About 23 years ago, Jim Henry and four other Kalamazoo-area professionals launched the Southwest Michigan Child Trauma Assessment Center at Western Michigan University. At the time, few people knew how traumatic experiences can negatively affect the developing brain of a child. But the founders of CTAC did. And the center they created to assess traumatized children has not only become the model for similar centers across Michigan and in Colorado, but also has effected change in the state’s child-welfare system and beyond.
