  No matter who your readers are, your content needs to be clear, accurate, accessible, and engaging. I can help.

An editorial professional for almost 2 decades, I've helped clients with projects like the following:

✔️ Consumer health and patient education materials
✔️ Educational and marketing content
✔️ Web copy, blog posts, and newsletters
✔️ Magazine articles and annual reports
✔️ Social media content and infographics

Throughout my work, I put myself in your readers’ shoes. I focus on the structure, tone, words, mechanics, and cultural context of your message so that it shines when it reaches your audience.

I hold an editing certificate from the University of California Berkeley Extension as well as the ACES/Poynter Certificate in Editing. I’ve done extensive training in Chicago, AP, and AMA styles. And I take advantage of every opportunity to learn more about effective communication, attending webinars on inclusive language, plain language, literacy, accessibility, AI, and other topics.
