Having their head office in India, the group had spread into many countries in Africa and Latin America. The group is well-known for their contribution to Capacity Building of Women and Children and Minority and Marginalized. As a natural growth the work of the sisters had grown and seen the developments like Schools, Colleges and Universities. Today DMI-ST. Joseph Group owns and run Universities in various African countries and in India.
The history of the St. Joseph University In Tanzania dates back to the launch of the St. Joseph College of Engineering and Technology in Dar-es-Salaam in 2004 and St. Joseph Institute of Information Technology in 2005 at Songea. Both the colleges were accredited with National Council for Technical Education (NACTE) and in the year 2011, they were elevated to the status of the University under Tanzania Commission of Universities (TCU). What was a group of Colleges in the yester years had matured and grown to be a University and is proud to remain here to serve the people. While others were starting Colleges and Universities in simple Arts and humanities, DMI decided to contribute their mite in Science, engineering and ICT. DMI did this answering the call of the Catholic Church in capacity building and the Tanzanians.
St. Joseph University owes its origin and existence to the patronage and support of His Eminence Polycarp Cardinal Pengo, Archbishop of Dar-es-Salaam and His Grace Norbert Wendalin Mtega, Archbishop of Songea. They found the need in the higher education scenario in the country and invited DMI to fill the gap with the expertise in the education field. DMi embarked on its mission with a clear mission and vision which detailed and spelt out its very purpose of existence.
