I've been studying private lessons with Kru Jan for almost 2 years.
Before studying with her I understood a little Thai, but I really struggled with both tones and vowel sounds. I also could not read Thai script at all.
Kru Jan was able to very quickly and effectively correct all of my bad habits, improve my pronunciation, and also improve my tone. Additionally, she had me reading faster than I ever thought would be possible!
Kru Jan always pushes my limits and challenges me to work hard and improve my Thai in all areas. She is really focussed on helping me achieve my full potential and any compliment I ever receive with regards to my ability to read, write or speak Thai can be directly attributed to her.
