Pastor Gareth Leyshon
I love Jesus, Jaffa Cakes and science – in that order. I fell in love with science when I discovered an astronomy book, aged 7. But I discovered Jesus was real when I said the first serious prayer of my life, when I was 11. Since the universe had a head start, I got as far as completing a PhD in Astrophysics at Cardiff University before entering seminary. I was ordained priest in St Dyfrig’s on 5 May 2007 and served there until 2012. I was then parish priest in two Cardiff city parishes, St John Lloyd and St Philip Evans, until I left parish ministry to become a full-time missionary with the Sion Catholic Community for Evangelism in 2018. Archbishop Mark called me back to become Parish Priest over our four pastorate parishes in January 2023. At seminary I discovered I was mildly on the autistic spectrum – my key weaknesses is in reading body language. I do care about how all my parishioners are feeling, but you may need to use words to tell me. Thank you for your understanding and prayers.

Alan de Ste Croix (in formation for the Permanent Diaconate)
Áine-Zélie Popplestone (Mrs) – Pastorate Engagement Officer
I am passionate about God, the Bible, history, hair, singing and extreme sports! I have been married to the wonderful Tim for nearly 10 years, who I met at a Bible study and bonded over our shared passion for rock climbing and hiking. I am an experienced Bible teacher and catechist and love building people up in the faith. I have over 8 years church youth work experience and previously co-ran a student chaplaincy. I have served in many capacities in churches over the years, including running visual and sound systems aged 12, children’s liturgy, youth and activities coordinator at a previous church, reading, cantoring, welcoming, filling whatever gaps that has needed filling.
My career background is broad and diverse having worked in business, academic research, teaching/lecturing and working with adults and teenagers with SEN and ALN. I love my history and Biblical trivia, which often come out at the most random of times and due to my obsession with historical anthropology people often joke that I am a few hundred yeas old.
As the engagement officer I love connecting with people, identifying needs and supporting people to grow in faith. I do a broad array of things from setting up new ministries and new opportunities. I support people to engage in church that helps them use their gifts and talents. I mentor catechists and support them to grow in sharing faith with others. I also do a lot of other things, but its hard to keep track!

Pastorate Leadership Team
The Pastorate Leadership team is a small group of key volunteers drawn from across the parishes who meet every fortnight to reflect on the pastoral and spiritual needs of our communities. Here we plan events open to all members of the Pastorate, and work out how to share resources and timing of more local events without clashing. We also reflect on the Scriptures for the coming Sunday Masses and this often informs Pastor Gareth’s homilies. Membership is by invitation of Pastor Gareth and is currently:
Joe Biddulph (St Dyfrig’s)
Teresa Bressington (All Hallows)
Christina Canale (the Rhondda Parish and All Hallows)
Alan de Ste Croix (St Dyfrig’s – member by e-correspondence)
