Our Founders



Rex was a 3-sport athlete at Linfield HS in Temecula, CA and played college baseball for both Loyola Marymount University and University of California, San Diego, where he graduated in 1992 with a Bachelor’s degree in English. Rex then attended Central Michigan University in Mount Pleasant, MI where he earned a Master’s Degree in Sports Management.

In 1995, Rex began coaching a competitive travel baseball team. When a majority of his players struggled to draw the attention of college coaches, Rex launched aggressive marketing plans for each prospect. He worked diligently for those who dreamed of maximizing their college opportunities through athletics. As Rex saw his players enjoy enormous success, he knew he had found his true passion.

Since 2003, Rex has educated tens of thousands of parents, athletes, coaches, guidance counselors, college planners and school administrators on the college athletic recruitment process. He is a 2008 recipient of the Denver Business Journal’s “Forty Under 40” award. He is an active member of the National College Advocacy Group (NCAG) and is recognized among the country’s leading authorities in college athletic recruiting.

Rex resides in Parker, Colorado with his wife Kristin and their two children, Reed and Olivia.


Rex Grayner



Zack was a standout linebacker at St. Francis HS in Los Altos, CA. When college coaches all but overlooked him, Zack’s dad launched an aggressive recruiting campaign. In the end, Dartmouth College came calling.

As a 4-year starter for The Big Green, Zack earned All-Ivy League honors three times and was named All-America as a senior. The Arizona Cardinals drafted Zack in the 6th round, and he enjoyed a 5-year NFL career before retiring in 2002.

Zack’s story of “overlooked HS prospect to NFL linebacker” gained national attention, and it compelled him to start a company to help prospective athletes avoid common recruiting pitfalls. It was here that he connected with Rex, and the rest, as they say, is history.

One of Zack’s closest friends was Pat Tillman, the former Arizona Cardinal who was tragically killed in combat in Afghanistan.

Zack resides in Scottsdale, Arizona with his wife, Eva, and their son, Channing.
