This variety and experience has led to a lifelong interest and passion in the research and practice of voice science and vocal techniques. In 1993 Mary founded the post-graduate Musical Theatre course at the Academy – the first of its kind in a music conservatoire. She combined teaching at the Academy with a flourishing private singing teaching practice. She co-organised and presented two cutting-edge voice conferences in conjunction with British Voice Association at the Academy: From Rent to My Fair Lady and Rock Pop and Noise. She was also involved in planning and presenting at the Pan European Voice Conference in 2005, and she also presented a conference on contemporary sound in 2007. Mary has been a board member and closely involved with The British Voice Association for 30 years.
Mary was Head of Musical Theatre at the Academy from 1993 to 2012.
