Master the science of hormones — and the clinical reasoning to use it

If you've ever sat in front of a confusing thyroid panel — or fumbled through a Cushing's work-up because you weren't sure what the overnight dexamethasone suppression test was actually testing — you already know the problem this school is designed to solve. Endocrinology has a reputation for being one of the hardest subspecialties to master, and I think that reputation is earned by the way it's usually taught, not by the subject itself.

Most learners encounter endocrinology as a taxonomy of diseases: memorize the causes of hypercalcemia, memorize the criteria for PCOS, memorize the insulin dose adjustment rules. And then they hit their first real patient — the one with fatigue, mild hyponatremia, and a blood pressure that won't respond to three antihypertensives — and the taxonomy doesn't help, because the patient didn't read the textbook. What helps in that room is mechanism. If you understand the renin-angiotensin-aldosterone system well enough to reconstruct it from first principles, primary hyperaldosteronism doesn't need to be memorized — it follows. That is what I want to give you.

This school is structured the way I believe endocrinology has to be learned: physiology first, always. Before we diagnose hypothyroidism, we trace the full thyroid hormone synthesis pathway, understand the deiodinase conversion of T4 to T3 in peripheral tissues, and establish precisely why TSH behaves as a log-linear amplifier of free T4 changes. Before we manage DKA, we work through insulin's role as a counter-regulatory gatekeeper of lipolysis and ketogenesis. Every pathology is introduced as a deviation from a physiological setpoint you already understand — which means you can reason through atypical presentations, not just recognize classic ones.

The clinical reasoning and emergencies module exists because mechanism has a deadline. Myxedema coma, thyroid storm, adrenal crisis — these are not conditions where you look up the diagnosis. You need a pre-built cognitive framework that activates under pressure, and that framework has to be anchored in the physiology or it won't hold. We build that framework deliberately, case by case, before the clock is running.

I built this school for the learner who is not satisfied with "just know this for the test." If you are willing to sit with a complex negative-feedback loop until it makes sense — to re-read a paragraph about GnRH pulsatility until the downstream consequences of PCOS click into place — this curriculum will reward that effort with a quality of understanding that will follow you through residency, fellowship, and practice. The invitation is open.
