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.

“Everything looks normal.” |
Let’s break this down and find out what your body is showing us. |
Approach |
Manage symptoms or wait for diagnosis |
Identify dysfunction early, correct the foundation, then optimize |
Testing |
Basic bloodwork |
GI-MAP, DUTCH, Metabolomix+, TruAge, food sensitivity, cortisol, custom bloodwork, and more when appropriate |
Treatment |
Generic medication or referral |
Personalized protocols, hormone support, supplements, peptides, bioregulators, nutrition, and lifestyle strategy |
Follow-up |
“Come back in six months.” |
Quarterly labs, regular reviews, symptom tracking, and protocol adjustments |
Goal |
Keep you out of disease range |
Improve how you feel, function, recover, perform, and age |
We review your symptoms, health history, goals, and concerns to determine the best next steps.
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.
You should not have to wonder whether your plan is working.
You should be able to see it.
Physician-led care. Functional medicine strategy. Long-term optimization.
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.

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.
Not just appointments. A relationship with a team that tracks your biology over time.
Yes. HFW uses functional medicine principles, advanced diagnostics, personalized protocols, and ongoing biomarker tracking.
We also include conventional medical oversight, prescription support when appropriate, hormone optimization, peptide therapy, bioregulators, and long-term clinical monitoring.
Physician-led means your care is supported by a clinical team that includes medical oversight, advanced functional medicine strategy, and provider-guided protocol development.
Dr. Saul Maslavi, MD, serves as Medical Director. Christina Warner, APN, NP-C, brings 25 years of clinical experience in women’s health, hormones, gut health, and root-cause care. Dr. Eric Landi, KICP, supports advanced functional testing, peptide therapy, and longevity protocol strategy.
Most traditional visits focus on disease diagnosis and symptom management.
HFW focuses on why you feel the way you feel before disease becomes the only thing that gets attention. We evaluate gut health, hormones, metabolism, inflammation, nutrient status, mitochondrial function, stress physiology, biological aging, and clinical trends over time. The goal is to maximize healthspan and get your body functioning in an optimal state.
Because standard labs often look for disease-range abnormalities.
Many patients are symptomatic long before their numbers become alarming. HFW looks beyond basic ranges and evaluates patterns, trends, advanced markers, and how your symptoms connect across multiple systems.
Yes. HFW is built as a telehealth-first practice.
Consultations happen virtually. Lab kits can be shipped to your home, and bloodwork can be coordinated locally through Quest/Lab-corp when needed. Prescriptions, supplements, and compounded medications can be managed through appropriate pharmacy partners when clinically indicated.
No. HFW serves patients nationwide through telehealth.
Some services, labs, prescriptions, and clinical recommendations may vary depending on state-specific rules and clinical fit.
Testing may include comprehensive bloodwork, GI-MAP stool analysis, DUTCH hormone testing, Metabolomix+ nutritional testing, TruAge and TruHealth biological age testing, IgG food sensitivity testing, Adrenocortex Stress Profile, genetic testing, DEXA or bone density testing, and custom panels when appropriate.
Testing is selected based on your symptoms, history, goals, and provider recommendations.
No.
Peptides and hormone therapy are tools, not default treatments. They may be considered when clinically appropriate, after reviewing your symptoms, testing, health history, safety markers, and goals.
HFW’s approach is to correct the foundation first, then layer in advanced therapies strategically when they make sense.
HFW generally operates on a cash-pay model, though some services such as bloodwork may be covered by insurance 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 rules, which do not typically cover pro-active treatment.
HFW is best for proactive patients who want deeper answers, are willing to complete testing, value long-term health, and want a clinical partner who will track their biology over time.
It is not the right fit for patients looking for emergency care, quick fixes, or one-size-fits-all protocols.
