Mother Mary Primary School

Mother Mary Primary School provides holistic training based on ethical Christian principles, preparing children for a dynamic society and a better future. In 2020 the school opened its doors to 208 boarding and day scholars, and today it serves 307 students, employing 34 staff and faculty members who are committed to serve the educational needs of their students.  Principal Asiimwe Collins has designed a rigorous program for this age group with a system of tests, exams, progress evaluations, and regional academic competitions. The school’s first candidates will sit for national exams in October of 2023.

St. Thomas Aquinas High School

In 2002, DCS helped fund STAHS, an esteemed institution in Western Uganda and the local high school which receives students from MMPS. Graduates of STAHS have advanced to become doctors and nurses, engineers, architects, librarians and teachers, with some returning after graduation to teach at their alma mater. Together, these schools set the stage to improve livelihoods and promote a culture of prosperity and hope within their community. DCS is committed to continued support, helping these schools reach their educational goals.
