We remember

Mr. Manasse Mbiti Mbui

1959 – 2021

Loving husband, father, great leader, a good friend and great colleague

The Late Mr Mbui joined St Mary’s Mwea Girls’ High School on 28th April, 2010. He taught CRE and Geography. He was exceedingly knowledgeable in his area of specialization and that, coupled with his many years of experience enabled his students to continually post impressive results in National Examinations

Professionally, he was a strategic thinker, a visionary who was brilliant, innovative and creative. As such, he contributed much to the development of the school and was a member of the Senior Management Team. He not only generously gave us his knowledge, his expertise, his skills but was also a role model to the young people.
