Maria Kozlovskaya and Alexander Yumashev are Dominican bachata instructors and promoters.

Maria has more than 25 years of dance experience and over 15 years of dance teaching. She has been working in various dance styles from classical dance to urban club dancing. In 2008 together with Alexander, she got into Latin American dances, such as salsa, bachata and merengue. This passion brought them to the Dominican Republic in 2012. They fall in love with this country and stayed there for a long time to explore bachata. Later on they formed their own vision of teaching bachata and started to organise regular BailaMar Bachata Camps in the Dominican Republic. In 2014 they came back to Russia and started to spread traditional bachata there teaching regular and intensive courses for students of all levels and instructors, teaching at many festivals around the world and since 2016 organising authentic bachata festival Dominican Flow Festival in Moscow. In 2018 they moved to Ireland and later on opened BailaMar Academy in Dublin.
