Keeping Families Together Act of 2007

Keeping Families Together Act of 2007 - Amends the Public Health Service Act to allow the Secretary of Health and Human Services, acting through the Administrator of the Substance Abuse and Mental Health Services Administration, to award competitive matching grants to states to establish systems of care to provide mental health treatment and services to all children who are in the custody of the state or at-risk of entering into the custody of the state for the purpose of receiving mental health services.

Requires states to use grant funds for certain activities, including to: (1) expand public health insurance programs to cover community-based mental health and family support services for such children and their families that will be sustainable after the grant has expired; (2) provide outreach and public education concerning available programs and activities; and (3) provide training and professional development for personnel who work with such children.

Requires the Administrator to establish a task force to examine: (1) problems of mental health in the child welfare and juvenile justice systems; (2) issues with respect to access by children and youth to mental health services; and (3) the role of federal agencies in promoting access by children and youth to mental health services.
