The Connection Codes

The Blueprint & Tools for Creating the Relationships You Crave

If you love deeply, you hurt deeply. If you don't, it's much worse.Opening lines

Paperback and audiobook. Also published in German.

It is the language of your birth.

Humans are coded for relational connection with other humans. Often that coding has been short circuited and needs reactivating. However, we do not need to learn it, we need to relearn it. This is not a new language; it is the language of your birth.

The Connection Codes are the culmination of over 30 years of research, education and experience and draw from many centuries of insights and wisdom.

What you get is a vocabulary you can use out loud: eight core emotions, each with a message and a need, on one wheel you can put on the kitchen table and work through with the person sitting next to you.

“This is dedicated to everyone in pursuit of the deep connection that makes life worth living.”

I don't want to be vulnerable until I know you're safe, but I won't know you're safe until I'm vulnerable. So, someone has to take a risk.

I've never experienced something so practical yet deeply transformational. Every area of my life has been impacted for the better by the Connection Codes.

The Connection Codes have truly changed our lives — we use the tools every day! It has been absolutely beautiful and amazing to see how much stronger our connection with each other and our kids has become.

We've spent a small fortune on marriage and family counseling and have never made so much progress so quickly. So simple, implementable and powerful!

The Kohlers · Zurich Switzerland

I so appreciate that the connection code is taught from a psychological and scientific perspective, not just a blanketed, ultra-spiritualized and sensationalized sentiment.

Bethany · Chicago IL

Everyone needs the Connection Codes! It opens up a whole new world of intimacy and connection we never knew existed! We talk Connection Code with everyone now like it's a second language.

I have recently reunited with a sibling who hasn't communicated with me for decades. I am so grateful for this series — it is life-changing, and I thoroughly recommend it to everyone!

For years we struggled with our communication and emotions — we began to think it would never get easier. Then we learned the Connection Codes tools and they've changed our marriage, friendships and life.
