[14] Parsitau is involved in promoting equitable development for girls, women, and other vulnerable communities in Kenya.
High illiteracy levels propelled her to ensure Maasai boys and especially girls obtained education, as they were affected by sexual harassment, physical and gender-based violence and child neglect.
Her efforts have had a positive impact on the community, enabling young Maasai females to follow their academic aspirations.
Parsitau advocates for the development of a just society that ensures women and girls have equal opportunities and has focused on inspiring social and gendered change in her Maasai community and beyond.
