We provide support for victims of sexual assault and their families, but we also work to end it. For good. Forever. We're not messing around. Day One provides support for victims of sexual assault and their families, and serves as a resource for the larger community on issues relating to sexual assault, child sexual abuse, domestic The 24-hour Victims of Crime Helpline (1-800-494-8100). Day One's mission is to reduce the prevalence of sexual abuse and violence, and to support and advocate for those affected by it. Day One's vision is to create a community that is free of sexual abuse and violence through leadership and action that is responsive to the needs of the community. Day One was established in 1973 by a group of women concerned about the increasing problem of sexual assault and the lack of services and information available to victims and the public.
