I am a dynamic and proven editor specializing in the humanities and social sciences, literary fiction and short stories, and business materials. Services offered include proofreading, copy editing, manuscript evaluations, writing and rewriting, and index and reference checks. I am happy to say that in April of 2017 I received notice I had earned my proofreading certification through Editors Canada.

As an editor, my goal is to bring out the best in my client’s work, always respecting an individual’s voice and style. Throughout my career I have developed a reputation as reliable and self-directed, with a sharp eye for detail. My past experiences include editing marketing materials and emails, plays and short stories, academic text supplements, and novels for independent authors. I have also edited essays for students, as well as posts for established bloggers.


I graduated from Trent University with an Honours Bachelor of Arts in English Literature & Language, with a minor in History. From there, it was a natural transition into the world of publishing and I got my feet wet as an editorial assistant for an academic publisher. In 2009 I pursued a certificate in Creative Book Publishing from Humber College, and have since worked for numerous publishers and authors.

My experience has given me familiarity with the publishing process, as well as with editing best practices, grammar, copy editing and proofreading marks, and on-screen editing with Microsoft Word and Adobe Acrobat. Not one to rest on my laurels, I continually seek new learning opportunities through various courses, seminars, and webinars.

What else should you know about me?

Well, reading and writing have been my lifelong passions, and I spent my childhood devouring, creating, and acting out stories. The best part is that I still get to do so as an adult!

When not working with clients, I enjoy reading (especially literary fiction), writing, painting, going on long runs with my dog, and spending time with family and friends.


"Jennifer is a consistent and detailed editor. She is a consummate professional and communicates well with authors and publishers alike. Her queries to authors are considered and well-formed, and she picks up on changes a less-experienced editor would overlook. Jennifer is the first person I call when I'm in need of freelance editorial work." - Blake Sproule, Editor at Playwrights Canada Press

"I really appreciated the fact that Jennifer communicated with me! I felt she constantly gave me the feedback I needed, that challenged me, and that has definitely helped my writing!" - Rob Russell, Writer
