WSM is honored to donate our efforts to Boysville’s noble cause of helping children in need. 

“Boysville Children’s Home and Shelter, the Home with a Heart, was founded in 1943 as a result of Rev. Don Holiman’s observation of orphaned, homeless and abandoned boys sleeping in San Antonio’s Travis Park. Today, we provide a continuum of trauma-informed services and care for children and caregivers affected by abuse, neglect, and family crisis. Through holistic wrap-around services, we provide each child the opportunity to heal from past trauma while focusing on their future.”
