Jon Sioredas  |  Head Coach

Jon Sioredas begins his second season as head wrestling coach at Cal Poly. "I am honored and excited to lead a program with such rich tradition," Sioredas said. "I would especially like to thank Don Oberhelman and the Cal Poly Athletic Department for giving me this opportunity.

"Our expectations at Cal Poly are simple: to graduate with a meaningful degree, have a reputation of excellence on campus and in the community, and to produce NCAA All-Americans and national champions," Sioredas added.

Sioredas (suh-REE-duss) brings to Cal Poly an extensive background of collegiate coaching experience and was also an NCAA Division I All-American at the University of Tennessee at Chattanooga.

In his first year at the helm at Cal Poly, the Mustangs won more dual meets than in the previous five years, including wins over Indiana and West Virginia. The program also received its first team trophy at the Reno Tournament of Champions in 10 years. They qualified a pair of grapplers to the NCAA Championships in St. Louis, where Colt Shorts knocked off the No. 6-ranked wrestler in the country.

The Mustangs also excelled in the classroom. The team GPA is at a four-year high and the program received a public recognition award from the NCAA for being in the top 10 percent in the country with its Academic Progress Rate (APR). APR is a timely assessment of academic success at colleges and universities that is used to hold institutions accountable for the academic progress of their student-athletes.

Before Cal Poly, Sioredas spent two seasons as the head wrestling coach at Grand Canyon in Phoenix, Ariz. He was brought to GCU to guide the program through the transition from Division II to Division I. During this process, Sioredas helped build the depth across all weights to the standards of a Division I championship program by signing a nationally recognized recruiting class and three top-100 recruits. He was also able to pick up dual meet victories over Division I programs and place three All-Americans at the National Collegiate Open with his predominantly freshmen team.

Sioredas was an assistant coach at Chattanooga for two seasons. UTC finished the 2013-14 dual season ranked in the national top 25, at one point ranking as high as No. 19. The Mocs also captured the regular-season conference title, the conference tournament title, and qualified five for the NCAA tournament in Oklahoma City, with two seeded in the top 10.

Prior to his two seasons in Chattanooga, Sioredas spent six seasons as an assistant coach at Old Dominion. He helped guide the Monarchs to the top 25 in dual meet rankings four of his six years, with four All-Americans and an NCAA finalist. ODU also had 10 NWCA All-Academic honors, as well as being named top 10 in the nation in grade-point average during his tenure.

During his 11 years of coaching -- three as a head coach and eight as an assistant -- Sioredas has coached five top-25 teams, one NCAA Division I national finalist, four NCAA All-Americans, 40 national qualifiers, 12 Academic All-Americans and helped with six top-20 recruiting classes.

An All-American while competing at Chattanooga, Sioredas finished fifth in the 165-pound weight class in the 2005 NCAA Division I Championships. He was a two-time Southern Conference Champion and 2005 SoCon Wrestler of the Year and Tournament MVP.

Sioredas, recently inducted into the Tennessee at Chattanooga Athletics Hall of Fame, graduated from UTC in 2005 with a degree in sociology and anthropology. He earned his master's degree in business administration from Nova Southeastern University in Davie, Florida, in 2009.

A native of Chesapeake, VA, and a 2000 Great Bridge High School graduate, Sioredas was a Virginia state champion, All-American and national champion. He amassed a 181-13 career prep record, becoming the fourth winningest wrestler in Virginia high school history.

Sioredas and his wife, Michele, reside in San Luis Obispo with their son, Braden.


Todd Schavrien  |  Head Assistant Coach / Recruiting Coordinator

Todd Schavrien, an all-American wrestler at Missouri, was hired in June 2016 as head assistant coach and recruiting coordinator at Cal Poly.

Schavrien has served coaching stints at Appalachian State, Missouri, and Drexel. He was the head assistant at Appalachian Statefor the 2015-16 season and helped guide the Mountaineers into the Top 25, being ranked as high as No. 18 in the country.

He also coached at Drexel University after a successful wrestling career at Missouri.

Schavrien has coached two NCAA National Champions, 12 All-Americans and three of his teams finished in the Top 15 at the NCAA Championship. He was also instrumental in recruiting three top-10 recruiting classes.

A three-time NCAA qualifier himself, Schavrien capped his wrestling career with the Tigers by winning the Big 12 Championship and placing sixth in the country, earning All-America honors at 141 pounds, in 2011. Schavrien finished his career with an 86-44 record in three years with Mizzou after spending his first two seasons at Arizona State.

He served as Mizzou's team captain during the 2010-11 campaign and won the team's Hap Whitney Coach's Award at the end of that season. The award is given to the wrestler who displays dedication, commitment, sacrifice and selflessness to the team on a consistent basis.

Schavrien, a product of powerhouse Poway High School in San Diego County, was a 2006 California high school state champion and a two-time prep All-American. He also captured an FILA Junior National Championship at 60kg in 2007.

Schavrien earned his bachelor's degree in interdisciplinary studies from Missouri in 2011 and a master's degree in business administration from William Woods University in 2016.

"Coach Schavrien has been an integral part of one of the best-run programs in the country at the University of Missouri as both a student-athlete and a coach," said Sioredas. "He also brings coaching experience at the mid-major level, having spent time at App State and Drexel."
