Song arrives in Des Moines after one year as an assistant coach at West Virginia University. In Morgantown, Song was part of an historic 2023-24 season as he helped guide the Mountaineers to a 15-13 overall record, their first winning season since joining the Big 12, and an appearance in the UTR Sports 2024 NIT Championship. WVU's postseason berth marked its first national tournament appearance in program history and included a 4-2 victory over Pacific for the team's first-ever postseason win. The Mountaineers were 11-1 through their first dozen matches last year, their best 12-match start since the 1986 season. The 15 total victories were most in program history since 2010 and the team also set a Mountaineers record for most Big 12 Conference wins in a season. Song was an essential piece of the WVU tennis puzzle as he had major impact on the Mountaineers' player development and recruiting.
Prior to his time at West Virginia, Song was an assistant coach at Fresno State University in Fresno, Calif. from 2021-23. He helped lead those Bulldogs to a 20-4 mark in the 2021-22 campaign and a combined 21-9 record in conference play over three seasons. During his Fresno State tenure, Song had a hand in the Bulldogs' 2022 Mountain West Conference regular season championship, when they went 10-0 in league play to clinch their first in school history, while instructing three MWC Players of the Year, a top-45 doubles team, and a trip to the 2023 NCAA Tournament. FSU enjoyed 10-straight weeks in the Top 75 of the ITA Team Rankings and reached as high as 51st in the country.
Before heading to Fresno, Song had volunteer coaching roles with the Wake Forest University men's team and University of Iowa women's program. During his time in Iowa City, Song and the Hawkeyes pulled off a top-50 upset. Prior to serving on the Hawkeyes' coaching staff, Calvin was an assistant tennis professional from 2016-20. He is a United States Professional Tennis Association (USPTA) elite pro-certified coach and was named 2020 USPTA Missouri Valley Iowa Pro of the Year.
A native of Ames, Iowa, Song graduated from Iowa State in 2016 after earning a Bachelor of Science in Marketing.
