MariaTeresa Chavez


MariaTeresa has worked across several industries in multinational corporations. She has worked in the design, development and implementation of engineering, capital and continuous improvement projects as well as operational risk, long term strategy and sourcing, in Argentina, Brazil, Colombia, Chile, Ecuador, Perú and the United States.

The opportunity to work around the world is something that appeals to MariaTeresa’s love of traveling. It’s this sense of adventure that also inspires her weekends closer to home too, where you’ll find her hiking, parasailing or climbing. Now that she has ticked snowboarding in the alps and skydiving off her bucket list, she has her sights set on a bungee jumping. For someone who says that she’s ‘in love with places I’ve never been to’, a role at Partners in Performance is the perfect way to travel and ‘collect memories’ while contributing meaningfully to organisations around the globe.
