Occupational Therapists (OT)
OT center:
My 9 year old son has attended occupational therapy at SISO in Mapo for 1.5 years. He is in a weekly social skills group, paired with one English speaking child the same age and an English speaking therapist, for 70 minutes. The sessions are fun for the kids and the therapy has been helpful for my son in improving his social skills and gaining confidence. The office took whatever measures were needed to become a Tricare provider for me.

Travel therapist:
My son has also worked with a travel therapist, who visited his international school once a week as the school did not have one on staff. She is knowledgeable with working with neurodiverse children and is communicative over text and email. She also works in a clinic setting and is a PhD candidate, so has limited availability. She is familiar with NDSP funding and charges 100,000 won/hour.
Here is another travel therapist that I did not end up hiring because she works full-time at an international school and was only available afterschool. But I heard she has come on base to work with other embassy families.
