You exceed my expectations. Not only did you correct the English in my dissertation, you did so while being ever mindful of the variety of subtle differences in language use between academic fields. You were able to expertly navigate between English errors that could just be corrected and English errors that required flagging for clarification and where the most obvious English correction would changed the content of my dissertation. The end result was a PhD dissertation which was not only written in proper English but had much clearer content as well. You were willing to go beyond expectations when editing my PhD dissertation.
