Functional medicine in Springfield, MO — holistic, integrative root-cause care
Treating the cause, not the lab value that finally went out of range.
Conventional panels are built to catch disease once it arrives. They are not built to explain why you have felt progressively worse for three years while every result came back technically normal. Functional medicine starts from the opposite end: measure widely, read the results as one connected system, and treat the upstream cause rather than managing each symptom as it appears.
This place is truly amazing. Teresa helped me after I couldn’t answers for years with severe migraines. The staff is very nice and helpful too.

Start here
What functional medicine actually is.
The plain version, because the term gets used loosely: functional medicine looks for the root cause of symptoms instead of treating each one in isolation — reading a wide panel of markers against each other to find what’s actually driving how you feel. Three terms travel with it, and not all of them mean the same thing.
Functional medicine
Root-cause, systems-based care
An approach that asks why a symptom exists and how the systems connect, rather than matching each complaint to a separate prescription. Practiced here by a licensed medical provider.
Root-cause
The core idea
Fatigue, weight, and mood are usually downstream of something measurable — thyroid, insulin, hormones, inflammation. Root-cause work treats that source, not just the symptom on top of it.
Not “alternative”
Where the line is
This is real medicine and real labs, not supplements in place of evidence. It uses more testing than a rushed visit allows — not less rigor.
In their own words
What patients say before they find root-cause care
“Every test comes back normal and I still feel awful.”
“I have been passed between four specialists.”
“Each doctor treats one part and no one looks at all of it.”
“I was handed a prescription in nine minutes.”
“My gut, my energy, and my mood all went wrong together.”
“I want to know why, not just take something for it.”
“I have autoimmune symptoms nobody can explain.”
“I would rather fix the cause than manage it forever.”
Every one of these is measurable. None of them is something you have to live with because someone called it normal.
Drawn at our in-office lab · Walk-in lab draws Mon–Thu 7:30–2, no appointment needed
What we measure
Sixty-plus biomarkers, read as one system
A functional panel is wider than a standard one on purpose — hormones, full thyroid, insulin and metabolic markers, inflammation, and nutrient status, drawn in our own office. The width matters less than the reading, though: these systems pull on each other constantly, so a thyroid result only means something next to your insulin, your cortisol, and your inflammatory markers. That is the part a fifteen-minute visit cannot do.
Full thyroid panel with antibodies
Fasting insulin & HbA1c
Inflammatory markers
Complete hormone panel
Cortisol
Vitamin D & B12
Full metabolic & lipid panel
Iron & ferritin
The full panel — including testosterone for women.
Sixty-plus markers read against each other rather than one at a time. Women get testosterone measured too, which most panels never check.
A “normal” result is where we start looking, not where we stop.
Root-cause work exists because the single-marker version already failed. If every number came back unremarkable and you still feel unwell, that pattern is the thing worth reading.
How it works
Three steps to a root-cause answer.
Root-cause care only works if you understand your own results, so the hour is spent teaching you your labs — not delivering a verdict. You leave able to explain your own body.
Step 01
Get tested properly
Over sixty markers are available across seven categories, drawn in our office at your Total Health Assessment with no separate trip to an outside lab.
60+ markers available
Step 02
Get the whole picture explained
About ten days later you get a full hour with Teresa, reading your results as one connected system instead of a list of isolated values.
One full hour
Step 03
Treat the cause and recheck
One plan — which may combine hormone therapy, thyroid care, metabolic work, nutrition, and targeted supplementation — adjusted from follow-up labs.
This suits some situations far better than others, and it’s worth being honest about which. Candidacy comes from your history and what you’ve already ruled out — here is the shape of who it tends to fit.
Likely a fit if
You’ve felt unwell for a while, and standard visits keep ending in “your labs are normal.”
Your symptoms cross systems — energy, weight, mood, digestion, sleep — and no one has connected them.
You want the cause found, not another single-symptom prescription.
You’re willing to do a deeper panel and spend a full hour on what it shows.
Not the right starting point if
You have an acute or emergency problem — that needs urgent or specialist care now, not a root-cause workup.
You want a specific medication prescribed on demand without evaluation; that isn’t this.
You’re looking for supplements to replace medical treatment for a diagnosed condition.
A single specialist already has a clear answer that’s working — you may not need this at all.
Not sure it fits your situation? That’s the normal starting point — the Total Health Assessment and a full panel are where it gets decided.

Teresa is Fantastic!! So glad I was able to get in with her. She genuinely cares and is there to help with suggestions and a ton of knowledge. Ladies, get those levels checked correctly, because I’m certain our Commercial doctors are not going that far!!!

Common questions
Questions about functional and holistic medicine.
What is functional medicine?
It is an approach rather than a specialty: test widely, read the results as one connected system, and treat the underlying cause instead of managing symptoms one at a time. In practice that means a much deeper panel than a standard physical, a full hour to go through it, and a plan that addresses why you feel the way you do.
How is this different from seeing my primary care doctor?
Primary care is built to catch and manage disease, and it does that well — this is not a replacement for it. The difference is depth and time: over sixty markers instead of a basic panel, a full hour instead of fifteen minutes, and a reference range read against how you actually feel rather than against the outer edge of normal. Many of our patients keep their primary care physician and come here for this.
Is this holistic or naturopathic medicine?
It overlaps with both in philosophy — whole-person, root-cause, and prevention-minded — but this is medical care delivered by a licensed nurse practitioner in partnership with a board-certified physician. Teresa prescribes and orders labs, and plans are built on your bloodwork rather than on supplements alone.
What conditions do you address this way?
Most people arrive with hormone, thyroid, or metabolic symptoms — fatigue, weight that will not move, brain fog, poor sleep, low libido, or autoimmune symptoms nobody has explained. Because the panel is wide, the plan often addresses several of those at once, since they usually share a cause.
Do you take insurance?
No — this is a cash-pay practice, and that is what makes the model possible. Insurance will not pay for a sixty-marker panel or a full hour of provider time. Everything is priced openly: the Total Health Assessment is $299 and credits in full toward whichever program you and Teresa decide on.

Often connected to
One system, not separate problems.
These rarely show up alone. Teresa treats them together, in one plan, rather than as separate departments.
It all starts with the $299 Total Health Assessment — a full lab panel, a one-hour results review, and a plan built around you. The fee credits fully toward any program you start.
