The foundation's primary objective is to provide aid to underprivileged communities locally and globally, a role she has undertaken since 2018.

Mariela is not only an advocate for professional development and expansion but also a proactive contributor to the field. Her authorship of articles on Human Resources Management and her recent certification as a Certified Life Coach in 2022 reflect her zeal for personal growth and enhancement.
