Entrepreneur. EOS Implementer. Recovering know-it-all.
Business is f'n hard.
I'm still figuring it out too.
I've had wins. I've done some dumb shit. I've hired the wrong people. I've chased the wrong opportunities. I've had businesses grow and businesses hurt. I'm still doing it every day.
Here are the things that have actually helped. If something I've learned can make your business or life a little easier, take it.

A few words from people I've worked with.
“The EOS model has helped our business 'get back to the fundamentals,' which, in turn, has prepared us to scale. It's been a great benefit to us.”
“Working with Calvin gave me a completely different perspective on my career and personal goals. He asked the right questions, challenged my thinking, and helped me turn ideas into a clear action plan. I left every session with more clarity and confidence about what I needed to do next.”
“I had the ambition, but I was struggling to stay consistent and focused. Calvin helped me break down what felt overwhelming into practical steps I could actually follow. His approach is direct, honest, and incredibly motivating. I've made more progress than I expected because I finally had someone holding me accountable.”
