I specialize in developing and editing English-language materials for individuals and companies competing in a global economy. As an editor with over 12 years of experience working on scientific papers, research articles, ESL books, and tour scripts, I have a solid understanding of the correct presentation of a wide variety of material. I am the co-author of two writing guides, and I developed a series of English readers for elementary school students (this series is still in use). I am currently developing ESL workbooks for a respected publishing company. I have been a part-time ESL teacher and tutor for about ten years, so I understand the challenges non-native speakers face.
