Every great school has a story, and at Mitua Girls Senior School, that story is increasingly being associated with one name—Chief Principal Angelina Kosgei.
At a time when many schools are searching for the formula for academic excellence, Mitua Girls appears to have found its answer in purposeful leadership, teamwork, and an unwavering belief in the potential of every learner. Under Kosgei’s stewardship, the school has quietly but steadily transformed into one of the most admired girls’ institutions in Western Kenya.

The numbers speak for themselves. From a mean grade of C- in 2020 to a consistent C+ performance today, Mitua Girls has demonstrated that progress is not always about giant leaps, but about consistent improvement year after year. The 2025 KCSE results, where 299 students attained university entry grades, are a reflection of a school that has embraced a culture of excellence.
Yet beyond the impressive statistics lies something even more inspiring—a leader who believes that every girl who walks through the gates of Mitua Girls deserves an opportunity to dream, grow, and succeed.
Those who know Angelina Kosgei describe her as a principal who combines firmness with compassion, discipline with encouragement, and high expectations with genuine care for her students. She has cultivated a school culture where hard work is celebrated, talent is nurtured, and no learner is left behind.
Her influence is visible not only in academics but also in the vibrant co-curricular achievements that have placed Mitua Girls on the national map. Whether in science and innovation, athletics, drama, or environmental conservation, the school continues to produce young women who are confident, creative, and ready to make a difference in society.
What makes the Mitua Girls story particularly special is that it is not merely about grades or trophies. It is about building futures. It is about creating an environment where young girls discover their abilities and are empowered to pursue their ambitions without fear.
Today, Mitua Girls is increasingly earning recognition as a school of choice in Bungoma County and beyond. Parents see a school where their daughters can thrive academically and personally. Students see a place where their dreams are taken seriously. Teachers see a supportive environment that values professionalism and teamwork.
As the school continues to scale new heights, Chief Principal Angelina Kosgei remains a shining example of how visionary leadership can transform an institution and inspire an entire generation.
Indeed, the rise of Mitua Girls is more than a success story—it is a testament to what is possible when dedication, passion, and a belief in every child’s potential come together under exceptional leadership.
