It is with great pleasure that I invite you to familiarize yourselves with our projects and activities. Since more than 57 years, the Archdiocese of Arusha plays an active part in the people’s lives in Tanzania, and we are happy to inform you that contrary to the worldwide decline of disciples of the two major Christian Churches we enjoy constant growth with now close to 538.000 members within an area of 67.340 sq km.

With our associates in the various projects we already work closely with the communities in the seven districts – Arusha District, Arumeru, Monduli, Longido, Ngorongoro, Karatu and Arusha rural – of the Archdiocese in order to help create a sustainable living for all.

With best wishes and blessings,
AAIDRO Executive Director

Education Department

“Education” is supposed to be: Lots of smiles, friendly determination, energetic approach to things – and of course never stop to have an open, inquisitive mind. All the right prerequisites for the task, the overall coordination of all the educational activities of the Catholic Archdiocese of Arusha. As well, to ensure that the respective curricula are implemented according to the Tanzania Episcopla Conference (TEC) Ministry of Education and Culture (MOEC) Christian Social Services Commission (CSSC) Vocational Education and Training Authority (VETA) and Education and Training Institutions in the Archdiocese.

Health Department

Providing medical care – be it in setting up a doctor’s office or pharmacy – is already an undertaking by itself that requires not only the expertise of course, but also lots of stamina, and sufficient funding. Looking back at the history of the Archdioceses Health Department, and its vision to serve people in its vast area of 67,340 sqkm, still sounds adventurous nowadays. And yet, the vision of the 1980s came true.

Preschool Department​

A total number of 27 preschool buildings were constructed and well furnished. Starting as an Assistant Coordinator in 2005 and being a Coordinator and in charge of the programme since 2013, Stella Aloyce Mollel witnessed the program to grow, prosper and become a success story. ​
