Who this is for

You're the one everyone leans on.

The team and the family both rest on you. You carry it well, and there's nowhere to put it down.

You track your HRV because you intend to be healthy and sharp for a long time. You've made changes, and the number moved for a while. Then it settled.

On the mornings it dips, you usually know why before you open the app. It's the conversation you replayed at 2am, or the decision you've been holding alone.

The HRV Mastermind is for founders and executives at exactly that point. You've done what the longevity playbook asks. What's left is underneath it.

The deeper work

The program running underneath

Much of what drives your HRV is the program running your life.

It was written early, for a good reason. It kept you safe and it built everything you have. It also decides how you respond when a deal wobbles, or when someone you love is disappointed in you, before you've had the chance to choose.

You've probably seen it already. Years of therapy, coaching or your own reflection may have shown you the pattern. Here you do something different with it. You name it out loud, in your own words, among people who know what it costs to run one. You bring agency to it. It stops running you, and you choose when to run it. The next time a deal wobbles, you see the program start, and the choice is yours.

I call it your Master Program.

Six weeks, four pillars

What we work on

01

Master Program

You name the program that's been running you and bring agency to it. By the end of the six weeks you've chosen the one you live from, and a wobbling deal or someone's disappointment no longer decides for you.

02

HRV Literacy

The course gave you the language. Here you use it, reading your own numbers against what's actually happening in your life.

03

Emotional Athlete Training

You've trained your body for years. This is the same discipline, applied to your nervous system. The practice gives you clarity when the pressure actually lands.

04

Devotional Practice

A daily practice built around you and your data. It can be as little as five minutes, and it's yours to keep after the six weeks end.

A few things you might be wondering

Got Questions?

How is this different from The HRV Practice course?

The course teaches you the language of your HRV. The mastermind is where you use it, live, with me and eleven other founders and executives, on the program that's driving your numbers. The course is included and comes first.

When do we meet?

Six Tuesdays at 7pm ET / 4pm PT, sixty minutes each: November 17 and 24, December 1, 8, 15 and 22. Your private hour with me happens the week of November 10. November 24 falls in Thanksgiving week, and that session is recorded like every other.

What's the time commitment?

One hour each Tuesday for six weeks, one private hour with me before we begin, and a daily practice that can be as little as five minutes. Before the first Tuesday you complete the course, which is about two hours of content.

What if I can't make a session live?

Live attendance is the commitment, because the room depends on the twelve people in it. Every session is recorded for the weeks life interrupts, and each recording stays available for 24 hours.

Do I have to finish the course first?

Yes. Your enrollment includes The HRV Practice. Its five modules release four days apart, so start the day you join and finish before our first Tuesday. That way everyone arrives fluent.

What happens in the private hour?

It's sixty minutes, one to one, the week of November 10. We find the program you'll work with over the six weeks, and I get to know you well enough to place you in the right trio.

What is a trio?

Twelve people in four groups of three. I choose the trios after the private calls. Your trio is the two people who hold your practice with you during the six weeks, and who you keep going with afterward.

Is what I share confidential?

Yes. What's said in the room stays in the room. Every member agrees to that before the first session.

Who is this for?

Founders and executives who carry a lot, already pay attention to their health, and sense that what's left to change is underneath the habits. If you track your HRV and it has stopped moving, you're in the right place.

Who is this not for?

Anyone looking for a shortcut or a number that climbs fast. This work asks for presence and honesty over six weeks. The HRV Mastermind is coaching and education. It is not therapy or medical care, and it does not replace either.

Do I need a wearable?

A wearable that tracks HRV is recommended and not required. Part of the work is reading your own numbers, so a device helps. If you don't track, you work from felt sense, and the course has a path built for that.

Will this raise my HRV?

Many people watch their baseline climb over time, and I will never promise you a number. HRV is your own language. When you change your relationship to stress and live closer to what matters to you, your body tends to follow.

I already own The HRV Practice. Do I pay for it again?

No. Write to us before you enroll and we'll credit what you paid toward your seat.

What happens after the six weeks?

You leave with a daily practice you chose and a written plan your trio made together for how you keep going. You keep lifetime access to the course and your resources.

What's your guarantee?

Your enrollment is protected by my 14-day Resonance Guarantee. Take 14 days from the day you join to feel whether it resonates. If it doesn't, email me and I'll honor a full refund.

Twelve seats. Enrollment closes October 31, or when the seats fill.
