Jen Z. Marshall – Editor

Experienced educator-turned-editor with expertise in developmental and copy editing. Well-versed in traditional and independent publishing.

Overview

I have professionally worked on over 100 published books, providing developmental, line, and copy editing services and initial assessments to both traditional and independent publishers. My passion lies in helping authors inspire meaningful change for students and educators. I can support writers throughout the process, from providing valuable feedback on their initial drafts to preparing a manuscript for the final publication stages. My primary objective is to help specialists convey their information in a style that is accessible to their demographic, ensuring their wisdom reaches a wider audience while maintaining integrity.

I collaborate closely with authors, utilizing my publishing proficiency and industry knowledge to help them improve how they express their mastery and insights. As a former teacher, I understand the practical aspects of classrooms and schools, which enables me to offer real-world advice and support. Through guidance on structure, tone, and style, I empower authors to effectively communicate their expertise, enhancing the impact and influence of their books. While I typically follow the guidelines set by the Chicago Manual of Style, I am flexible and accommodating to preferences, working diligently to preserve unique styles and voices.
