Tiffany Victoria Efimov was born in Toronto, Canada, in 2005. She began dancing at the age of three at the Canadian Ballet Theatre under the direction of Nadia Veselova Tencer, a graduate of the prestigious Vaganova Ballet Academy. At the age of eleven, Tiffany began competing annually in the internationally acclaimed Youth America Grand Prix (YAGP), participating from 2017 to 2024. Throughout her competitive years, she earned numerous awards, including the Hope Award, the Youth Grand Prix Award, and several other top honours. Her performances at YAGP also earned her scholarships to elite summer intensives, including those at the Royal Winnipeg Ballet, Alberta Ballet, and American Ballet Theatre, where she was named a National Training Scholar for two consecutive years. In 2024, Tiffany relocated to the Netherlands to continue her training at the European School of Ballet. There, she refined her technique and broadened her artistic versatility, performing repertoire by renowned choreographers such as Goyo Montero, William Forsythe, David Dawson, and Jiří Kylián. Tiffany is thrilled to begin her professional career with the Wrocław Opera Ballet in the 2025/2026 season.
