Thirty years of experience in journalism and the publishing world is easily said. Yet, I feel so open to learning that I like to imagine what comes for the next 30 years. As a writer, editor and proofreader, my passion for the written word keep me discovering new realms. Bilingual (Spanish-English), I’m a language lover who’s going through French and Italian as well (I don’t know what comes next, Russian?). My goal in life is to have things done as best as I can, and I take pride in it. Contact me.
