Demonstrated capability to support accountability and follow-through, including proactive engagement with senior leaders and cross-functional teams to monitor progress and surface risks or delays.
High level of proficiency with Microsoft Office and collaboration tools, including Outlook, Word, Excel, PowerPoint, Teams, and SharePoint, with the ability to independently produce executive-ready materials.
Experience using modern productivity, automation, and digital tools, including AI-enabled solutions where appropriate, to streamline administrative workflows and improve efficiency.
