Sasha Alexeev was born in Leningrad (now St. Petersburg), Russia to a musically talented family. His musical education was started by his grandmother Anna Borisova, who supported him through all the years by buying him the first as well as later pianos.
His parents, Arkady and Eugenia Alexeev were also always encouraging him to explore the music world and paid for the piano lessons through his study years. Sasha is very grateful to his family for that. At the age of five he was accepted to the Vermishev School of music where he studied with some of the premiere music maestros in the Soviet Union. By the age of nine, Sasha had created his first compositions and was widely recognized as a prodigy in Leningrad.
After many years, Sasha was finally able to come to America and study piano at the prestigious California Institute of the Arts, working with such teachers as Leonid Hambro and Howard Richman. During that time he created several original compositions that won local and national acclaim. In addition, Sasha became skilled at the drums, viola, and he took extensive voice training.
He graduated with distinction. Around that time he also won the Seraton International Piano Competition as well as the American Music Festival competition.
