§ 01 · What I treat
A broad practice. One thesis:
find the upstream cause
before it becomes the next diagnosis.
Most of my clients arrive with three or four conditions a different specialist could each explain. My job is to find the upstream pattern that ties them together — and treat it before it becomes the next diagnosis.
01
Gut & Microbiome
IBS, IBD, SIBO, candida, dysbiosis, leaky gut — the foundation of nearly everything else.
Stool, organic acids, breath testing
02
Women's Hormones
PMS, painful or missing periods, PCOS, endometriosis, fibroids, thyroid, adrenals.
DUTCH, full thyroid, cycle mapping
03
Perimenopause & Metabolic
Sleep collapse, brain fog, weight changes, anxiety, insulin resistance — the 40s reset.
Reverse-Age Method program available
04
Fertility & Family
Sub-fertility, IVF support, preconception, post-partum, and pediatric integrative care.

§ 02 · How we work
Three acts. One person.
Your case, in full.
I.
Case review
A deep-dive intake — symptoms, history, prior workups, lifestyle. The interview no one has done before.
II.
Targeted testing
Only what's clinically warranted. DUTCH, stool, organic acids, full thyroid — wherever the story leads.
III.
Protocol & integration
A staged, sequenced plan. Supplements, lifestyle, behavior change — coached and adjusted in real time.
