Hi Joanne
Yes I think the nearest ST clinic to Tung Chung is probaly in Central. I am a speech therapist working for the Rainbow Project which is a charitable organization in HK set up by a group of English-speaking parents in Hong Kong in 1999. We have classes for kids with autism in the Sunshine Preparatory House in Tung Chung. I need to go there once a week to provide speech therapy to the kids there at our class. Might be I can go to your cousin's home to provide outreach ST training to your cousin's son as well afterwards. Pls kindly visit
www.rainbowproject.org for further details or phone me by 2548 7123. Hope I can help you!!
