For Medical Groups • Hospital Systems • High-Performance Organizations

Your team cannot perform at their best
if their nervous systems haven’t been prepared.

PRELOΔD is a 90-day neurobiological preparation program grounded in Karl Friston’s predictive processing framework, validated clinical instruments, and HRV biofeedback. Built by a practicing cardiothoracic anesthesiologist.

The Problem

High-performance environments demand regulated nervous systems.
Most training programs don’t address this.

Surgical teams, executives, first responders, and high-stakes professionals are trained in technical skills. Almost none receive training in the neurobiological preparation that determines whether those skills deploy correctly under pressure.

🧠

Predictive Processing

PRELOΔD trains the brain’s prediction systems before high-stakes moments arrive — not after the stress response has already fired.

💓

HRV as Daily Readiness

Heart Rate Variability is the most sensitive daily measure of nervous system state. The program treats it as a morning dashboard, not an afterthought.

📊

Outcome Measurement

GAD-7, PHQ-9, PSS-10, and PERMA assessments built in. Your organization can track measurable changes in anxiety, reactivity, and performance over time.

💞

Family & Relationship Layer

Performance doesn’t stop at the hospital door. The program explicitly addresses how nervous system state affects the people who matter most.

🌱

90-Day Protocol + Lifetime Practice

A defined masterclass arc with a clear completion milestone, followed by adaptive maintenance mode for ongoing practitioners.

Faith & Values Integration

Optional multi-faith spiritual layer including LDS, Christian, Buddhist, Jewish, Islamic, Stoic, and secular frameworks. The program meets each person where they are.

The Evidence Base

Not wellness content.
Applied neuroscience.

Every tool in PRELOΔD maps to a specific mechanism in the literature. The program draws on Friston, Sapolsky, Porges, Lally, Oettingen, and a curated set of landmark studies on stress, habit, and performance.

5.5s
Inhale/exhale ratio for maximum HRV coherence. Shifts ANS to parasympathetic within 2 minutes (Lehrer & Gevirtz 2014)
66
Median days for a behavior to become automatic (Lally et al. 2010, UCL)
Goal achievement rate with WOOP vs. positive thinking alone (Oettingen, 94-study meta-analysis)
40%
Reduction in cortisol carryover between high-stakes encounters with brief transition protocols (Abelson et al. 2014)

Our Founder

Built by someone who had to solve this for himself first.

“You are not the problem. Your preparation is.”

Christopher D.D. Larson, DO is a practicing cardiothoracic anesthesiologist who spent years in one of medicine’s highest-stakes environments before realizing that the critical variable wasn’t skill — it was the state of the nervous system that deployed those skills.

PRELOΔD is the program he built from the ground up, drawing on Karl Friston’s predictive processing framework, validated clinical instruments, and his own experience as a husband, father, and physician navigating high-stakes moments daily.

The book PRELOΔD: Prepare Your Neurobiology Before the Moment Arrives is the companion to the 90-day program.
