She completed degrees in Music and Music Education at Memorial University of Newfoundland, with a major in violin, and a Master's degree in choral conducting at the University of Maine. She has studied conducting under artists such as Wayne Riddell, Robert Cooper, James Croft, John Haberlen and Dennis Cox.
