At the forefront of championing health and well-being for vulnerable populations, the Mobile Foundation for Health, Security, and Rehabilitation (MHSR) is a youth-led non-profit organization founded in 2014. MHSR is dedicated to improving the lives of marginalized communities, particularly those most at risk of infections, diseases, and social injustices, including stigma, discrimination, marginalization, and violence. MHSR specializes in innovative healthcare delivery, capacity building, advocacy, research, and partnerships. We focus on children, young men and women in all their diversity, prioritizing adolescent girls living in slums parts or rural or semi urban areas with low economic standard of living without basic amenities, the Sexual Minority Community, and other Most-at-Risk Populations (MARPs).
