Who We Are

Guided by decades of leadership at Stanford and Rutgers and inspired by personal experience, our team of medical and academic experts came together to create a science-backed path to real healing and resilience.

The Core Team

A mission-aligned team united by a shared belief: true healing happens when science, compassion, and collaboration meet. Together, they are redefining whatʼs possible, for health and life.

Our Story (Our Band)

Where It Started

How It Started

Kristin is a hospital executive who suddenly found herself on the other side of the system. After developing long COVID, she became the patient sheʼd spent her life serving. She saw twenty specialists, undertook countless scans—each one offering
expertise, but not integration.

Then a former colleague; a Stanford neurologist said something that changed everything: “Thereʼs too much happening for this to be random. The root cause might be your autonomic nervous system.”

That insight reframed her recovery and eventually, our company.

Mapping Recovery Like a System

Kristin began tracking her healing the same way elite hospitals improve outcomes; through systems thinking and daily calibration.

With help from her community and seven determined siblings, she built a research map for healing and applied a Daily Management System (DMS) to the biology of recovery itself.

Progress wasn’t linear, but within two weeks, she was walking and talking again.

Two Paths Converge

Meanwhile, Vicente who was then leading New Jerseyʼs statewide COVID-19 response, was running on adrenaline and duty. Years of high-stakes leadership had rewired his physiology.

When he reconnected with Kristin, they discovered they were studying the same problem from opposite ends: Kristin was applying systems to biology. Vicente was applying biology to systems.

Together, they began decoding what had gone wrong and what had gone right.

The Band

They call themselves a band—because healing, like music, happens through harmony.

Each member brings a different instrument:

Mike, a movement specialist trained in biomechanics, form and function teaches the body to speak safety through motion and how to understand your capacity.

Mariella, a certified coach and facilitator, brings emotional coherence, helping people translate insight into sustainable change.

Kristin & Vicente, the original architects, integrate systems design with neuroscience to make regulation measurable and repeatable.

Behind the band stands the Advisory Board, physicians, neuroscientists, and behavioral experts who help ensure that everything iCalibrate does is both compassionate and evidence-based.

What iCalibrate Stands For

What began as personal experimentation has become a living framework: A fusion of neuroscience, somatic medicine, and behavioral design that teaches the body to remember safety, capacity, and coherence.

Every practice, every live session, every protocol is guided by:

Lived experience and measurable biology
A world-class panel of experts
Core values of precision and empathy, structure and flow

We call it iCalibrate because thatʼs what it is—a system for tuning the instrument of your life. Not by fixing whatʼs broken, but by restoring whatʼs always been intelligent inside you.

This is iCalibrate. Science at the core. Humanity at the center. Progress in every step.

The Advisory Board

iCalibrate is setting a new standard: transformational outcomes, measurable progress, and an experience designed with the precision of medicine and the humanity of art.
