The Institute of the Daughters of Mary Help of Christians (Salesian Sisters of St. John Bosco) was founded by St. John Bosco and St. Maria Domenica Mazzarello in 1872 in Mornese, Italy. The small seed blossomed into a fruitful tree that has spread its missionary presence in more than 70 countries all over the world with more than 15,000 Sisters living and working with the young in an educative presence characterized by the Salesian Preventive System. They are officially called the FMAs or the Figlie di Maria Ausiliatrice which is the Italian translation of the Daughters of Mary Help of Christians.

In 1955, when China closed its doors to the presence of Catholic missionaries due to the Communist takeover, the Salesian Sisters went to Hongkong and then to the Philippines. After 50 years of its educative presence, the Salesian Sisters of St. John Bosco of the Philippine province can now be found in 17 communities in Luzon and the Visayas. Here, they involve themselves in various forms of apostolic acts such as the oratory youth centers, catechetical apostolate, schools, street children, boarding houses, training centers, technical vocational schools and in many other various forms of human-social promotion such as medical-dental care and livelihood programs.

In Mabalacat, Pampanga, the Mary Help of Christians School was established in 1995 through the generous donation of Ms. Luz Morales. The aim was to educate the young in the spirit and style of Don Bosco and Mother Mazzarello and to accompany them in their journey of becoming mature apostles among their peers, builders of Christian community as children with Christian conscience, commitment and competency. They started with pre-school, elementary and high school education.

Moreover, realizing the need to help uplift the lives of the disadvantaged families particularly the young women in nearby localities further displaced by the eruption of Mt. Pinatubo in Pampanga, the Salesian Sisters saw that development through the provision of technical education was imperative. Thus, the Mary Help of Christians Technology Center for Women was established on August 15, 1995 to provide skills training to poor young women both graduates and non-graduates of secondary education (high school) who dream of having a brighter future through acquisition of technical-vocational education. The Center also serves as the pilot training Institution for the implementation of “technologies for women in non-traditional occupation” by training them to be highly skilled workers simultaneously instilling proper work attitudes so that they could have greater opportunities of having decent lives as members of the productive workforce of society. This was made even timely with the industrialization boom of the Clark Special Economic Zone. They opened the Computer Secretarial, Garments and Food Technology Courses and the trainees studied with the Study Now Pay Later (SNPL) scheme.

The work has flourished by the increase in number of enrollees and by the introduction of the Dual Training System (DTS). In this system, the company accepts the trainees for training, gives them hands-on experience and pays them 75% of the minimum wage with an opportunity for immediate absorption. By the end of the course, the trainee is able to receive education and employment at the same time uplift the lives of their families. The DTS Approach started in 1997 with the introduction of the Electronics and Computer Technology Courses. Then in 1999, Hotel and Tourism Technology course was offered. In the year 2000, the Business & Office Technology was initiated and in 2004, Sales Technology course was opened wherein for the first time boys were accepted.

Due to the growing number of population and the needs arising from the vast work, the Center became a separate entity from its mother school, the Mary Help of Christians School. Thus, on 2004, it became the Mary Our Help – Technical Institute for Women. The new name brought new zeal and enthusiasm to strengthen vocational training as a response to the needs of the poor young of today. After some years, in year 2008, Technical Education and Skills Development Authority (TESDA) had implemented the re-registration of all courses which led to the evaluation and modification of the curriculum and the retention of Electronics Technology, Industrial Electronics, Business and Office Technology and Travel Technology courses. In this year also the new St. Joseph Community was erected to manage the Technology Center which gave more focus and direction to the educative mission.

In 2015, again through the recommendation of TESDA, the courses had been modified in order to be aligned with the new training regulations this Institution has set. The following became the new group of courses: With Training Regulations (WTR), Electronic Products and Assembly Servicing NC II, Travel Services NC II, Bookkeeping NC III and With No Training Regulations (NTR), Industrial Electronics and Business and Office Technology.
