Marklund was founded in 1954 when a nurse by the name of Claire Haverkampf agreed to provide foster care for an infant named Mark William Lund who was born with Down Syndrome and severe cardiac issues. She and her family then took in more developmentally disabled and medically fragile children, establishing the Marklund organization. Today, Marklund consists of three campuses--Marklund at Mill Creek, an adult residential and therapeutic facility in Geneva, Marklund Wasmond Center at Little Angles in Elgin, and Marklund Philip Center, both residentiaal and therapeutic services for children and adults, and the Marklund Day School in Bloomingdale. Ninety-six clients reside in six homes on the Geneva campus, while 57 resident in the Wasmond Center and 21 clients currently reside in the Philip Center. The Philip Center features a 24/7 skilled nursing unit. The Day School provides special education for children ages 3-21 who have multip medical needs and those who are on the autism spectrum.
