Katherine Bateson-Chandler, born in Great Britain, moved to New Jersey when she was 13. Starting at age 16, she worked for American dressage star Robert Dover for 16 years until his retirement, traveling with the horses to international competitions. Based in Wellington, Bateson-Chandler and her mount Alcazar, owned by Jane Forbes Clark, regularly compete at the Grand Prix level. Currently, Bateson-Chandler trains each summer in Europe with Olympian Carl Hester and gains international exposure competing abroad. In 2017, Bateson-Chandler and Alcazar won over the crowd and the judges with a sensational first-place performance in the CDI 4* Grand Prix Freestyle at the Adequan Global Dressage Festival. They went on to compete for the U.S. in the 2017 Uggerhalne, Denmark CDIO Nations Cup, and then helped Team USA claim the bronze at the 2017 Hickstead FEI CDIO3* Nations Cup. In 2018, Bateson-Chandler and Alcazar won the Grand Prix Special during AGDF Week 5 and placed third in the Grand Prix CDI4* during Week 10. Strong showings so far this season for Bateson-Chandler and Alcazar include second place in the FEI Grand Prix CDI5*, presented by CaptiveOne Advisors, during AGDF Week 5.
