Hamaguchi & Associates Pediatric Speech-Language Pathologists, Inc. is a professional corporation dedicated to providing private speech-language therapy for children in a warm and loving environment. We've been in Cupertino since 1996! We take pride in being a model of “best practices” in the field of speech-language pathology, utilizing state-of-the-art methods, tests, training, and materials. Our licensed speech-language pathologists are passionate about working with children, and all hold a Master’s Degree in Speech-Language Pathology or Communication Disorders, are licensed in the state of California and members of the American Speech-Language Hearing Association. Our office is child-friendly, complete with toys, puppets, videos, games and specialized software. We offer assessments, as well as individual or group therapy sessions for children up to age 12.

We are now scheduling for our 2019-2020 academic year program.  We are no longer able to offer individual sessions after 2pm as these are all taken.
