About Mairead Virtual Assistant LLC

I’m Marjorie O’Rourke, founder of Mairead.

I launched Mairead Virtual Assistant LLC after 15+ years supporting C-suite executives, directors, and large teams as an executive assistant. I’ve worked in fast-paced corporate environments, managed multiple calendars and inboxes, led board-level communication, and kept leadership aligned through systems and strategy.

Now, I bring that experience to small business owners, entrepreneurs, and Chambers of Commerce—offering both high-level virtual executive assistant support and strategic online business management (OBM) services.

My mission is to give busy professionals the gift of time, structure, and momentum. As a full-service administrative support agency, we help growing businesses streamline operations, manage their teams and projects, and scale with confidence.

Whether you need a trusted virtual executive assistant to manage the day-to-day or an OBM to oversee systems and strategy, I’m here to support your next level of growth.
