Founder portrait

“I am committed to expanding OVAH’s integrated approach—combining prevention, empowerment, survivor support, and advocacy—to reach more communities and strengthen systems that protect and empower women and girls. My vision is a Tanzania where every woman and girl can live free from violence, with full agency, dignity, and opportunity. ”

— Modesta Joseph, Founder & Executive Director

Our Founder’s Vision

Over the past five years, I have witnessed OVAH Tanzania grow from a small, youth-led initiative into a nationally recognized, evidence-driven organization working at the forefront of sexual and gender-based violence (SGBV) prevention and response. This journey has been guided by a clear intention: to build solutions that are not only responsive, but transformative in addressing the root causes of violence and inequality.

From the beginning, my vision has been to design programmes that are practical, innovative, and grounded in the lived realities of women, girls, and young people. Through initiatives such as Elimika na Mwajuma, we have used digital storytelling and animation to challenge harmful norms and expand access to knowledge on SGBV and sexual and reproductive health and rights (SRHR). Through Move with Pink (Pink Bajaji Initiative), we have created pathways for women, including survivors of violence, to access dignified livelihoods while contributing to safer public transport systems for women and girls.

I have also prioritized working beyond individual-level interventions to influence systems and institutions. OVAH engages schools, transport workers, employers, and community leaders to strengthen safeguarding mechanisms, shift behaviors, and promote accountability. These efforts are supported through capacity building, advocacy, and strategic partnerships that aim to create environments where safety and gender equality are actively upheld.

What continues to drive this vision is the belief that young people, especially young women, are powerful agents of change. Through our work, we have not only reached communities with critical information and services, but also supported young people to take on leadership roles and drive change within their own spaces.

Our Values

These core values guide everything we do and shape our approach to creating lasting change in communities across Tanzania.

Social Justice

Social justice lies at the heart of our mission. We strive for a Tanzania where every individual is treated with dignity, respect, and fairness. We work to eliminate systemic barriers and ensure equitable access to opportunities, resources, and basic human rights for all, especially women and children.

Co-creation and Leadership

At OVAH, we believe that those who are targeted by our programs should also be the key drivers of what we do. We prioritize the active participation of our beneficiaries in the design, implementation, and evaluation of our initiatives.

Learning and Collaboration

Our work is rooted in continuous learning and growth. We embrace the opportunity to learn not only about the complex issues we tackle but also about the communities we serve, the intersectionalities of those issues, and how to evolve our approaches.

Impact and Innovation

We are committed to addressing sexual and gender-based violence in Tanzania through innovative solutions that create tangible, lasting change. Our projects are designed to be both impactful and measurable, ensuring they lead to meaningful progress.

Collective Care

We understand that a thriving community is built on the well-being of its members. This extends to our team—board members, staff, ambassadors, and volunteers—as well as the communities we serve. We prioritize empathy, compassion, and mutual respect.

Our Focus Areas

We concentrate our efforts on four key thematic areas that are essential for creating lasting change in gender equality and violence prevention.

Combating Sexual and Gender-based Violence

Our primary focus is preventing and responding to SGBV through comprehensive programs that address root causes and support survivors.

Gender Equality and Women's Empowerment

We work to advance gender equality by empowering women and girls with skills, knowledge, and opportunities for leadership.

Adolescents, Youth, and Women's Engagement and Leadership

We prioritize youth and women's participation in decision-making processes and leadership development at all levels.

Sexual and Reproductive Health and Rights

We advocate for and educate about sexual and reproductive health and rights, ensuring access to information and services.

Sustainable Development Goals

Our work directly contributes to achieving the United Nations Sustainable Development Goals, creating measurable impact for communities across Tanzania.
