MAMTA was established in New Delhi in 1990. It works in 14 states of India and also in Nepal and Bangladesh. It has built the capacity of over 150 CBOs on issues related to sexual and reproductive health, HIV and care & support interventions, with a special focus on young people, children and women. It has also contributed significantly to policy and programme formulations at state and national levels especially on the issue of HIV.

MAMTA’s mission is to empower underserved and marginalised individuals and communities through gender-sensitive participatory processes to achieve optimal and sustainable health and development.

MAMTA’s strategic areas of work with the Alliance are:

MAMTA provides quality and cost-effective primary health care services to the urban poor focussing on women and children. While improving the health of women and children, the organisation has adopted a lifecycle approach, which includes working with adolescent boys and girls to achieve better health outcomes. The organisation is working towards creating awareness on the issue of gender equity through programmes and activities that encourage women’s empowerment and participation.

MAMTA initially focused on the health of women and children as its main target groups, but soon it realised that, in order to bring about a significant change in women's health status, their behaviours and attitudes required intervention at an earlier stage in their lives. This led to the development of programmes for adolescents and young people on education, health and entrepreneurship development. Today, MAMTA has a nationwide network involving 150 partners in various states that influence policy environment on adolescent/young people’s reproductive and sexual health and rights.
