Castro Rego began her career as an art director before moving to account direction. She was most recently at 9 Communications where she was the director of planning and strategy.
Castro Rego has worked across health, banking, consumer and entertainment clients.
Her team will be part of H+K’s global content studios network of more than 100 consultants with a 24/7 response.
She said: "I believe that the power of strategy, deep knowledge of the markets, anticipation of trends and the consistent use of the date, aligned with the power of creativity and innovation are the right recipe for consistent and winning work."
The Global Studio network includes content and publishing strategists working alongside film directors, and data analysts working with designers – all focused on the same client-centric goals whether it’s creating a new identity or a full-length documentary, an exhibition stand or the interactive experience.
Piedade Guimarães, H+K Portugal’s director-general of operations, added: "The hiring of Ana responds to our agency's ever-growing client base and the increasing need to implement global communications strategies."
