I am an extremely driven athlete, constantly looking for ways to improve my game both on and off the field. This includes not only soccer but nutrition, sleep, and all types of recovery. I have a large following where I played in college at Purdue University, and am working on gaining a large following here in my new home in Eindhoven!

After more than ten years and thousands of brand deals with athletes and creators at OpenSponsorship, here is how we think about it, and the framework we use with our clients.
