Williamson oversees the high jump, multi events and throws and is now in his fourth season with the Wolf Pack. He made an immediate impact as a member of the coaching staff in his first season, coaching La Tijera Avery to All-American status after she won a WAC indoor high jump title. Under Williamson's tutelage she would go on to compete at the NCAA Indoor National Championships and receive 2nd Team All-American recognition after finishing in the top 16 in the Nation. Coach Williamson also coached two athletes, April Pate and Alexa Anderson, to All-Conference performances. He saw an additional three athletes improve their performances to advance to the NCAA Preliminary Round as Nicole Williams went on to compete in high jump, and Danielle Stallworth and Sarah Nichols advanced to compete in the javelin.
Williamson coached three student-athletes to all-conference honors during the 2013-14 indoor and outdoor track & field seasons. In 2013, Williamson's student-athletes would go on to break two school records and win two Mountain West Outdoor Titles with marks among the best in the history of the conference. La Tijera Avery would follow up her senior indoor season by winning the outdoor crown in the high jump, finishing with a Top-15 West Region Ranking, setting a school record, and earning a berth to the NCAA Preliminary Round. Kerri Simmons finished her junior season with a conference championship, a school record, and a berth to the NCAA First Round. Williamson also developed two freshmen, Nicole Wadden and Shannon Forman, into Nevada All-Time Top-Ten performers in the pentathlon, and also coached Kennedy Hall onto the Nevada All-Time Top-Ten list for the shot put.
Prior to Nevada, Williamson spent six years as the head cross country and track and field coach at Nicholls State University. During his time at Nicholls State he led the 2010 cross country team to its first ever regional ranking, and coached the 2011 indoor and outdoor track and field teams to their highest conference finishes in school history. He recruited and coached 62 school record holders, two NCAA Championship qualifiers, 11 Southland Conference Champions, and 23 All-Southland Conference performers. In addition to his teams' athletic success, the academic performance record rate jumped from 843 to 967 during his tenure.
Williamson began his coaching career as a volunteer coach for sprints and hurdles at the University of Iowa before being hired to take over sprints and hurdles at Emporia State University.
He earned a double-major bachelor's degree in health, leisure, and physical studies and psychology in May of 2002 from the University of Iowa, and earned his master's in education from Emporia State in May of 2005.
"We are very lucky to have Scott as a member of our staff," Head Coach Shantel Twiggs said, "He brings a wealth of knowledge and a passion for track and field to the Wolf Pack. He is amazing at developing talent, and when you look at his teams, everyone he has worked with has seen improvement."
