|
Enzyme output, protein breakdown, fat digestion, and absorption all affect how well your body uses food.
|
|
Inflammation
|
Gut inflammation can drive bloating, fatigue, brain fog, skin issues, immune activation, and metabolic dysfunction.
|
|
Nutrient Status
|
Poor absorption can leave you deficient even when you eat well or take supplements.
|
|
Stress & Cortisol Patterns
|
Chronic stress can affect motility, gut repair, reflux, inflammation, sleep, and the gut-brain connection.
|
|
Hormonal Health
|
Thyroid, estrogen, progesterone, testosterone, and cortisol can influence digestion, bowel regularity, and inflammation.
|
|
Mitochondrial Function
|
Your gut lining and digestive system require cellular energy to repair, regulate, and function well.
|
|
Metabolic Health
|
Blood sugar, insulin, inflammation, and gut health often influence each other more than most patients realize.

A realistic plan designed around your symptoms, sensitivities, digestion, blood sugar, inflammation, stress, sleep, and actual life.
Nothing random. Nothing guessed.
We review your digestive symptoms, health history, lifestyle, and goals to understand what's affecting your gut health.
Advanced testing helps identify underlying gut imbalances, inflammation, microbiome health, and digestive function.
Your provider translates your results into a personalized roadmap with clear priorities and recommendations for restoring gut health.
We address the root causes of your symptoms through targeted gut restoration, nutrition, and personalized treatment strategies.
Your plan may include dietary guidance, targeted supplements, gut-healing protocols, medications or advanced therapies when clinically appropriate, with ongoing monitoring.
Regular follow-ups, progress tracking, and plan adjustments help you maintain a healthier gut and support long-term digestive wellness.
Gut healing is not a 7-day reset.
It is a rebuilding process.

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.
Let’s find out what your gut is actually trying to tell you.

GI-MAP is a stool-based molecular test that measures selected microbes and pathogens, H. pylori, digestive function markers, gut inflammation markers, immune activity, and intestinal barrier-related markers depending on the panel. HFW uses it for selected patients when the result could change diet, supplement, conventional workup, referral, or monitoring priorities. It does not explain every symptom on its own.
GI-MAP is $813 for nonmembers, covering the test and the clinician review together. Longevity Membership members are entitled to additional discounts. GI-MAP is also included in the $1,250 Health Blueprint and in the $1,050 TruHealth plus GI-MAP package.
Yes, and it is a common situation. A colonoscopy and a standard panel are designed to find structural disease and major abnormalities, and they do that well. They are not designed to describe digestive function, microbial patterns, or inflammation at the level a functional workup considers. HFW starts by confirming that conventional evaluation is complete and appropriate, then selects testing that could change the plan. If your presentation suggests something needing conventional diagnosis, HFW refers.
No. Detecting an organism or a marker does not automatically prove causation, disease, or the need for treatment. Results are interpreted alongside your symptoms, history, diet, medications, and other evaluation. Treating every detected finding is a common mistake and one HFW deliberately avoids.
Digestive function can be one contributor among several to energy, cognition, skin, and hormone-related symptoms, and evaluating it can be worthwhile when symptoms span more than one system. That is different from claiming the gut explains everything. HFW treats it as a possible contributor to investigate, not a definitive answer.
Probiotics and elimination diets are reasonable first steps, but they are usually applied generically. HFW’s approach is to define the specific question first, review what you have already tried and how you responded, select testing when the result would change the plan, then prioritize. Sometimes the useful finding is not what you expected, and sometimes the right next step is conventional evaluation rather than another supplement.
HFW can help investigate these symptoms and build a prioritized plan. That is different from diagnosing or treating a specific disease. Any presentation that suggests a condition requiring conventional diagnosis, urgent evaluation, or specialist care is referred, and HFW does not replace gastroenterology care.
Generally, someone with persistent digestive symptoms, someone whose symptoms span multiple systems, or someone in corrective care where a gut finding could change diet, supplement, referral, or monitoring priorities. Not everyone needs it. If the result would not change what your clinician does next, it is not worth buying.
Yes. GI-MAP is an at-home collection. HFW mails you a kit, you collect the sample at home following the instructions provided, and you mail it back to the laboratory. There is no lab visit required.
Depending on the panel, selected microbes and pathogens, H. pylori, markers of digestive function, markers of gut inflammation, immune activity, and markers related to intestinal barrier function. What it measures and what it means are two different things, and the second requires clinical interpretation.
No. Detecting an organism or an elevated marker does not automatically establish the need for treatment. Treating every detected finding is a common error, and it is one HFW deliberately avoids.
Because the report contains a lot of individually flagged values, and reacting to each one produces an overwhelming and often unnecessary plan. Interpretation means deciding which findings matter for you, in what order, and whether any of them point toward conventional evaluation instead.
