He has lectured for the Institute of Bankers and Chartered Accountants Ireland and has contributed to multiple media outlets on issues relating to risk, control and sustainability.

We are excited to welcome Marc as a Partner in our Sustainability practice. His depth of experience across risk, assurance and ESG reporting will significantly enhance our ability to support clients as sustainability regulation, reporting standards and assurance expectations continue to evolve. Marc’s appointment reflects BDO’s commitment to providing commercially focused, technically robust advice that helps businesses navigate complexity with confidence.
I’m very pleased to be joining BDO as Sustainability Reporting and Assurance Partner.

Businesses need clear, credible and practical support to respond to these demands. By combining BDO’s strong sustainability and advisory platform with deep reporting, risk and assurance assurance and risk expertise, we can help clients strengthen governance, build trust with stakeholders and turn sustainability obligations into a source of long-term value.
