I've run an editing business since 2020 and worked on more than one hundred books, mostly nonfiction, for traditional publishers and self-publishing authors in that time. Before that I was a newspaper journalist for twenty years, writing and editing articles on a wide range of topics.

I'm highly knowledgeable about the nuts and bolts of editing — grammar, punctuation, style guides — and I'm consistently thorough (including basic fact checking), sensitive to the author's priorities, and committed to helping them make their work the best it can be.

I mainly do copyediting and proofreading, but I'm also available for substantive editing — or a customizable mix, depending on the author's needs. I also offer competitive rates and friendly, prompt service.
