Child Advocacy Center Services

Child Forensic Interviews

A child forensic interview is a developmentally sensitive and legally sound method of gathering information from a child about allegations of abuse, neglect, or exposure to drugs or violence. At Willow Tree Cornerstone Child Advocacy Center, our child forensic interviewers are specially trained to ask children non-leading, non-suggestive questions that are appropriate for the child’s age and development. This helps to minimize trauma by ensuring that the child is able to tell someone what happened in their own words, to one adult. Each child forensic interview is recorded and all agencies involved in the child’s case observe the interview from another room at Willow Tree. When the interview is finished, the recording will be used by law enforcement and the district attorney’s office as a part of the child abuse investigation.

Medical Evaluations

Children's Wisconsin logoWillow Tree is proud to partner with Children’s Wisconsin to provide on-site medical evaluations for children who have been abused or neglected. Our nurse practitioners from Children’s Wisconsin specialize in the medical evaluation of child maltreatment. They look for signs indicating sexual or physical abuse, neglect, or drug endangerment. These findings can later be used as evidence if the case is referred for charges or goes to court. A medical evaluation includes medical history, physical exam, and, when appropriate, documentation of any signs of abuse, collection of physical evidence, diagnostic testing, testing for other medical conditions that could be mistaken for maltreatment, treatment and referrals.


During each appointment at Willow Tree, children and their caregivers are able to meet with an advocate and members of the investigating team. Advocates help the child and family understand what is happening, while ensuring the child and family receive the resources and referrals they need to begin to heal. In addition to providing immediate support, advocates also maintain contact with families throughout an investigation. This may include providing updates on the status of the child’s case and accompanying the family to court.
