    Thank you for your interest! I am out on maternity leave until at least the first week in May and will not review any new offers until after that time. Sorry for any inconvenience. Need compelling copy? Know what you want to tell people, but have no idea how to do it? Let me help! I have spent over a decade working one-on-one with individuals and companies with the goal of creating and refining written works of all lengths and for a variety of media. My success lies in my intimate knowledge of both the English language and its use in marketing and communication. I believe that careful thought should go into all written work and have perfected the ability to help make the ideas of others into eloquent prose. I have advanced research skills that allow me to not only write about, but get to know your industry or company as if I had been there from Day 1. My goal is to work both collaboratively with my clients as well as independently of them in order to meet the needs and demands of writing and editing projects for their company.
