Valeri was raised in a circus family, touring through many countries in Europe and Asia. He started juggling at the age of 9 with hoops and sticks. Together with his father Eduard Tkach he created all his stick-tricks, which are unique in the juggling world. In 2000 he created his Original Juggling act under the direction of Aleksej Bitkine, which he has been performing since all over the world. In 2004 he first showed his Samurai Act (director: A. Bitkine) at the European Youth Circus Festival in Wiesbaden (Germany). In 2009 Valeri created a new modern act with director choreographers Tatyana Kuznecova & Vitaliy Suslovec: Vertex. For this act, the music has been specially composed by Gennadiy Diakonov. Valeri has always been looking for new techniques and tricks to improve his act.
