      <PrimaryExemptPurposeTxt>Our Sisters Keeper (OSK) fosters social connection for women through support groups, individual life coaching, and access to healing spaces that address intergenerational trauma, social isolation, depression, the challenges of parenting, abuse, and discrimination. We work under a framework of healing centered engagement. OSK helps women to realize they are not alone and begin on the path to healing. We provide women with actionable goals, accountability for meeting those goals, encouragement along the way, and celebration upon achievement. We deliver customized life skills and professional support that would otherwise be inaccessible.</PrimaryExemptPurposeTxt>
