Welcome! If you’re here, you’re looking for a copyeditor, fact-checker, researcher, or a copywriter. You’ve come to the right place!

As trained editor and a former litigator, I’m skilled in identifying critical elements of a story and evaluating them for accuracy and effectiveness. As an editor and former litigator, I know just how important it is to find the right words to match your audience.

What is more, I have listened closely to the words and voices of people from all walks of life, so I can assist you in making sure that your characters sound believable. This is important for fiction and for history. I also know how important it is to you that your manuscript look polished and professional, with correct and consistent spelling, grammar, usage, and punctuation.

I have years of experience in understanding forensic and scientific evidence well enough to communicate it to people of all educational levels and backgrounds. I have learned to distill the most important facts and parts of the story. I know how to organize evidence and narrative into a coherent and powerful manuscript.

I have published in comparative literature, psychobiology, psychological anthropology, and law. I have prepared panel discussions on healthcare policy in the United States. I’m a subject matter expert in special education law.

I have an editing certificate from the University of California Berkeley, a JD from William and Mary Law School, and a BA in comparative literature from the University of Virginia.

I specialize in humanities, social sciences, law, forensic science, behavioral health, medicine, and history, as well as memoirs/autobiographies, YA, apocalyptic fiction, science fiction, literary fiction, and fantasy. Services I provide include copyediting, structural editing, line editing, developmental editing, fact-checking, research, ghostwriting, and flagging or fixing of plot holes.

I know how important it is for your editor to strengthen your voice and to respect your material. It is not easy to hand over something you’ve worked so hard to create to a relative stranger. I work with professionalism and tact. I look forward to working with you.
