About esynchro

esynchro is an educational company established in 2000 by Duke Zielinski and Carol Valles. We developed our first products more than 15 years ago and have been updating and adding  educational materials and merchandise ever since. Esynchro has been a sponsor and educational partner of USA Synchro for more than 10 years, providing financial support, educational materials, clinics, consultations, training plans, apparel, gifts and more. We have been the sponsor of the esynchro US National Age Group Championships for more than 10 years- the largest synchronized swimming competition in the world with more than 1,000 swimmers attending annually. In addition, we have been the title sponsor for two FINA Junior World Championships: 2001 in Seattle and 2010 in Indianapolis.  

After four years of waiting, esynchro again has new educational material. We have done much research and study over the last four years and are proud to be developing and producing new materials to help synchro swimmers and coaches around the world. In addition to new books, we are planning to start translating our information for more widespread application.
