Olga Martin – Translator

EN→ES fiction & nonfiction book translator | 30+ years. Human translation & review of existing drafts. Spanish that reads like an original.

Overview

Hello, and thank you for stopping by.

If you're an indie author preparing to publish in Spanish, I can help your book read naturally, confidently, and at a level that stands alongside professionally published titles. If you already have a translation, I can also help you assess or improve it.

I bring over 30 years of experience translating fiction and nonfiction from English into Spanish, including 27 years of collaboration with Planeta, Spain's leading publishing group. My work includes serving as the official Spanish translator for Peanuts and Garfield, and contributing regularly to the Guinness Book of Records.

I've translated full-length books across a wide range of genres, always with close attention to consistency, tone, and rhythm. The goal is not just accuracy, but a Spanish version that preserves the author's voice and feels natural, fluid, and fully alive to the reader.

I can tailor the Spanish to your intended readership, whether in Spain, Latin America, or the US Hispanic market.

Depending on your needs, I offer:

- Full human translation: From English into Spanish, with careful attention to voice, style, and readability.

- Translation assessment: An independent professional evaluation of an existing translation, including AI-generated or machine-translated drafts, to identify its strengths, weaknesses, and readiness for publication.

- Editorial refinement: In-depth revision of existing translations to improve accuracy, fluency, tone, and consistency, bringing them up to professional publishing standards.

I work in a direct and professional way, and I am honest about fit. If I feel your project is a good match, I will tell you clearly. If not, I will say that too.

You're welcome to read the reviews shared by other authors to get a sense of what it's like to work together.

I'd be happy to hear about your book and discuss the next steps.

I hired Olga for a quick review pass on our Spanish ecommerce storefront copy, and it was a great experience — as it has been every time I've worked with her.. She turned it around quickly and the quality was exactly what I'd come to expect based on her previous work on our project. Easy to work ...
