About Main Line Memoir
Hi. It’s great to meet you.
Why We’re Different
We create all kinds of books for all kinds of people. Some have been bestsellers and won awards. Others have had print runs in the single digits with a copy for Mom, Uncle Lou, and the grandkids. We believe that when done with care, intention, and honesty, the impact of any project can be extraordinary no matter the scale.
Why Work With Us?
We specialize in memoirs, personal histories, family legacy books, and meaningful life stories.
We know how to listen closely, ask the right questions, and shape a lifetime of memories into a clear, compelling narrative.
We write with discretion, sensitivity, and respect for the privacy of your family, your history, and your voice.
We bring professional publishing experience to every project, including writing, editing, design, photo selection, printing, and production.
We assemble the right team for your book, including writers, editors, designers, and publishing professionals. When a project calls for additional support, we can also bring in genealogists, archivists, oral historians, photographers, videographers, documentary producers, illustrators, mapmakers, photo restoration specialists, private printers, and bookbinders.
If traditional publishing is the right path, we can help refine your concept, prepare a book proposal, and identify and query appropriate literary agents.
We guide you through each step so the process feels manageable, thoughtful, and professionally handled.
Meet Main Line Memoir
Diana Holquist
FounderDiana spent her formative years as an advertising copywriter in New York City writing award-winning ads for Pepsi, Doritos, Sony, BMW, and other international brands.
After eleven years, she left the big city to raise a family. She also wrote and published five books with Hachette Book Group, a children’s book with Penguin Random House, and a parenting memoir with Five Directions Press.
But she missed the collaboration of her advertising days—working closely and intensely with smart people to create something remarkable.
Ghostwriting memoirs was the best of both worlds. Smart people and smart books! She loves her job and brings that passion and professionalism to every project.
Her mission is to help all people get their stories out into the world. She’s a graduate of Columbia University with a degree in philosophy and lives on the Philadelphia Main Line with one cat, two kids, one husband, and way too many books.

Question and answer
When are you frugal?
With praise. A book is forever. If it's not good enough for the page, it's our job to tell you.
When are you extravagant?
With praise. It's hard to get a story just right: honest, clear, and worth reading over and over. That's an achievement to celebrate.
What do you admire most in your authors?
Honesty. It is the foundation of any meaningful memoir, and often the hardest thing to achieve.
What will you always do?
More than expected. We ask our authors to go beyond the obvious, so it is only fair that we do the same.
