The firm says it recognises continuing development and growth following four director promotions earlier this year.
Ms Byrne joined KPMG in 2014 and specialises in the audit of asset management structures including a focus on real estate.
Dermot Dempsey, Head of Audit at KPMG in the Crown Dependencies, said: “Theola’s promotion reflects continued strong growth in our audit services across all financial services sectors. I am delighted to see Theola come through as an Audit Director, having played a key role in that growth.
“Our continued drive to deliver the best client service experience, audit quality at the core of everything we do and innovation in how we do it gives us confidence of further success for the future.”
Brian Bethell, Deputy Head of Audit, added: “Having worked with Theola on a number of clients and with wider department matters, this promotion recognises her contribution to the firm’s growth and people initiatives. As part of our leadership team Theola will be a great example to future leaders.”
