The group has the archbishop of the Roman Catholic Archdiocese of Davao as their bishop-protector to continue their existence and ministering to various convents spread all over the country.Its foundation was for the purpose of responding to the needs of spiritual growth among the peoples of the vast territory of the newly created diocese covering the whole Davao provinces.

Presently, TDM sisters are working in different diocese all over the Philippines.Number of pertually professed sisters reached more than 50 and maybe considered sooner to become a religious institute of pontifical rights which means they could have their own constitution and chapter as a regular congregation of the Catholic Church. They are maintaining communities in the dioceses of Digos, Mati, San Fernando in La Union, Jaro, and of course in Davao. They are in charge of schools, retreat houses, community development programs and other ministries as requested by the local bishop.
