Englishworks, Inc. is a private school that primarily teaches English to non-native speakers. However, they also provide writing services, such as editing, proofreading, and assisting in resume writing. They also offer preparation for most of the standardized tests for high school and college, such as the SAT. They work with both individuals and corporate clients and are very flexible, in terms of serving a particular customer's needs. They have very good teachers and they are also highly qualified. They are by far better than places like Sylvan or Berlitz, where there is not a requirement that instructors have degrees in English (or at all, in some cases). After checking out Sylvan and similar competitors, the superior quality of Englishworks became clear--Sylvan just has their students fill out worksheets while someone "babysits," and Berlitz uses a similarly ineffective technique. I highly recommend this school.
