I'm Daniel, a business English specialist with over 15 years of professional experience in market research and strategic planning, complemented by an MBA. I enjoy working with you to make your English more professional. I also earned a Master’s degree in Latin American studies, reflecting my deep regional expertise. Having traveled extensively across Latin America—including Brazil, Mexico, Argentina, and several other countries—I am fluent in both Spanish and Portuguese. My passion for languages has now led me to focus on teaching, where I help professionals refine their business English for conversation, meetings, emails, and presentations.
Me as a Teacher
I want to help you to speak English more confidently. You may need to practice speaking English for conversations or presentations. You may need to improve writing for reports or for email communication. You may need to understand spoken English better. I know you can improve all these things with practice. You can improve your English skills to make a great impression on customers, colleagues, managers, and friends that speak English.
My lessons & teaching style
I want to help you to develop English skills that you can apply professionally. Let's work together to design a plan. We can focus on listening and speaking. We can focus on email communications or on presentations. We can focus on conversations with customers and colleagues. We can discuss material from Tedtalks, YouTube videos, business cases, or current events. You do not need to say everything perfectly but you do need to communicate effectively and with confidence. Let's work together to get you there.

Learning with Daniel was relaxed and stress-free, yet very effective. He helped me prepare for my business presentation through repeated practice and careful listening to my needs, and it went smoothly in the end. I really appreciate the support.
