She is Organist and Director of Music at the church of St. Lawrence Jewry, the church of the Corporation of London, where her series of Tuesday lunchtime recitals continue a century-long tradition of organ music as midday respite for all, whether City workers, tourists, or afficionados. The series has been enhanced by a fine new Klais organ, installed in 2001.

Recordings have included a Guilmant disc for EMI at St. Marylebone Parish Church, London, a disc of English Romantic organ music for IFO, from Muenster Cathedral in Germany, and Bach's Goldberg Variations for Mollterz at St. Lawrence Jewry (on the 5- stop Chapel organ) . Future releases include "Homage to Schweitzer" from St. Lawrence, and the Reubke Sonata from St. Giles Cathedral, Edinburgh. She has broadcast frequently for the BBC and RTE radio.

She teaches at Trinity College of Music, London, at St. Giles International Organ School, London, and Shrewsbury School. Oundle International Festival, Edinburgh Organ Academy and Eton Summer School have been among recent teaching and performing engagements. Her diary in the next year includes appearances in London, Dublin, Luxembourg, Germany, inter alia.

Uniquely, she has been has been the catalyst behind three major instruments in London, those at St. Marylebone (Rieger) in 1987 and at St. Lawrence in 2001, and the William Drake organ for Trinity College of Music, Greenwich, installed in 2003. She is currently involved in other organ advisory projects.

Twelve years ago, Catherine Ennis founded the London Organ Concerts Guide, which seeks to persuade a wider audience that the organ can be of more than minority interest. She is President of the Incorporated Association of Organists (term 2005-2007), a Trustee of the Nicholas Danby Trust for student organists, council member of the Royal College of Organists, and writes for various musical journals.
