Catherine Knepper

I help writers, experts, and leaders turn complex ideas into books that matter.

For over twenty years, I’ve worked with people who have something vital to say and need a skilled partner to help them say it well. Whether you’re distilling decades of professional insight, uncovering the emotional truth of a story, or translating specialized knowledge for broader audiences, great books require both craft and clarity. My job is to help you achieve both.

I’ve collaborated on fifteen books, including USA Today and Wall Street Journal bestsellers, Thinkers50 selections, Next Big Idea Club picks, Financial Timesbest-of books, and Axiom Award winners.

My editing clients include National Book Award finalists, multiple New York Times bestsellers and Notable Books authors, PEN Award winners, Independent Publisher Book Award recipients, and writers whose work has been named among the year’s best by Time, Entertainment Weekly, and NPR’s Fresh Air. Their books have earned starred reviews from Kirkus, Library Journal, Booklist, and Publisher’s Weekly—and landed on reading lists from President Barack Obama to Malcolm Gladwell.

I also develop book proposals that are as carefully crafted as the books they promise. Every proposal I’ve written has sold to a major publisher.

More About Me

I began editing in 2003 while completing my MFA at the Iowa Writers’ Workshop. The Workshop taught me a great deal about the creative side of writing, but it was working as an editor and collaborative writer that taught me the business of publishing—how to position a book, how agents and editors think, how to navigate the distance between a brilliant idea and a manuscript that actually sells.

Since launching my business in 2009, I’ve worked with hundreds of authors across dozens of genres, collaborated on fifteen books, and developed proposals for major publishers. I’ve cultivated working relationships with many of the top literary agents in the business and written everything from speeches and op-eds to book marketing materials. My fiction has appeared in West Branch, The Florida Review, Memorious, Necessary Fiction, Meridian, Confrontation, and The Maine Review.

My degrees span English literature and philosophy & religion (B.A.), theology (M.Div.), and fiction (MFA)—a multidisciplinary foundation that informs how I think about structure, argument, and narrative across genres. As a writer with experience on both sides of the publishing desk, I’m in a unique position to help you make your book both beautifully crafted and commercially successful.

Testimonials

Catherine served as a fabulous, much-needed second reader on my (rather long and complicated) novel, Cloud Cuckoo Land. She helped me tighten language, repair chronological wrinkles, clarify muddled passages, and even invent some terminology. And she served as an essential sounding board for all sorts of revision ideas. Most importantly, Catherine helped me stay confident and buoyant when I was exhausted from the work of assembling the book. I wholeheartedly recommend her services.
Anthony Doerr, Pulitzer-prize-winning author of the novels Cloud Cuckoo Land and All the Light We Cannot See
Writing a book can feel very lonely. Catherine was the ultimate companion on the journey and made it feel far less so. It was important to me to have someone who could coach me through the process—someone who truly got me, my voice, my intent, and my message, and who was willing to challenge me, push me, and sharpen my thinking and writing along the way. Catherine was all of that and more. Her ability to help you get out of your own “lost in translation” moments is uncanny. I’ve told her once and I’ll say it again: she’s stuck with me!
Muriel M. Wilkins, CEO of Paravis Partners, host of the Coaching Real Leaders podcast, bestselling author of Leadership Unblocked: Break Through the Beliefs that Limit Your Potential and Own The Room: Discover Your Signature Voice to Master Your Leadership Presence
Catherine Knepper has a rare gift for finding your voice before you've fully found it yourself. She brought patience, creativity, and razor-sharp attention to detail to every page of Burnout Immunity, pushing my ideas further while keeping them authentically mine. But what I appreciate most is how much fun she makes the process—collaborating with Catherine feels less like work and more like the best kind of creative partnership. I'm thrilled to be working with her again on my second book.
Kandi Wiens, Ed.D., Senior Fellow at the University of Pennsylvania Graduate School of Education and bestselling author of Burnout Immunity: How Emotional Intelligence Can Help You Build Resilience and Heal Your Relationship with Work
There are editors, and there are editors. And then—I kid you not—there are editors. I’ve worked with a lot of editors. All kinds. Heck, I’m an editor. Catherine Knepper is damn near peerless. Fiction or nonfiction; it matters not. She’s the kind of editor that editors want to work on their prose. It won’t be easy to get on her schedule but if you get the chance, grab it with both hands and hold on for a wild ride.
Wesley Wildman, Ph.D., Executive Director of the Center for Mind and Culture, professor of philosophy, theology, and ethics at Boston University, and co-author of Spirit Tech: The Brave New World of Consciousness Hacking and Enlightenment Engineering
Catherine is truly lovely to work with. She immediately made me feel very comfortable, making it easy to share my story. She immersed herself in my personal journey, and her ability to take my life and put it down on paper in a way that is completely authentic and genuine is so impressive. She captured my voice and translated it to a story that reads so beautifully—exactly what I wanted to say, but better.
Suzi Weiss-Fischmann, co-founder and brand ambassador of OPI Products, Inc. and author of I’m Not Really a Waitress: How One Woman Took Over the Beauty Industry One Color at a Time
Catherine Knepper isn’t just an editor—she’s a true writing partner. She takes the time to really understand a writer’s voice, vision, and goals, and works alongside them to bring out the very best version of the book. She never tries to impose her own agenda; instead, she helps you make the work unmistakably yours. When the process calls for big, even seismic decisions about content, Catherine has a rare ability to guide you through them with clarity, confidence, and care.
Jeffrey L. Goodman, Founder of Goodman/Keller P.C. and Harbinger Jury Consultants, Inc., and curator of The Book of Judges: Perspectives from the Bench
As a second-time author working with Harvard Business Review Press, I knew I needed someone who could deliver a high-quality, no nonsense, practical manuscript for a business audience and be able to do that in a way which also captured my natural style, authenticity, and voice as an executive coach. From the outset, I noticed Catherine’s rigor in how she approached really understanding the publisher I was working with and the reader I was writing for. Her level of commitment only continued as we spent months working together to transform outlines, drafts, research, and interviews into a fully realized manuscript. Catherine is a gifted writer and fully brought to life my voice and message. On top of producing an outstanding, quality end product, Catherine is an absolute joy to work with! She is authentic, positive, and encouraging all along the way, which offers an author a sense of important ease during a process which can bring high stress and tight deadlines.
Amy Jen Su, Co-Founder of Paravis Partners and author of The Leader You Want to Be: Five Essential Principles for Bringing Out Your Best Self—Every Day
I have no doubt my book would not have been the success it is without Catherine’s editorial help. This was a challenging piece and I had fast deadlines, but she immediately understood my objectives and voice, and was able to quickly identify smart solutions on exactly how to move it forward. She breathed new vision into my manuscript in just a few short weeks. Catherine puts great dedication and care into her work. She spends the time to do what’s best for her clients, and handled my writing with an incredible amount of thoughtfulness. There is no doubt Catherine is in your court. She gave me the direct feedback I needed, and set me on a smart path forward. Working with Catherine on my manuscript was one of the most enjoyable projects I’ve experienced over a decades-long career.
Alison McCauley, CEO and Founder of Unblocked Future and author of Unblocked: How Blockchains Will Change Your Business (and What to Do About It)
Catherine Knepper is a dream of an editor. She excels at both diagnosing the problem and figuring out a way forward. This combination is extremely rare: it takes special skill to understand not only what a writing project is, but what it might be. What’s especially wonderful about Catherine is that she is able to explain both what is wrong and what is right in a clear, supportive manner. I’d recommend her to any writer who wants a super-smart, talented, warm and professional editor who is both thorough and creative. She is the real deal, and seeing her work left me with just one word—wow.
Aviya Kushner, award-winning author of The Grammar of God
It was a magical experience working with Catherine Knepper. It began with a finely-tuned book proposal and finished with a 334-page product, Heal Your Heart: The Positive Emotions Prescription to Prevent and Reverse Heart Disease, in an insanely short period (4 months!). Catherine interviewed many of my patients, all of whom loved speaking with her and sharing their stories, and converted dull medical material into an interesting “page turner.” Perhaps my editor summed it up best by stating that this was the most complete manuscript she had ever received.
Dr. Michael Miller, director of the Center for Preventive Cardiology at the University of Maryland Medical Center
It seemed like I met a soul mate when Catherine and I talked for the first time about co-writing Against the Wind. I found a real treasure of talent and understanding in Catherine. Thank you, Catherine, as you have touched my soul and so many readers who have read our book!
Kirk VanHee, broker associate, backcountry ski enthusiast, and philanthropist
Catherine Knepper has been a critical member of our team as we researched, wrote, published, and promoted The Adversity Paradox. Whether it is editing, writing, or structuring ideas, she is highly proficient.
J. Barry Griswell, chairman and retired CEO of The Principal Financial Group, and Bob Jennings, president of Lean Management Group, Inc., authors of The Adversity Paradox, a Wall Street Journal bestseller
Catherine is gifted not just in crafting great prose and helping others craft great prose. She’s gifted in gently instructing and guiding you along the way so that your future work will be that much better.
Lia Huber, founder and CEO of Nourish Network and author of Nourished: A Memoir of Faith, Food, & Enduring Love
Many important eyes have looked at Fear and Faith in Paradise: Exploring Conflict and Religion in the Middle East, but few as discerning and imaginative as Catherine Knepper. She has played more than a few roles in the manuscript’s development, from copy editor and sounding board to fact checker and midwife. Her faith in the manuscript was untiring.
Phil Karber, author of Fear and Faith in Paradise and The Indochina Chronicles: Travels in Laos, Cambodia, and Vietnam, winner of the 2006 Lowell Thomas Travel Book of the Year Bronze Award
Catherine Knepper provided incisive and erudite criticism of my fiction manuscript. Her editing suggestions made good sense and improved the book immeasurably. I value her insights enough that I plan to ask her to edit its sequel.
Lisa King, author of Death in a Wine Dark Sea
Catherine is the ultimate teammate. She is always encouraging, and offers ideas and suggestions in such a positive way, she makes you want to keep writing. I especially appreciated her leadership in helping me create a structure that allowed my stories and ideas to flow, and to make sense.
Ambassador Mary E. Kramer (Ret.), author of More Than a Walk on the Beach: Confessions of an Unlikely Diplomat and An Unlikely Ambassador and Her Diplomatic Daughter: Stories & Recipes for the Life You Want
When I began writing my book I wanted to reach out to people who might also want to restore the natural quality of their land. But I had no idea how to go about getting published. Thanks to Catherine my writing project became a professional book proposal. The proposal drew the attention of every agent to whom it was submitted, and in the end was accepted by a top literary agent who offered representation less than three hours after receiving it.
Sibylla Brown, author of Timberhill: Chronicle of a Restoration
The idea to write a book came after 12+ years of running our own business. We had a genuine desire to share what we had learned with the next generation of entrepreneurs. We quickly learned that tackling this alone was not feasible, so after numerous interviews and false starts we were referred to Catherine Knepper. After the first interview we knew the search was over. Catherine has been exceptional to work with in every respect imaginable and has exceeded our expectations every step of the way. If you are looking for a ghostwriter look no further, Catherine is the best of the best.

Services

I work with traditionally and independently published authors, and offer a range of customized editorial and writing services that help make your writing project a creative and commercial success. I take particular care to preserve your unique vision, voice, tone, and style. Final approval for edits is always up to you.


Content Editing

Manuscript Coaching + Line Editing + Developmental Editing

My approach to content editing combines big-picture developmental work with detailed line-level attention. What you’ll receive:

  • Reader response
    I read your manuscript cover to cover first as an engaged reader, not an editor, noting what’s working and why. You can learn as much from your strengths as your weaknesses.
  • Line-by-line editing
    Detailed attention to flow, syntax, and clarity throughout the manuscript. Hands-on, sentence-level editing.
  • Editorial letter
    A careful assessment of the book’s overall strengths and weaknesses, with specific suggestions and a clear revision strategy.
  • Follow-up meeting
    An hour-long conversation to discuss feedback and clarify your revision plan.

After you revise based on my first-pass edits, you’ll send the manuscript back for a final round of editing that includes copyediting. The result is a polished manuscript ready for submission.

The fee for this service is $18 per page (1 page = 250 words).


Book Proposal Preparation

Content strategy & marketing for nonfiction authors seeking traditional publication

My Book Proposal Preparation service gives you a competitive proposal that’s ready to submit to literary agents, acquisitions editors, and publishing houses. I don’t just format what you provide—I collaborate with you to develop each component strategically, ensuring your proposal demonstrates both the book’s market potential and your ability to deliver it.

Components include:

  • Overview and hook
    A compelling case for why this book matters now, written to capture attention in the first paragraph
  • Author bio
    Positioning that establishes your credibility and unique authority on the subject
  • Marketing plan
    A comprehensive strategy covering media outreach, digital marketing, social media, speaking opportunities, partnerships, and audience-building tactics. This isn’t a generic checklist—it’s a tailored roadmap that demonstrates you understand your readers, where to find them, and how to build momentum before and after publication. This section alone often makes the difference between a pass and an offer.
  • Competitive analysis
    Clear differentiation from comparable titles that demonstrates your book’s distinct value
  • Annotated table of contents
    Detailed chapter summaries that show exactly what the book will cover and how it all flows together
  • Sample chapter
    Polished writing that shows agents and editors exactly what they’re buying and what you are capable of

We’ll work together through multiple drafts, refining the proposal until every element is as strong as it can be. The goal isn’t just to check boxes—it’s to build a document that makes agents want to read your full manuscript and editors want to acquire your book.

My rates start at $12,000. To date, every client’s advance has covered the cost of services.


Manuscript Collaboration & Ghostwriting

If you have a strong nonfiction book concept but need a collaborator to help bring it to the page, I work with authors to develop manuscripts that are both well-crafted and market-ready. My role is flexible: some clients provide detailed outlines and substantial content for each chapter, while others prefer I handle the research and writing. We’ll find the approach that works best for your project.

Timeline depends on scope, but a typical manuscript of 60,000–80,000 words takes approximately six months. If you need both a book proposal and a full manuscript, we can structure the work in phases or as a combined package.

My rates reflect the level of collaboration required, the timeline, and other factors such as profit-sharing arrangements. I don’t require a byline and am happy to sign an NDA. Contact me to discuss your project, and I’ll provide a proposal outlining deliverables, terms, and fees.


Consultation Hours

For shorter projects—articles, op-eds, individual chapters, query letters, or publishing consultations—I work at an hourly rate of $150.
