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

In 2013, I left the legal profession, where I was a trial lawyer, to become an editor. I have a special needs child, and working at home made the most sense. I’m still licensed to practice law in Virginia and in Arizona.

I am a polymath, knowledgeable in a wide range of subjects and disciplines. I have published my own articles in legal textbooks and law, social sciences in medicine, psychoanalytic anthropology, and literature journals, even though my bachelor’s degree is in comparative literature.

As an editor and copywriter, I use the same skills I used as a lawyer. I help fiction writers tell their stories and I help scholars and other professionals present their evidence. Of course I can help with grammar, mechanics, spelling, and punctuation, but I also can help with things like fact-checking, research, ghostwriting, and flagging plot holes.

I work with both fiction and nonfiction. As a former prosecutor who has extensive martial arts training–including with firearms–I’m uniquely qualified to edit your police procedurals. I also edit autobiography and memoirs, YA, thrillers, science fiction, speculative fiction, and fantasy. The subject matter experience I gained in criminal law and child welfare law makes me just the editor for your behavioral health, medical, and forensics work.

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. Integrity is at the core of all I do. I look forward to working with you.
