Speech, Language & Communication Services

HSDC’s Speech department works with community members of all ages who experience a variety of communication challenges. Our goal is to remove communication barriers by offering services tailored to meet the needs of our clients. We support and educate the client and their families/caregivers, while also collaborating with other health professionals to help them communicate more effectively in their everyday life.

We provide diagnostic evaluations, as well as individual and small group therapy in the following areas:

  • Receptive and expressive language disorders
  • Auditory processing disorders
  • Speech sound disorders
  • Motor speech disorders
  • Aural (re)habilitation
  • Stuttering
  • Literacy development
  • Augmentative and alternative communication (AAC)
  • Feeding/swallowing disorders
  • Gender voice therapy

If you’d like to discuss what evaluation or treatment options may be right for you or your child, please contact us today.

Speech Community Cares Fund

For over eighty years, HSDC has provided excellent communication care to families, regardless of their ability to pay. This is a challenging time in healthcare, and Medicaid does not support speech therapy services that give vulnerable children the care they deserve. We are committed to providing this life-changing treatment, but we need your help.

HSDC created the Speech Community Cares Fund to increase the number of low income children our speech therapists in Seattle can serve each day. We have delivered over 4,000 speech and language therapy sessions in the past 5 years for Medicaid clients, and we believe this fund may potentially double that number.

100% of contributions to the Speech Community Cares Fund support the delivery of speech and language services to children with Medicaid. The fund is supported primarily by other local Speech-Language Pathologists and service providers, but we welcome donations from all.

Just $168/month bridges the gap between the cost of weekly speech therapy for one child and the amount of Medicaid reimbursement HSDC receives for those services.

To contribute to the fund, fill out the form on our Donate page and put a note in the “Leave a comment field” that says “Speech Community Cares Fund”.

Speech Community Cares Fund Badge Service providers that pledge to the fund will receive this badge for their website.
