Korean Translators in Massachusetts

I am fluent in both English and Korean, but English is my strongest language. I am half-Korean and half-American and I grew up in a South Korean community in a culturally Korean part of China. To be brutally honest, my Korean language level (speaking, writing, reading, listening) is similar to that of the typical Korean middle school student. My English is as good as any other American. I learned Mandarin Chinese for more than ten years. My Chinese language level is very advanced.
