Rex received a Master’s in Sport Management from Central Michigan University, a BA in English from UC San Diego, and a Denver Business Journal 40 Under 40 award.

RKG Sports works as an extension of your team. We show what needs to be fixed, then build the sponsorship infrastructure, price the assets, create the packages, and go sell them to brands who elevate the experience for your families.
