Mark Bertrang: Founder & Visionary

I actually did the math. I have sat along someone and have listened to their story over ten thousand times in my office. This is how my life has been blessed. I am a listener. It’s an intimacy that very few will ever have the opportunity to experience.

When I was young and new in my career, I was told to talk about my knowledge, my credentials, my licenses and my connections to impress potential clients. That’s stupid. It’s not about me. It’s about you.

Here is how I would engage you during a conversation. You talk and I would listen and I ask questions.

If you’ve Googled me, you already know me; and since you already know me, why would I waste your time talking about myself. Instead, I’ll listen to you.

I would like your permission to join your journey. Our team is hired to make lives whole, to heal past mistakes and to dream toward the possibilities in your future. You already know what you need to do. Press the “Start Now” button at the top of this page. Let’s get going.
