Mill Creek - Pediatric Therapy

IRG Cascade Children's Therapy - Mill Creek

IRG Cascade Children’s Therapy - Mill Creek was opened in 1989 by Claudia Andrews, Janine Czerniecki, Vicki Schwartz and Linda Wishkoski. As a multi-disciplinary clinic offering occupational, physical and speech therapy, we strive to optimize the health and participation in home and community life of children from birth through adolescence. 

We serve families in Snohomish, King and other surrounding counties. Our clinic primarily treats neuromuscular conditions, genetic syndromes and other developmental delay concerns. These include, but are not limited to:

  • Autism spectrum disorder
  • Brachial plexus injury
  • Cancer
  • Cerebral palsy
  • Down syndrome (Trisomy 21)
  • Language delay
  • Sensory processing disorder
  • Apraxia of speech
  • Traumatic brain injuries
Wondering if you need a referral from your child's doctor to start treatment? Washington is a direct-access state, meaning that you can start physical or speech therapy without one in hand for most insurances.
Can't make it into the clinic? IRG Cascade Children's Therapy - Mill Creek offers telemedicine appointments. Give us a call at 425.338.9005 for more information.
