Building
My first company was a lawn care operation I ran out of a sedan in Madison, Wisconsin. It grew past 100 clients before I finished high school — and it taught me everything that still matters.
Brand
The supplement industry has a trust problem. Here is why I decided to build a premium supplement brand anyway — and the standard it will be held to.
Performance
Motivation expires. Systems don’t. The operating structure I use to keep training, building, and shipping when I don’t feel like it.
