I have 30+ years experience teaching English, specializing in preparing students to write for college. As a bit of a grammar nerd, I enjoy exploring the relationship of words and the structure of sentences. I cringe when communication is hampered by careless wording and a refusal to follow the rules of punctuation and usage. If you think it is okay to omit the comma before the conjunction in a series, you do not want me to proofread your writing.&nbsp;<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Having read and critiqued thousands of student essays, hundreds of professional communications, and dozens of official documents, I do not miss errors in grammar, usage, mechanics, or sentence structure. In addition, I practice conservation of words, making your writing clearer, more concise, and more effective.
