“Over the coming weeks and months, I look forward to getting out and about and meeting as many of our key stakeholders as possible.”

“It turns out the gem we were looking for was under our nose all along. For against all the candidates that emerged through the process, Ann-Marie stood out in terms of her energy and passion for Audit Wales, the clarity of her vision for the role, her blend of relevant experience and expertise and her fit with the rest of the new senior team.”
