Medical student · Ann Arbor, Michigan

Understand the mind. Change the trajectory.

I’m Jack Hennessey, an MD student at the University of Michigan interested in holistic, preventive, and high-performance health: care that begins with what shaped a person, helps restore agency, and connects psychological change to lasting physical health.

About

Start with the person’s story. Work outward from there.

Symptoms matter, but they are not the whole explanation. I am drawn to a mind-first approach that asks how development, trauma, relationships, culture, and repeated adaptations shaped the person in front of us—and how insight can become greater agency, connection, and capacity to live well.

Preventive medicine follows from that work. When someone can understand their patterns and act with more freedom, sleep, exercise, nutrition, metabolic health, and long-term risk become part of the same clinical picture. I hope to build a rigorous, deeply human practice that works from mind to body and from root causes to durable change.

Path to medicine

I came to medicine by following a question from systems to people.

Systems taught me where health is distributed. Relationships taught me how healing happens.

Then

Before medical school, I imagined a life in urban policy. I studied how infrastructure, climate, socioeconomic inequality, and political choices shape who gets to live safely and well. That work taught me to see the forces surrounding a person—but it also left me wanting a relationship with the person at the center.

The turn

The shift toward medicine was gradual, then increasingly clear. Working alongside the Yavapai Apache Nation deepened my respect for ways of understanding health that do not separate an individual from family, place, and community. Patient narrative and clinical research made the next step concrete: I wanted to care for people directly.

Now

Medicine lets me carry a systems view into an interpersonal practice. I am drawn to the two-way nature of care—the possibility that helping another person change course also changes the clinician—and to protecting possibility before disease, disconnection, or despair closes it down.

Direction

A mind-first model of upstream care.

Inspired by Bruce Perry’s attention to experience and adaptation, Paul Conti’s focus on agency and generative drive, and Peter Attia’s long-horizon approach to healthspan.

01

Story

Understand what shaped the person.

Begin with development, relationships, culture, adversity, and the adaptations that once protected a person but may now keep them stuck.

02

Agency

Build the capacity to choose differently.

Use psychotherapy and rigorous psychiatric care to strengthen self-understanding, emotional flexibility, purpose, connection, and generative drive.

03

Physiology

Turn psychological progress into longer healthspan.

Connect the work of the mind to sleep, exercise, metabolic health, substance use, and the long-term protection of cognitive and physical function.

04

Innovation

Use new tools without surrendering judgment.

Explore measurement, responsible AI, and emerging interventions where they deepen clinical insight and relationship rather than substitute for either.

Movement · community · performance

Performance is lived, not abstract.

I am interested in health that expands what a person can do—with others and over time. Training, recovery, friendship, and the willingness to keep showing up belong inside the same view of health.

Let’s connect

Let’s talk about human health, psychiatry, or the future of care.
