Ar ol dilyn gradd BA anrhydedd mewn Hanes ym Mhrifysgol Cymru Aberystwyth, aeth ymlaen i astudio y llais yn ol radd yng Ngoleg Cerdd y Guildhall yn Llundain ac yna dilynodd Gwrs Opera yn y Coleg Cerdd Brenhinol yn Llundain. Bellach y mae wedi cael y cyfle i drafeilio i wahanol wledydd i ganu gan gynnwys Cwmni Opera Brenhinol Norwy, Gwyl Aix en Provence a Thy Opera Lyon yn Ffrainc, ynghyd a gweithio i gwmniau Opera North, Glyndebourne, Cwmni Opera Cymru ar Cwmni Opera Brenhinol, Covent Garden yn Llundain. Ym mis medi eleni fe fydd yn ymuno a chwmni Opera Glyndebourne ar daith i gymeryd rhan yn opera Mozart, Priodas Figaro. Mae Sion hefyd yn aelod o Gor Godre'r Aran ac yn perfformio gyda'r cor pan fydd gartre.

Yn ystod y flwyddyn diwethaf daeth llawer o newid i Sion gan iddo golli 11 stone o bwysau yn ystod y flwyddyn ac felly edrycha ymlaen yn fawr at ymuno ac un cymal o daith Cerddwn Ymlaen gan na fyddai wedi gallu meddwl ymuno ar daith hon lai na blwyddyn yn ol.

After Gaining his BA hons degree in History at the University of Wales Aberystwyth, Sion went on to study voice at postgraduate level at The Guildhall School of Music and Drama before completeing The Opera Course at The Royal College of Music in London. He has traveled extensively and performed with The Norwegian Royal Opera in Oslo, appeared at the Music Festival of Aix en Provence and Lyon Opera, as well as performing closer to home with Opera North, Glyndebourne Opera, WNO and Royal Opera House Covent Garden in London. In September he will return to Glyndebourne to perform in their touring production of Mozarts Marriage of Figaro. Sion is also a member of The Godre'r Aran Male Voice Choir and joins them whenever he is at home in Bala.

During the past year a huge change has happened in Sion's life as he has shed 11 stones of weight through dieting and walking and joining one leg of Cerddwn Ymlaen would have been out of the question. Sion is glad of the opportunity of joining this walk as supporting the work of the Air Ambulance is vital living in such a rural community!
