My name is Catherine. As a trained copy editor and proofreader, my aim is to make sure your sentences flow smoothly, free from any distracting inconsistencies, awkward phrasing, or repetition. I’ll also check for correct punctuation, spelling, and grammar, so you can publish and share with confidence.

I specialize in nonfiction books, website content, online course material, blog posts, and email newsletters.

My favorite genres to edit are true crime, entrepreneurship, online business, and self-help. 

Whether your document needs a sentence-level edit or a final check, I will provide a thorough and reliable service.

I’d love to discuss your project to discover how I can help you. Let’s talk!

Catherine Turner proofreader and copy editor



  • Catherine’s work is professional, thorough, detailed and prompt. I was delighted by her work on my book. Not only did she edit my copy beautifully, but she went the extra mile of checking my quotes and double checking my facts. I will not hesitate to use her again and recommend her enthusiastically to others!

  • I have worked with Catherine over many years in the delivery of written outputs for the Central Bank of Ireland. At all times, Catherine’s hard-work and reliability have shone through and her thoroughness and efficiency have added real value for the team.

  • Catherine’s work on my book was the fine coat of finishing polish that every author should give their book before publishing. Her work is thoughtfully professional, thorough and raises the bar for my next level of self-editing. Highly recommend her services to anyone writing and publishing work for the world to see. Even on my worst review, the reviewer had to compliment the writing and the editing- which most certainly includes that final spit shine provided by Catherine. Always a pleasure to work with!

    – Juanita Renee Jones, Author of The Multi-Passionate Entrepreneur’s Playbook

  • I hired Catherine to proofread my new general proofreading course. (Yes, even a course on proofreading needs proofreaders!) Catherine’s eagle eye for tricky typos combined with her professionalism and excellent communication skills made her a true pleasure to work with. I will keep her in mind for future projects myself, and I definitely recommend Catherine to content creators who need any general proofreading work done.

  • Catherine is extremely thorough and detailed with her work. You know your project is in good hands with her at all times. She communicates regularly, is always open to questions and you never have to worry about her meeting your deadlines. I’ve had colleagues comment on how they couldn’t find a single typo or grammatical error when they read through my book. I’m so happy I found her and see her as a valuable part of my team.

  • I have enjoyed working with Catherine, not only because of her professionalism, but you can tell she cares about your project (which is very important for me when picking people to work with). She delivers work to you fast and is always ready for any challenge you send her way. I had never worked with a proofreader before Catherine, but she made my first experience pretty amazing, and I don’t see myself working with anyone else.

  • As an author, I have hired several editors, and Catherine by far has been the best to work with. She is dependable, extremely detailed, friendly, and professional. She goes the extra mile to make sure your work is top notch and responds quickly to any questions you have. Catherine is a pleasure to work with, and I highly recommend her!

  • Catherine has been a life saver for me and my journey of writing my book. I felt stuck in my fear and the process of writing my book, and Catherine calmed my fears by giving a clear road map of how things were going to come together. She was patient with me as I worked to articulate my thoughts and feelings. My work was always returned in a timely manner, and the suggestions were presented in the spirit of respect and encouragement. Thank you, Catherine, for helping me share my story and making my lifelong dream of publishing a book possible.

  • Here at Slingshot Books, we are so glad we found Catherine! She has been our go-to proofreader for our Dead True Crime book series and has never let us down. She’s professional, easy to work with, and has done a truly fantastic job at cleaning up our books for publication. Catherine has an eagle eye for grammatical errors, misspellings, inconsistencies, and all those annoying mistakes you thought you caught, but didn’t. She makes you look good. Do yourself and your manuscript a favor: hire her!
