Mercy Intensive Early Intervention Program

The Mercy Kids Intensive Early Intervention Program assists toddlers and preschoolers through kindergarten age who’ve been diagnosed with an autism spectrum disorder (ASD) or pervasive developmental disorder.

This innovative program is based on the principles of the Early Start Denver Model (ESDM) for treating young children with autism.


To be enrolled in the program, your child must first have a comprehensive evaluation that includes the ESDM Checklist. Our team will assess your child’s current level of functioning in the following areas:

  • Receptive and expressive language
  • Joint attention
  • Problem-solving
  • Play
  • Gross motor and fine motor
  • Behavior
  • Daily living skills

Using the results of this evaluation, our team will develop therapeutic goals and objectives for your child.

Program Details

During your child’s 3.5 hours of daily program time, he or she will participate in one-on-one therapies as well as group interventions. The therapies are delivered by:

  • Speech/language pathologist
  • Occupational therapist
  • Registered behavior technician
  • Board-certified behavior analyst

Children in the Intensive Early Intervention Program are offered inclusive opportunities with peers each day during outdoor and/or gross motor play. This will be expanded as your child reaches certain milestones in the program.

Participants meet four half days per week on the campus of Mercy Hospital St. Louis, 615 S. New Ballas Rd., St. Louis, MO.
