Work experience


Feb, 2018 — Present

Using my 12+ years of experience as the managing editor for an independent press, I have now launched my personal freelance editing, proofreading, and writing business. At the press, I have edited over a hundred full-length manuscripts for successful publication. I have edited in all genres within fiction and nonfiction categories, and I have worked with veteran authors and first-timers alike. I am excited to bring my professional publishing experience into my new freelance endeavor, and I look forward to working with you!

Sunbury Press

Jan, 2011 — Jul, 2023 (over 12 years)

At Sunbury Press, I liaised with new and established authors, as well as with publicists, cover artists, book designers, agents, marketers, social media directors, bloggers, reviewers, interns, bookstores, distributors, and writing communities. I performed all tasks in the book editing process—including preliminary review, developmental/content edits, line edits, proofs, and extraneous editing for supplementary documents.

(NOTE: The Portfolio section contains just a small sampling of the 100+ books I’ve professionally edited and/or proofread for Sunbury Press and its imprints throughout my publishing career.)
