Functional medicine & biomarker optimization

Real health starts at the root.

Your labs might say "normal." Your mitochondria disagree. Take the self-check below to see where to start — or skip straight to working with me directly.

Two ways to work with this

Choose your path

Both start in the same place — understanding what your body is actually telling you. Where you go from there depends on how hands-on you want me to be.

PATH 01 — SELF-DIRECTED

Learn to read your own labs

For people who want to understand their bloodwork, spot what a "normal" result can hide, and choose their own next steps.

PATH 02 — GUIDED JOURNEY

Work with me directly

Personalized analysis of your labs, a custom supplement stack built for you, and a retest to confirm it's working. Limited availability — this is hands-on work.

Retest to track real change

The Root Cause Self-Check

Rate how often each applies to you. This isn't a diagnosis — it's a starting point for what to look at next.

Energy & Mitochondria

Afternoon energy crashes, even with adequate sleep

Fatigue that doesn't improve with rest

Exercise recovery takes longer than it used to

Cognitive

Brain fog or trouble concentrating

Word-finding difficulty or mental fatigue by midday

Inflammation

Unexplained joint or muscle aches

Frequent colds/infections or slow healing

Puffiness or water retention without clear cause

Iron & Nutrient Status

Cold hands and feet, or feeling cold often

Hair thinning or shedding more than usual

Restless legs or cravings for ice/starch

Sleep & Recovery

Wake up unrefreshed despite 7+ hours of sleep

"Wired but tired" feeling at night

Stress Load

Feeling "tapped out" — low resilience to normal stress

Path 02 — Guided Journey

What working together looks like

This path is limited by design. It's one-to-one work, and I can only take on so many people at once. Here's what each 3-month cycle includes:

Intake and lab review. A short questionnaire, then we go through your Root 11 results together, including values that sit inside the standard range but outside the optimal range.

A written plan. Education-focused nutrition and supplement suggestions, in a sensible order, with the reasoning behind each.

Weekly check-in and a mid-cycle call. One short email from me each week, plus a call around week 6.

Retest review. At about 3 months we look at your new results and adjust the plan.

$495 for the first 3 months. $295 for a second 3 months after your retest review. Labs and supplements are separate, ordered through Fullscript.

Join the waitlist

Opening soon, to Missouri residents only. Joining the waitlist is free and no payment is taken. I'll email you when spots open. The Guided Journey is educational and nutritional support, not medical advice, and it does not diagnose or treat any condition.

How the pieces connect

Why one problem often becomes three

Your cells' systems overlap, so trouble in one place can feed trouble in the next. Tap each step to see what's happening and which labs offer a clue.

Labs and pages that offer a clue

A simplified model for education, not medical advice. Your body has built-in repair systems; this shows what can happen when they are overwhelmed. Overlapping pathways multiply, they don't just add.

Go deeper, one step at a time

Each step of the loop has its own short read, with the labs that offer a clue.

A "normal" result isn't always an optimal one
