Profile and expertise

Why I love what I do

My job is one of my passions. I love communications—the kind that are built on listening, adapting, and persuading. I love communications that have an impact and make it possible for our clients and their organizations to reach their business objectives. I like making a difference in the lives of our clients and our colleagues. That’s why CASACOM exists. I’ve always felt the need to make an impact. During my years in politics, in diplomacy, and as the head of communications for major organizations, I’ve always believed that communication can change almost anything.


CASACOM is a lot more than a communication agency. It’s a place for discovering, exchanging views, and going the distance, where I have the privilege to live with people who share my values—especially my belief in striving, always, to be the best you can be. We pour our energy into working at the crossroads between business and communications, solving problems for executives so that their organizations can achieve even more. We have the good fortune of working with exceptional clients who trust us with their most valuable asset: their reputation. It’s a privilege for which we are truly thankful.

What else…

Even though I love my job, there’s a lot more to my life than work. I love being active (especially running, Pilates, horseback riding, and skiing), reading, meditating, travelling, gardening, cooking, and more than anything else, seeing others succeed. That’s why I launched Brave, an interview series with women who are making their mark in the world. Most importantly, I’m married to Louis‑Martin O’Neill, a lawyer who specializes in corporate litigation, and I’m the mother of two boys: Philippe and Henri.
