What Hearing, Speech & Deafness Center does
Hearing, Speech & Deaf Center (HSDC) is a 1937-founded nonprofit resource hub headquartered in Seattle, Washington, operating three regional offices (Seattle, Tacoma, Bellingham) and serving 13 counties in Western Washington. The organization delivers a multi-disciplinary service portfolio spanning clinical care (speech-language pathology, audiology), ASL interpreting coordination, deaf and hard of hearing case management and advocacy, and bilingual ASL/English early childhood education through two named sub-brand programs: the free Parent-Infant Program (PIP) for children ages 0–3 and Rosen Family Preschool (ages 0–5), the only fully immersive ASL/English classroom in King County. The technology and methodological backbone is a bilingual/bicultural service delivery model combining American Sign Language and English, supplemented by a virtual service delivery platform established during COVID-19 that enables remote interpreting, speech therapy, and family support.
Revenue mechanics reflect a hybrid nonprofit model. Core community programs (PIP and Deaf & Hard of Hearing Services) are provided free of charge to eligible households and are funded by donations, grants, and fundraising campaigns including GiveBIG, end-of-year appeals, and online donations through the Zeffy platform. Earned revenue comes from fee-for-service ASL interpreting coordination and organizational training (e.g., Deaf Culture and workplace accessibility training delivered to employers such as Safeway), supplemented by meeting space rentals and an assistive listening technology loan program. Distribution is conducted through direct in-person service at the three offices, in-home visits for early intervention, on-site organizational training, and virtual channels. The customer mix is dominated by individual families and Deaf/hard of hearing adults served through case management, with a smaller enterprise training segment.
The organization is led by a Co-Executive Director model (Ariele Belo and Lindsay Klarman) since November 2022, with Klarman announcing her departure in March 2026 and Allie Rice named as incoming Executive Director effective June 8, 2026. There is no parent company, no outside equity, and no disclosed financial figures; the organization is governed by a board including executives from BECU, FedEx, and Discover Live.

- Listen and Talk: Seattle-based nonprofit serving DHH children with auditory-verbal and speech-language therapy. As a direct local competitor for early intervention services, it is one of HSDC's closest geographic and mission-aligned peers.
- Hearing Loss Association of America (HLAA): National nonprofit providing information, education, advocacy, and support for people with hearing loss. Comparable advocacy and case-management mission, though operating at national scale rather than regional.
