Hello. I do know of an ABA group called the Center for Behavioral Sciences that has therapists that speak Korean and Mandarin. I think they are based in Irvine but they do have a training center in San Diego, so maybe you could find someone there.
Thank you!! Just checked the site (mi piace!). I checked the web and there seems to be one Korean behavioral analysis (Eric Ha). I will see if I can talk to him. Thanks. Kay
