Jessica Hammerman – Editor

Editor, historian, professor. Here to help you take your book to the next level. Whether fiction or non-fiction, I can help find your voice.


I'm a detailed editor who worked in publishing for over 20 years. I have a PhD in history. I've helped hundreds of writers, and would love to help you too. I've seen a book transform from average to outstanding, and we've had a few breakaways in the top of their categories on Amazon, including historical fiction, how-to or business books, memoirs, and fantasy.

Now booking new projects for Summer 2024!



"This was my first time writing on a subject that was very personal to me.... Jessica was very patient and supportive on my efforts and rewrites. I do believe her encouragement, editing recommendations, and critiques truly were instrumental in bringing the story to another level. Her professionalism and broad knowledge of the art of storytelling was a tremendous asset and I would highly recommend her for your next project."


"As a business writer, I was delighted to work with someone who understood the voice I wanted in the final product. Her knowledge of APA and citation gave me confidence that my work would be viewed as thoughtful, thorough and credible. Editors are critical team members in this demanding process, and the additional depth Jessica brought beyond the standard editing process of grammar, format, and voice added much value to the work. Highly recommended."


"Jessica put me at ease and explained clearly the process and the pricing. When completed, there were no surprises. Jessica worked with me on editing with suggestions and punctuation. She made my words into a real story!"


"This was my first experience with a professional editor, and everything went better than anything I could have planned for. I’ve had friends tell me horror stories... But I have to say that this was worth every dime. Jessica not only helped me cut back on my word count, but she gave me great and helpful tips on how to improve my story. Her feedback was positive and motivated me to keep working. I found the task of editing my book daunting, but Jessica eased my worry and made the process extremely easy. There’s no smoke and mirrors here. I got more than what I paid for and I can’t wait to move forward with publishing my book."


"Dr. Jessica H. was the editor of my first novel. I’m not college educated and this is my first attempt at writing for an audience other than myself, so when I learned of the extent of Jessica’s education and experience I was really quite intimidated. My experience with Jessica has been far from intimidating. Her criticism has been constructive and every one of her edits have added nothing but quality to the finished product. I actually recommend Jessica’s services because she became more of a writing coach than just an editor. I’ll definitely be using her advice, tips and suggestions in all of my future work."
