The Short Story of PLU

Christine Walker | Founder

Christine Walker is now an entrepreneur, board member, author, speaker, and business coach.

In 2004, she started as one of the first "mobile assistants" (yes, indeed, "New Work" was already possible in 2004!) as a PMO assistant on an international major project at a leading management consulting firm. That was the beginning of her successful career. Today, her company is the market leader in top assistant services.

The company operates globally and is an expert and pioneer in #new_work.
