Joanna has an incredible ability to elevate a manuscript while also supporting the author through the entire publishing journey.

“I had the incredible luck to work with Joanna Ng as the editor of my first two books at Penguin Random House. Joanna’s winsome personality and enthusiasm for my writing made me so comfortable. She provided clarifying questions, made important suggestions for organization, and offered skillful edits for tricky passages. My books were expertly managed from drafting to polishing. Joanna is also great at honoring the time frames she sets for providing that feedback. I hope I get to work with her again someday.”

“Working with Joanna on A Place to Belong was a true gift. She brought a rare combination of precision and warmth to the editing process—making specific recommendations while also encouraging my authentic voice to shine through. Her feedback was always thoughtful, clear, actionable, and culturally relevant. I felt fully supported from start to finish. She's not only an excellent editor but also a true collaborator, and I’m deeply grateful for the role she played in shaping my book.”

—Amber O’Neal Johnston, author of A Place to Belong

“Joanna Ng is a talented editor who can help bring out the best in your writing! I was so pleased with the quality of the feedback she gave on my manuscript. My own background is primarily in scientific writing, and Joanna did a great job helping me identify places where I was over-explaining or using needlessly complex language. She has a wonderful capacity to identify the main messages of a chapter or a story and keep the focus on what supports those messages. She also went over and above my expectations by staying involved in the editorial process throughout the manuscript’s path through both my U.S. and U.K. publishers. I felt her investment in producing the strongest manuscript every step of the way. Would definitely engage her again!”

—Sherry Hamby, PhD, author of Stronger Than You Think
