Want your message understood accurately by over 500 million Spanish speakers?
Whether you’re serving Hispanic clients in the United States, expanding into Latin America, or publishing content for international audiences, clear and culturally accurate Spanish communication can make the difference between being understood and being ignored.
I help law firms, healthcare organizations, businesses, and authors communicate naturally with Spanish-speaking audiences across the U.S., Latin America, and Europe—without the inaccuracies, cultural missteps, or awkward phrasing that often come with generic translation services.
With 26+ years of experience and a consistent 100% Job Success Score, I provide publication-grade translations for legal, medical, marketing, technical, and full-length book projects. Clients work with me when they need a translator who understands both the language and the subject matter behind it.
My clients are often trying to do more than translate words. They may be reaching Hispanic clients, localizing a website, publishing a book, supporting patients, training employees, or expanding into Spanish-speaking markets. My goal is to ensure the Spanish version feels natural, professional, and trustworthy to the people reading it.
What I specialize in:
Legal Translation
Contracts, agreements, HR documentation, NDAs, benefit plans, immigration materials, confidentiality policies, dispute letters, and other legal or insurance-related content. I pay careful attention to terminology, jurisdiction, and tone so your documents are reliable and ready for use.
Medical & Healthcare Translation
Clinical reports, patient records, discharge summaries, consent forms, health questionnaires, insurance communications, and provider-facing materials. My background in psychology and experience in health and insurance operations help ensure clarity, precision, and sensitivity.
Website, App & SEO Localization
Corporate websites, software platforms, landing pages, marketing funnels, e-commerce content, app interfaces, and multilingual digital experiences. I adapt tone, terminology, and cultural references for U.S. Hispanic, Latin American, and European Spanish audiences. For websites and apps, I can work directly from HTML, JSON, CMS exports, and other source files while preserving structure, metadata, SEO elements, and user experience.
Technical, Business & Professional Documentation
Safety manuals, SOPs, training materials, product documentation, internal communications, presentations, UX/UI content, and operational documentation. I focus on clarity, consistency, and terminology accuracy so teams can rely on the final document without confusion. I can work directly from source files such as DOCX, PPTX, HTML, XML, and CMS exports, helping preserve terminology, formatting, and workflow efficiency throughout the project.
Book Translation & Long-Form Projects
Novels, memoirs, educational content, and non-fiction manuscripts. I work closely with authors and publishers to preserve voice, rhythm, humor, emotion, and pacing so the Spanish version feels like an original work. For authors working in Adobe InDesign, providing an IDML export allows me to preserve formatting, styles, and layout throughout the translation process.
How I Work
• I ask clear questions instead of guessing.
• I maintain consistent terminology using glossaries and CAT tools when appropriate.
• I preserve or rebuild formatting so files are ready to use.
• I communicate responsibly and meet deadlines.
• I handle all content—especially legal and medical materials—with confidentiality.
I work with Word, Google Docs, PDFs/scans, Adobe, WordPress, PowerPoint, Excel, JSON, XLIFF, SRT subtitles, and other structured formats. When needed, I use OCR and DTP tools to replicate complex layouts and preserve document integrity.
Who I’m a Good Fit For
• Law firms and legal departments
• Healthcare providers, clinics, and insurance companies
• SaaS and technology companies with English documentation
• International businesses expanding into Spanish-speaking markets
• Authors and publishers seeking a culturally faithful Spanish edition
• Organizations that need precise, polished communication rather than quick machine-generated output
When projects require CAT tools or client-specific workflows, I work with Trados, MemoQ, Wordfast, Smartcat, and other translation platforms.
Whether you’re translating a contract, a medical document, a website, or an entire book, my goal is the same: to make your Spanish content read naturally, accurately, and professionally from the very first draft.
Send a sample or project brief, and I’ll provide a clear quote, timeline, and recommendations for terminology, formatting, and workflow.

I am a native Spanish linguist with over 15 years of experience providing translation, localization and proofreading services from English and French to Spanish.

Through my ample career I have successfully completed all sorts of projects for companies like Siemens, Microsoft, Ansell, Merklin, or Estée Lauder, to name a few; I have also developed a solid, error-proof translation process that includes an in-depth previous reading and a thorough proofreading as a standard. Together with frequent communication, this process allows me to deliver a top-quality product, every time.
