Actually the Andrew Biggs Academy (which really specializes in teaching Thais English) also has a teach foreigners Thai class too.

I think (although I'm not sure) I reviewed them briefly before. I did go to the school and look at the books, which were really well put together and written by a Thai who specializes in teaching Thai to non-native speakers.

If I remember correctly they don't offer group classes but do teach 1 on 1 private lessons.

That series Andrew has called "Tongue Thai'd" is a good thing to watch. Here's his website link with 25 episodes on it ;
Andrew Biggs Academy Tongue Thai'd

and here's a Women Learn Thai You Tube link with 40 episodes;
WLT Tongue Thai'd Andrew


There are TONZ of good learning Thai resources on You Tube if you look around.

I’m still of the mind that as a beginner you don't need to frontload the huge amount of time it takes learning to read Thai to be able to speak understandable Thai, but that's just me I guess...

Good luck however you go about learning the language...
