Hello, I’m Jeffrey Yamaguchi, a published author and book marketing expert.

A Lifetime in Books

I work with authors and publishers to successfully launch books and build publishing programs.

I’ve been very fortunate to have spent most of my career to-date in the publishing world. As an author, I’ve self-published books, been published by a Big 5 publisher, and had stories and poems published in numerous literary journals. And as a marketer, I’ve worked and run departments at publishers both big and small, leading campaigns for some of the most successful, bestselling authors of all time, as well as writers who are just launching their careers. My inspiration is fed by what happens in the publishing space, and I love being a part of the community that drives what’s going to happen next.

Client Testimonials

  • Ellie Yang Camp, Author of Louder Than the Lies

    “As a first time author, Jeffrey was vital to making my first book launch a success. His vast expertise of the publishing industry combined with his encouraging demeanor gave me reassurance and direction during a process that felt daunting and dizzying. He graciously and thoroughly answered all my questions, coached me on how to set up launch events, offered much insight on the behind-the-scenes of bookselling, gave timely reminders about what tasks I needed to accomplish, kept organized records, and kept communication smooth with my publisher, booksellers, and media inquiries. Jeffrey is simply a pleasure to work with… I am grateful to have had him in my corner."

  • Pallavi Sharma Dixit, Author of Edison

    "It was wonderful working with Jeff on the campaign for my debut novel, Edison — He provided invaluable ideas, guidance, connections, and strategies, and I am extremely grateful for his diligent efforts to get media, reviews, and events for the campaign, including the incredible citywide ‘Edison Reads Edison’ program launch. Not only is he an expert in his field, but he is also a joy to work with. I most certainly recommend working with Jeff, especially for those writers that are publishing their first books.”

  • Cadwell Turnbull, Award-Winning Author of The Lesson, No Gods, No Monsters, and We Are the Crisis
