About this gym
15th Round Boxing was founded in 2015 in Glendale, Los Angeles by brothers George and Evangelos Giovanis, who trained at Rhode Island Boxing and St. Pete Boxing Club before becoming coaches. After expanding to a second LA-area location in 2018, the brothers relocated the business to Sioux Falls, South Dakota, opening the current gym on March 1, 2021. The gym offers kids and adult boxing classes, open gym access, sparring sessions, and private one-on-one training, and the owners also run 15th Round Promotions, hosting professional boxing events.
