Our People

The women who make up Atira’s staff and Board are diverse, engaged, and committed to the work of ending violence against women. They are wildly talented and it shows.

The Board of Directors develops goals and plans for the Society and is accountable for all legal and financial activities.

While the Board makes policy decisions and guides management activities, the day-to-day operations are left to the Chief Executive Officer (CEO) and a team of inspiring women.
