The Problem

You've been living
in your head.

Men living in their heads. Successful on paper, disconnected underneath. You can have the money, the career, the relationship — and still feel the gap between who you are and who you're meant to be.

That gap isn't a discipline problem. It's uncleared trauma and old stories blocking the man you actually are.

What's Actually in the Way

This isn't a discipline problem.
It's a depth problem.

The Root

You were never taught how to feel — only how to perform. What looks like weakness is disconnection: from your heart, from your brothers, from something worth serving.

The Trap

More achievement won't fill it. More control won't fix it. Real power doesn't come from armor — it comes from an open heart and a clear purpose.

The Way Through

When a man clears his trauma, faces his shadow and truth, and steps into service — everything changes. How he loves. How he leads. His role in the world.

The Container

Sol Brotherhood is not a course.
It's a forge.

Eight weeks. Live sessions, private 1:1 calls with David, two full breathwork journeys, somatic practice, and brothers who hold you to your full potential.

The man who walks out is not the man who walked in — in body, in identity, in how he loves and leads.

The Journey

Eight weeks. Eight shifts.
One man on the other side.

Each week moves all three levels — what you think, what you feel, how you act. Anything less is information, not transformation.

01
Week One
Arrival
Where are you, really? We begin with radical honesty.
02
Week Two
The Mirror
Your relationships reveal your patterns. We look.
03
Week Three
The Shadow
What you won't face is running you. We go there.
04
Week Four
The Body
First of two 60-min breathwork journeys. The most powerful sessions of the program.
05
Week Five
The Rewrite
Your story runs you. This week, you rewrite it at the root.
06
Week Six
The Vision
Purpose, mapped to action. A man without direction drifts.
07
Week Seven
Brotherhood
To be truly seen by other men. This is the initiation.
08
Week Eight
The Vow
You speak it aloud. Witnessed. Sealed.

What You're Getting

Everything you need.
Nothing you don't.

8 Weekly Group Sessions — 90 Min

Live, held, demanding. A container, not a lecture. You will be seen, challenged, and moved every week.

5 Private 1:1 Calls With David

One to orient you before we begin. Four throughout to track, integrate, and lock in what's shifting.

2 Full 60-Min Sol Breathwork Journeys

Two dedicated breathwork sessions built into the program — the most powerful hours of the container for most men.

Men's Circle Containers

Deep, witnessed conversation — the kind most men have never had.

Telegram Brotherhood Channel

The work doesn't stop between sessions. Brothers available all week.

Weekly Integration Practices

Journaling, somatic work, and daily anchors that embed each week's shift into your life.

Accountability Brother Pairing

One man. Weekly check-ins. A bond that outlasts the program.

Lifetime Brotherhood Access

You don't graduate into isolation. The brotherhood is yours to keep.

What You Walk Away With

Not motivation.
A different man.

A Clear Purpose

A one-sentence mission you can stand behind, mapped to the actions you take this week. Limiting beliefs cleared at the root.

Your Heart, Open

You feel without being swept away. You stay present under pressure. Your body becomes home — not a place you escape.

Trauma Released

Through breathwork, somatic work, and brotherhood — what's been in the way finally moves. The armor comes off.

Your Full Power, Integrated

Masculine and feminine, light and dark, working together. You lead from wholeness instead of armor.

Brotherhood That Holds You

Men who've seen you without the mask and call you forward when you drift.

Love, Transformed

How you show up for the people in your life shifts completely. Presence over performance. She'll feel it.

From the Men

They showed up. They did the work.
Here's what they found.

"This wasn't therapy and it wasn't a seminar. It was something I didn't know I needed — being truly seen by men who weren't going to let me hide. That changes something at the root."

— Craig

"The breathwork session in week 4 cracked open something I had been carrying for years. I'd spent years in my head trying to process it. One session and it moved. That alone was worth more than the investment."

— Xander

"I came in thinking I had my life together. I left knowing who I actually am. Those are two completely different things — and I didn't know the difference until I experienced it."

— Alexander

Your Guide

David Castillo

David's mission is to elevate humanity and the Earth. His work sits at the intersection of inner transformation and real-world systems change — spanning clean water access, renewable energy, policy, social impact, and storytelling.

He is the founder of Colibri Collective, a collective philanthropy platform focused on social and environmental impact. The first project launching this fall will provide clean water access to 13,000 people in rural Nicaragua.

Since 2022, David has dedicated himself to trauma-informed breathwork, nervous system healing, and purpose-driven leadership — guiding more than 200 people through breathwork and heart coherence practices that have been foundational to his own healing journey.

David also brings more than 15 years of experience at the forefront of climate technology — as an entrepreneur, strategist, and leader at top climate startups across energy storage, solar, clean energy software, and ESG investment. He holds a B.S. in Conservation and Resource Studies from UC Berkeley.

At the center of everything he creates is one mission: to help people reconnect — to themselves, to each other, and to planet Earth.

Work With David — Founding Rate

Is This You?

Built for one kind of man.

You want to show up fully for your family, your work, and the world
You can commit to the full 8 weeks — sessions, practice, and brotherhood between

Not for you if —

× Making more money is your only goal — this work goes far deeper than that
× You want to consume content without entering the container
× You need clinical mental health support right now — this is transformation, not therapy

Common Questions

What men ask before they commit.

No. This is transformation — somatic work, breathwork, and brotherhood. No doctrine, no dogma. If you need clinical support right now, this isn't a substitute for it.

Sessions are recorded, but recordings aren't presence. The work happens in the room, in real time. Show up.

The 90-minute session plus 2–4 hours of integration — journaling, daily practice, and a check-in with your accountability brother.

Sessions on Zoom. Brotherhood on Telegram. Once your application is accepted, you'll get a full onboarding packet.
