I worked as Vice-President and later Managing Director of Teletec International, a distributor of text telephones, from 1991 to 2007. In 2000 a captioned telephone relay service was started and operated until 2007, when it closed due to lack of government funding for alternative relay services.

From 2007 onwards, I was Director of AccEquE Ltd, a consulting company on enhanced accessibility and equality in electronic communications for deaf, deafened, deafblind and hard of hearing people. In 2010, I was appointed as one of the three Vice-chairs of the Joint Coordinating Action on Accessibility and Human Factors (JCA-AHF) at the International Telecommunications Union (ITU), a UN agency based in Geneva, Switzerland.

I am the editor of the ITU-T F.703 document relating to Total Conversation, and co-editor of the ITU-T F.Relay document at Study Group 16/Question 26. In 2013 I was appointed Chair of Deaf Access to Communications (DAC), a special interest group (SIG) under the United Kingdom Council on Deafness (UKCoD). In 2021, I resigned as Chair of DAC to become Chair of Deaf Access to Alternative Relay Technologies (DAART), focusing on the introduction of a captioned telephone relay service in the UK.
