Latin America doesn’t have an English problem. It has a spoken-English problem.
Millions understand English. Then the meeting starts, and they freeze.
Across Latin America, professionals have studied English for years. They hold certificates. They understand almost everything they read and hear. Then a client calls, an interview begins, a US colleague asks a question, and the words don’t come. The problem was never knowledge. It’s processing speed under pressure: the gap between knowing a language and producing it in real time. And the cost is personal: the colleague who speaks up in English doesn’t know more, he understands the same. His answer just comes out under pressure, and he gets the U.S. client, the promotion, the international role. That gap is trainable.
Rapid Fire English trains that gap directly. It treats fluency the way athletes treat a skill, as a reflex built through repetition, not a fact to be memorized. The result is professionals who can finally respond in the moment that matters, in their own words, without translating in their heads first.
Founder Monica Barrero lived the problem before she solved it. She arrived in the United States with a B2 English certificate, and couldn’t answer a single question at immigration. Not for lack of English, but for lack of training in the one skill no course had built: responding under pressure. Fifteen years and a career across US multinationals later, she built the system she wished she’d had, and made it her mission that fluency become an economic equalizer, not a privilege.
The spoken-English gap, in data.
Monica Barrero
Monica Barrero is a Colombian founder and U.S. citizen based in Bogotá. Before Rapid Fire English, she spent roughly 15 years in sales, marketing, and business development across industrial and energy multinationals, Crane ChemPharma & Energy, Aerzen USA, and Daniel Measurement & Control, much of it leading Latin American markets: from LATAM sales and applications at Crane, to Regional Sales Manager at Aerzen USA, to Director of Marketing at Daniel Measurement & Control.
She knows the pain firsthand: she landed in the US with a B2 certificate and froze at immigration, because understanding a language is not the same as producing it under pressure. That experience became a conviction, that the barrier holding back talented Latin American professionals isn’t intelligence or effort, but training in real-time response. She founded Rapid Fire English with co-founders Sal Marrone (product) and Enyor Piña (technical) to train that response directly.
