The proof
Before you trust us with your family, look at how we actually work.
Helping self-led families build lives they do not need to recover from.
Success should not cost you your health, your home, or yourself.
The method
Three questions, in this order — every single case.
Most care stops at the first question and calls it a diagnosis. The reason families arrive here after years of normal results is that nobody asked the second and third.
01
Blood
Blood finds what is there.
A full functional panel — not the five markers that keep coming back "normal." We read it against your history and your family's pattern, in ranges built for function, not for disease thresholds.
- Comprehensive panel read in functional ranges
- Interpreted against your intake, timeline and symptoms
- Every out-of-pattern marker written up, not filed away
02
DNA
DNA explains whether it matters.
The same marker means different things in different people. Your genetics tell us which pathways are fragile under stress, which detox and methylation routes are slow, and which findings are noise for you specifically.
- Pathway-level read: detox, methylation, inflammation, hormones
- Separates the findings that matter for you from the ones that do not
- Written by Dr. Nicole, not generated from a template
03
IRT
Integrative Response Testing finds the fix.
Dr. Nick's method tests what your body actually responds to, and in what order. That is how a protocol stops being a stack of supplements and becomes a sequence with a start, a rotation and a re-evaluation.
- Tests the specific inputs your body responds to
- Everything starts day one, on a six-week therapy rotation
- Week 6 re-evaluation against the data, not against a calendar
Who reads your data
Two doctors. One family. No hand-offs.
Dr. Nicole Rivera
Co-founder · Clinical direction · Higher Self Architecture
Dr. Nicole reads every marker against your history, your intake and your family's pattern — then writes your root-cause reports herself: the story, the physical drivers, the mental and emotional drivers, and the action plan.
She takes every Private Concierge consultation personally. There is no coach layer between you and the person interpreting your data.
Dr. Nick Carruthers
Co-founder · Creator of IRT & the Biointegration Technique
Dr. Nick built Integrative Response Testing — the method that finds the exact input that neutralizes a stress on your biology — and works the nervous-system side so the biochemistry has somewhere to land.
Together they bring 18+ years of combined clinical experience in root-cause functional medicine, for adults, children and whole families.
Documented cases
Don't take our word for it. Read the cases.
Real members, with documentation, on our results page. Read them before you decide whether our thinking is worth a conversation.
Twelve years of severe psoriasis
Covered up for over a decade, cycling through topicals and biologics. Root-cause work cleared the skin — short sleeves, off medication, flare-free.
Stroke recovery beyond the plateau
Told the recovery window had closed. Full mobility restored, speech clear, living independently again.
Years of "your labs are normal"
Chronic fatigue with clean bloodwork every time. Energy and clarity back once the pattern under the numbers was read properly.
Case study · Full write-up
A POTS diagnosis that was never POTS.
A 23-year-old engineering student with every textbook POTS symptom, attributed to antiphospholipid syndrome and Nutcracker syndrome. The full walk-through shows the diagnostic blind spots and exactly what Phase 1 data extraction surfaced.
