Speech, Language & Communication Services

What We Do | Speech Community Cares Fund | Continuing Education | Client Forms | Resources | Contact | Staff

HSDC’s Speech department works with community members of all ages who experience a variety of speech-language differences. 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. Medicaid and other forms of low-income insurance do 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. 100% of contributions to the fund support the delivery of speech and language services to children and families who need financial assistance. It is supported primarily by other local Speech-Language Pathologists and service providers, but we welcome donations from all.

As of late 2018, we have delivered over 4,000 speech and language therapy sessions in the past 5 years for Medicaid clients. We believe the Speech Community Cares Fund may potentially double that number. 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, complete the form on our Donate page and put a note in the “Leave a comment field” that says “Speech Community Cares Fund”.
