If you have a document relating to the  fields of medicine or science that you need to sound polished and "natural", for example prior to submission to a medical journal, I can help.  I am a qualified USA-born veterinarian with 5 years of experience reading and writing journal-quality articles.  I pledge to work with you until you are 100% satisfied with your documents, and quality is of utmost importance to me.  If you have a specific time limit, whether hours or days, please let me know, as I am flexible.  I will also attempt to improve any document, even those outside my specific field.
