Terror and violence in Perú (Sendero Luminoso) made it necessary to look for new fields of application for the missionaries in Peru. The neighboring country of Bolivia offered itself as such. The first team – 1 SMB priest and two laypersons – started their mission in 1992. In 1993, a new team of two was added.

The two main areas of missionary activity were the poor areas of the lowland Santa Cruz and the capital of La Paz in the highlands.

The last SMB member returned in 2012 after 17 years – building two parishes and two health centers based on natural medicine.

All four parishes, established by SMB members and their laity-team, were handed over to the local church.
