Writing Development / Ghostwriting

We match writers to each of your Spanish-language projects. At Base Tres we also help you develop your own stories through specialized ghostwriters who will make sure your message gets across.

English-Spanish Translation

Our extensive experience in the American Spanish-language editorial market enables us to work on versions that appeal to all US Spanish-language readers.

Our native Spanish-speaking translators come from all over Latin America and Spain and translate into neutral Spanish (if desired) or into various Spanish dialects without compromising the linguistic richness of original texts.


Copyediting is done according to strict quality-assurance standards, with manuscripts checked against originals at every step along the way. A style sheet is delivered with every copyedited manuscript.

Why Publish in Spanish?

Spanish is the second most widely spoken language in the world with approximately 414 million native speakers. Its influence has spread and the number of non-native speakers has expanded steadily over the last thirty years.

The Spanish-speaking population in the United States has expanded rapidly. By some measures, America is now the second largest Spanish-speaking country in the world. Spanish is usually the first foreign language learned by English speakers in the United States, and its future prospects look bright, in particular since California reinstated bilingual education in 2016.
