We visited 3 schools - Little Village, ABC Learning Center, and Silliman. Talked to some teachers and looked at the facilities. Of the 3, Silliman seemed to be our favorite but ABC is also a possibility. I did not visit the Montessori one but I saw the sign off the highway as I was driving in so we'll check that next time. I had emailed One International and set up an appt to see the school but the head of the school never emailed me back to confirm, even emailed her a couple more times and never got a reply again. Very odd.
UPDATE: I received an email today from Jenny, the Head Teacher at One International, and she forwarded me the email she had sent on the 11th confirming my visit and giving directions to her school. I have no idea why I never got it but my apologies to Jenny. I will visit One International on my next visit.
