Our Team

"The truth is that teamwork is at the heart
of great achievement"


With DURA|NATURA, Engracia created the agency she would want to have access to herself as an owner of a great new organic or sustainable product, needing help to place it in the market. Her passion for Sales, New Business, languages, sustainable products and the desire to help others brought our agency to life. She is here to help you with all things Sales, to make sure your brand will be able to enter two of the most attractive markets in Europe and beyond successfully. She is looking forward to hearing from you, and to craft the right strategy for your products together.
