Ellen Kester Founder of Bilinguistics Speech Therapy Clinic

Ellen Kester

Ph.D., CCC-SLP, President

Speech Language Pathologist

Dr. Kester founded Bilinguistics to meet the speech and language needs of children from diverse backgrounds. She provides workshops around the United States and beyond on bilingualism, assessment of bilingual students, and effective intervention practices. Dr. Kester periodically teaches courses at The University of Texas at Austin in language development, assessment and intervention, early childhood intervention, preschoolers with special needs, and measurement. Her research and clinical work address the important issue of differentiating bilingual children with typical development from those with language impairment, and identifying appropriate goals for intervention with bilinguals.

Ellen’s passion for languages started when she lived in Asia as a teenager.  She learned to speak a little Malay and Mandarin and studied French while in Asia.  She then returned to Texas several years later and decided Spanish would be more useful.  She dove into the world of bilingual assessments in graduate school and that continues to be her passion in the field of speech-language pathology.  When she’s not working, she loves being on the tennis court or traveling with her husband and three children.
