I am a freelance non-fiction editor who specializes in helping small businesses and individuals grow through self-publishing. I do everything from developmental editing to copy editing and print formatting. My focus is on helping you offer the best value to anyone who picks up your book.

Getting your non-fiction book published can be great for business, your personal brand, or achieving a life-long goal. The rise of self-publishing makes it easier to get your book in your readers’ hands or on their devices, but the quality of your book is where you’ll really stand out.

As an experienced editor and avid reader myself, I truly understand how non-fiction books work — how they’re structured, which questions they should answer, and how readers read them. This gives me a unique perspective on your book and how we can work together to create a product that will not only interest your target audience but bring in new clients and grow your business.

I can walk you through the process of self-publishing from start to finish. I know more than most about self-publishing, especially the technologies used and the print and distribution options available to you. I work with all skill levels, including people who have no idea where to start. In fact, walking you through your options is my specialty.

If you’re new to self-publishing or an old pro, I can help you make self-publishing your book a breeze.

Don’t take my word for it. Here are a few comments from past clients:

“Gillian is incredible! I could tell that she really cared about my project and spent the time to understand exactly what I wanted and then overdelivered. I'll definitely be using again! — Danny J.

Fabulous to work with. I had no idea of how the editing and publishing process worked. She provided me with step by step guides and gave me choices and made the process very easy. She also challenged me in my writing, more than I expected and this made for a better product. Would definitely recommend.” — Renee K.

“Gillian was AMAZING! She helped me with my first book from start to finish. She was an excellent and timely proofreader/editor; she designed the book cover art and formatted the manuscript for CreateSpace to publish as a real paperback book on Amazon and Kindle. Thank you, Gillian!” — Stacy T.

I hold a post-graduate certificate in Technical Writing from Algonquin College, have participated in SFU’s editing certificate program, and hold a BA in Political Science and Global Studies from Wilfrid Laurier University.

I also write about self-publishing and provide free resources through my website, Reach out to me by email to tell me about your project and get a no-obligation estimate for your non-fiction book.
