If your labs come back normal but you still feel exhausted, foggy, or hormonally off, that answer is not enough. Something is still driving those symptoms. At our Staten Island practice, Dr. Marina Fest, DNP, starts every patient relationship by asking one question: why is this happening?
That question is the foundation of every root cause health evaluation we do. Our practice is built on one idea: Functional Medicine That Gets to the Why. We do not skip straight to a prescription. We take the time to understand your full picture before recommending anything.
How We Find What Conventional Care Often Misses
Most appointments focus on matching a symptom to a diagnosis. That works for some situations, but it leaves a lot of patients stuck. If you have been told everything looks fine, yet you still do not feel well, the issue is usually something that standard care was not designed to find.
Dr. Fest takes a different approach. She evaluates digestion, hormones, metabolism, inflammation, and lifestyle factors together, because these systems do not work in isolation. Finding the real driver of your symptoms means looking at all of them.
Step One: Your Full Health History
The evaluation begins with a thorough review of your medical background, lifestyle, stress patterns, environmental factors, and how your digestion and hormones have been functioning. Dr. Fest also reviews any prior labs you bring in. She is not there to dismiss them but to see what they may be missing.
This conversation is not rushed. We built the time in because a care plan built on incomplete information will not hold up. You will not feel like you are being moved through a conveyor belt.
Step Two: Advanced Testing, Only When Warranted
Specialized testing is only ordered when there is a clear clinical reason for it. When it is appropriate, Dr. Fest may recommend GI-MAP microbiome analysis, a DNA-based stool test that identifies harmful pathogens, bacterial imbalances, inflammation markers, and digestive function across your gut microbiome.
She may also order comprehensive hormone panels, micronutrient testing, or inflammatory and immune markers, depending on what your evaluation reveals. Every test exists to generate data that actually changes your care plan, not to run numbers for the sake of it.
Step Three: A Protocol Built Around Your Biology
Once Dr. Fest has your evaluation findings and any relevant test results, she builds a care plan around your specific biology and health priorities. This may include targeted nutritional strategies, precision supplementation, gut restoration, hormone optimization, or lifestyle and stress modulation.
Most chronic symptoms do not have a single cause, so most protocols address more than one area. Every recommendation comes with an explanation. Understanding your plan is part of the process, not an afterthought.
Step Four: Ongoing Monitoring and Adjustments
Your care does not stop after the first visit. Dr. Fest schedules regular follow-ups to track your progress, adjust your protocol as your body responds, and review updated lab results when needed. This is how sustainable health actually gets built.
Established patients can also access select services through telemedicine. Whether you are coming in person from Staten Island or connecting remotely from Florida, continuity of care stays in place throughout your health journey.
Ready to Stop Guessing and Start Getting Answers
If you have seen multiple providers and still feel stuck, this evaluation was designed for exactly that situation. Dr. Fest sees adults and teenagers aged 14 and older at our Staten Island location. Florida patients are welcome through telehealth.
We are honest about fit. If you want a one-time visit or a quick prescription without a deeper look, our model is not the right match. But if you are ready to find out what is actually driving your symptoms, we are ready to start looking with you.

What happens at my first appointment?
Dr. Fest reviews your full medical history, current symptoms, wellness goals, and any prior labs. A physical exam is included where clinically appropriate.
