Deborah’s conducting career began many years ago when she met the friends who now make up The Imperial Male Voice Choir. Under her baton IMVC won their first competition in 1980 and are still winning prizes. In 2016, Deborah was inspired to form a complementary women's voice group, Gloriana, hand picking singers from among the choirs she worked with. This produced an ensemble which has attained a consistently high standard and won many plaudits and commissions from contemporary composers. Deborah brought the choirs together in 2018 for an exciting concert – Men from Mars, Women from Venus, Music from Heaven! – that highlighted each group’s distinctive sound.

Imperial Male Voice Choir was formed by students at Imperial College of Science & Technology in the late 1970s. Deborah became their conductor early on and the first concert was given in London in 1978. Just over 40 years later, in 2019 they won the International competition held in Poole, Dorset.

For many years the choir rehearsed in a room over a Westminster pub! However as the choir has increasingly recruited new members from all over the Home Counties, a unique rehearsal structure has been devised that uses venues round the M25.They sing four charity concerts a year whilst also taking up interesting offers such as singing at the premiere of a horror film dressed as monks and entertaining visitors to National Trust Properties.

Gloriana was formed in 2016. The members of the choir were handpicked from top choruses and chamber choirs across London and the South East and since then they have given several highly successful and well received concerts. Their programmes are wide and diverse and always have a high proportion of new music and compositions by female composers. Their first CD was released in October 2020. 

Classic FM recorded and filmed two pieces to go on their website the Mayor of London invited them to sing at his Christmas carol concert in Southwark Cathedral.
