Zeb Sion

Zeb Sion's first season at Stanford had spectacular results, with Valarie Allman improving her discus best by nearly 12 feet to become the No. 12 thrower in U.S. history at 212-3 (64.69m) and capturing third at the U.S. Championships to earn a World Championships berth.

It was the first time a Stanford athlete with eligibility left had made a U.S. Olympic or world championship team in 12 years. Eight of his throwers advanced to the NCAA West Prelims, with three going on to earn All-America honors.

Mackenzie Little repeated as Pac-12 champion in the javelin and placed a personal-best fourth at the NCAA Championships, and others such as Trevor Danielson, Charles Kerr, Tristen Newman, Michael Painter, Lena Giger, and Jenna Gray all recorded lifetime bests while all climbing the Stanford all-time top-10 lists.

In 2017, Allman broke the school record four times in the weight throw, Newman became Stanford's first 60-foot shot putter in 22 years, and Danielson, who hadn't even competed in three years, improved his javelin best by 17 feet and qualified for the U.S. Championships.

Sion was named Stanford track and field assistant coach for the throws on Aug. 1, 2016. Sion has a strong background of developing elite student-athletes who are committed to success at the highest level both academically and athletically.

Sion arrived from Wake Forest, where he coached for five seasons, directing athletes to three Atlantic Coast Conference titles, four All-America performances, 14 NCAA East Prelims appearances, and 19 All-ACC honors. He's had an athlete compete at the 2012 and 2016 Olympic Trials as well as 2013, 2014, 2015, and 2017 U.S. Championships. He's also coached two U.S. junior champions.
