Cyber risk and GRC leader at Cardinal Health who led $1.2B in M&A and divestiture security due diligence.
What I'm looking for
At Cardinal Health, I lead the enterprise Cyber Risk Management Strategy and Framework, turning technical risk into decisions leadership can act on. I chaired the IT Risk Advisory Board and led cybersecurity due diligence for M&A and divestiture deals totaling $1.2B.
I built Cardinal Health's Third-Party Risk Management strategy and led a 17-person team across the US and India. I established vendor Minimum Security Standards and implemented ServiceNow VRM, while developing risk metrics for executive leadership.
Earlier, at Endsleigh Insurance Services Ltd., I supported infrastructure and system changes for PCI compliance. I'm now focused on AI governance, applying NIST AI RMF and ISO/IEC 42001 to help organizations use powerful systems with trust.
