Welcome to The Tracker

An Invitation to Follow Your Track

What does it mean to live well… not perform well, but live well?

What does it mean to do that in a body you’ve never fully understood, in a healthcare system that gives you fifteen minutes and calls it medicine, in a culture that has confused optimization with aliveness?

These questions have followed me my entire career, through Stanford, UCSF, and two years of clinical research fellowship learning how to read a study the way a mechanic reads an engine: not just what it says, but what it’s potentially hiding.

They’ve followed me into the backcountry, where I’ve led men through whiteouts at altitude and watched something fall away that no lab panel can measure. Into the circles of men I’ve sat with for years, watching high-performing, outwardly successful human beings discover, often for the first time, that the life they built has an interior that has been waiting for them. Into the exam room, where I’ve learned that a man’s lipid panel and his loneliness are not separate clinical problems.

What I’ve found, again and again: the men who are moving the fastest are often the ones following the wrong track.

The Problem With What You’ve Been Offered

You’ve been sold two things. Neither is complete.

The first is conventional medicine, which is rigorous, evidence-based, and organized almost entirely around disease management. Your annual physical is screening for catastrophe. It is not a map for how to live. Most of what determines your quality of life at 60, 70, 80 — your muscle mass, your cardiovascular architecture, your hormonal milieu, your capacity for connection — your doctor isn’t measuring, let alone discussing.

The second is the wellness-influencer complex, and it has never been louder or more dangerous. Peptides promoted by people who can’t interpret a pharmacokinetic curve let alone safety or effectiveness. Protocols built on mouse studies and affiliate links. The signal-to-noise ratio is tragic, and the cost isn’t just wasted money. It’s misdirected attention and hope in a finite life.

Neither lane is enough. Most medical voices give you data without meaning. Most wellness voices give you meaning without rigor. You deserve both in the same room, from someone trained to hold them together and prepared to walk the talk.

That is what this substack is.

What I Believe

I believe your biology is specific to you — not to a population mean, not to a guideline written for actuarial convenience, but to your genetics, your history, your body under load, your inflammatory response, your particular kind of stress and the unique way you’ve learned to carry it.

I believe that grip strength is a vital sign and resistance training is medicine. Your 30-year cardiovascular risk is a conversation worth having at 42, not 64. Your psycho-emotional architecture lies underneath your choices as patterns laid down early, running quietly in the background, and ultimately determining whether any of your protocols will hold.

And I believe, with equal conviction, that none of that is enough if the life you’re optimizing isn’t the one you want.

I’ve earned black belts in multiple disciplines, not because I needed credentials, but because martial arts taught me that the body is the first text — that how you move and react under pressure tells you everything about how you’re living. I’ve led men through heli-skiing expeditions in Alaska and couples’ retreats in the desert, not as a side project, but as the same work: taking people to the edge of the familiar until something honest shows up.

The men’s groups I run are called Masculinity, Measured. What happens in them can’t be fully described here. What I can tell you is that men who have won by every conventional measure begin to remember in those rooms. Dreams and aspirations quietly set aside years ago, traded for financial success and the appearance of arrival. Someone finally gave them permission to become whole.

That is the version of medicine I practice. Precise and human. Rigorous and alive.

Why The Tracker, Why Now

The gap I’m describing — between clinical rigor and the deeper questions that determine whether a man is inhabiting his life — has no owner. I’ve watched it go unaddressed for my entire career.

Not by bad actors. By a system that was never designed to hold it.

The annual physical can’t hold it. The wellness app can’t hold it. The self-help book can’t hold it. The longevity and wellness clinics can’t hold it. And the influencer with 800,000 followers and a peptide stack can’t hold it.

This substack is where that thinking lives. It is the written extension of my clinical practice, clinical research, and my couples’ and men’s group work — the place for what a 15-minute visit cannot contain.

What You’ll Find Here

Every week, I’ll bring the clinical rigor, the honest questions, and the human framework that high-performing men are not getting anywhere else.

Starting June 15th, three times a month — with occasional Substack Live conversations from my practice — I’ll open with a first series on peptides: what the evidence shows, what remains genuinely unknown, and how to navigate a space that is equal parts promising science and predatory noise. I’ll show you how to read a study. I’ll tell you what I use with patients and why. I’ll tell you where I am uncertain, because that’s what intellectual honesty looks like from a physician who isn’t selling anything.

Beyond that, expect:

— Essays on what the data says about how men age — and what you can do about it, specifically and precisely, starting now. Testosterone, cortisol, cardiovascular risk, body composition, grip strength, biological age.

— On male-pattern depression and the ways it disguises itself. On the labs your doctor isn’t running and why they matter.

— The harder questions alongside all of it. What are you numbing? Is the life you’re optimizing the one you want? What would it mean to follow your actual track rather than the one you inherited?

I’m not here to give you another protocol to manage. I’m here to help you see clearly including what’s happening in your body, what’s happening underneath it, and what to do about both.

A Different Kind of Voice

Healthcare has needed this for a long time.

We don’t need another guru or someone with a supplement line, or a public health official telling us what works at the population level, i.e., promulgating medicine for the average.

Someone writing to you… the specific man in the specific body with the specific life that is, in some essential way, uninhabited.

Someone trained to read the literature without being seduced by it, and trained by years of sitting with men at the edge of change to know that the literature is never the whole story.

Someone who’s spent 50 years studying martial arts, 30 years practicing yoga and meditation, and a lifetime as a seeker. Someone who runs his own N-of-1 experiments to figure out what works and what does not work in this moment, in this time, in this body.

That’s what I’m offering. I hope it’s what you’ve been waiting for.

I’ll see you June 15th.

With respect and a full heart —
