Stetch's family was ethnically Ukrainian, and as a boy, Stetch played in ensembles at Ukrainian weddings and sang in community choirs. He studied reed instruments early on but concentrated on piano from his teenage years onward. After graduating from McGill University in 1991, he relocated to New York City. He most frequently performs solo or in a trio setting, often with longtime collaborators Sean Smith (bass) and Rodney Green (drums). His professional career has included performing and/or recording with Ed Jackson, Jan Jarczyk, Chris Kase, Rufus Reid, Akira Tana, Alain Trudel, Mark Turner, and Johannes Weidenmuller.
