Sergii Fesenko Coaching Staff

Assistant Age Group Coach

Sergey moved to Florida from Ukraine, where he was a head coach of a public swimming school. In less than five years between 2014-2019, Sergey created a swimming program and raised the level of the team to the national youth championship. His swimmers have repeatedly won National championships in 2018-2019.

Sergey has coaching history with “Ras Tanura Aramco” Saudi Arabia in 2013 and 2015. Twice in those seasons, swimmers of various age groups completed the NQT, the USA Standard to participate in the national championship and became KSA champions and medalists.

From 2000 to 2012, Fesenko was the head coach of the Ukrainian national swimming team and was responsible for the scientific and methodological support for swimmers. Comprehensive scientific training programs for the Ukrainian National Team at the Olympic Games 2000, 2004, 2008, 2012 have been repeatedly recognized as one of the most meaningful and achievable.

From 1992 to 1999 Fesenko was a coach and consultant for the Ukrainian National Team Age Group division, specifically for endurance and IM swimming.

Fesenko got his first international coaching experience while working in China in Hubei province with a local swimming team in 1990-1992. Fesenko was invited to China as an exchange program between the Universities of Kiev, where Fesenko headed the Department of Swimming and the province of Hubei.

Later, with his help, Liu Li Ming won medals at the World Championship and the Olympic Games at 200m butterfly.
