South Dakota State athletic director Justin Sell and head wrestling coach Chris Bono announced the additions of Israel Silva and Andrew Sorenson as assistant coaches.

Silva served as an assistant coach at the Northwest Wrestling Regional Training Center in Corvallis, Ore., for the past three years. The NWRTC is an Olympic-level regional training center that provides services for senior-level athletes to achieve national and international success. The majority of his time was spent with student-athletes at Oregon State University.

Prior to his time at the NWRTC, Silva was a volunteer assistant under Bono at the University of Tennessee at Chattanooga for three seasons. A two-year starter for the Mocs, Silva earned a degree in sociology. He claimed the Southern Conference heavyweight title as a senior and was part of the Mocs' SoCon team championship in 2006.

Silva put together an impressive post-collegiate career on the international wrestling stage, as well. He is a four-time World Team Member for Mexico, three-time Freestyle Pan American medalist and 2012 Olympic alternate over seven years of international experience.

Before wrestling at UTC, Silva was a two-time Junior College All-American at North Idaho College. He placed second at the national tournament his sophomore year and was third as a freshman. Silva led the team to the Junior College National Championship in 2002.

"Having coached and worked with Israel, he brings a great deal of work ethic and knowledge to SDSU," Bono said. "His time at Oregon State and the Northwest Regional Training Center has helped him gain the experience to help us take this program to the next level. I am extremely fired up that Israel will be a part of the staff."

A native of Marysville, Wash., Silva was a four-time state qualifier at Pilchuck High School. He captured the state title his junior season, finished as the state runner-up his senior year and placed sixth as a sophomore.

Sorenson, a two-time national qualifier for Iowa State, finished his career with a 93-31 overall record, including a 42-9 mark in dual meets. He was a two-time Big 12 Conference placewinner, taking third in 2010 and second in 2012.

He also earned numerous athletic and academic honors in his time at ISU including: Team Captain, Total Commitment Award, Outstanding Wrestler Award, Dr. Wise Burroughs Leadership Award and the Iowa State University Academic Award.

Sorenson also spent time as a volunteer strength and conditioning coach at his alma mater during the past season. He trained NBA prospect Royce White, along with Olympic sport student-athletes and many Cyclone sports teams.

"I am excited that Andrew has agreed to become part of the Jackrabbit family," Bono said. "He is one of the hardest workers I have ever coached in my career and will bring passion and intensity to our program. He is fresh out of college and will be someone who can get on the mat every day with our student-athletes. Andrew is a perfect fit for Brookings and SDSU Wrestling."

A native of Woden, Iowa, Sorenson won a Class 2A state title at Woden-Crystal Lake-Titonka High School. He placed in two other seasons, as well, and finished his career with a 155-10 prep record.

Sorenson graduated from ISU with a degree in kinesiology-health fitness management and is working towards a Master's degree in educational leadership and policy studies.
