What our students say
★★★★★
“Valdo is a phenomenal teacher: attentive and creative. After three weeks of classes, I already see a dramatic improvement in my confidence speaking and understanding Spanish.”David MargoliusDirector of Public Health for the City of Cleveland2-3 Spanish lessons a week for over a year
“Excellent teacher. I have worked with him over the past year and have truly become more fluent and conversational.”Karim KhanPhysician at Boston Health Care for the Homeless Program1-2 Spanish lessons a week for over 3 years
“Thank you, Osvaldo, for the incredible work you did on behalf of Solx. Your translation skills, professionalism, and ability to communicate across languages and cultures were invaluable to our project.”Ian HahnDirector of Supply Chain and Logistics at SOLXSpanish <> Mandarin <> English translation services for over a year
“Two and a half years ago, I did not know how to speak Spanish. As a Puerto Rican in the diaspora, I had always wanted to learn my heritage language. Osvaldo was my first and only Spanish teacher. His classroom style is very kind and, at the same time, very rigorous.”Dr. Charles AthanasopoulosAfrican American Studies Professor at Ohio State UniversityHeritage speaker from New York
“I am on a mission to learn Spanish, and Valdo is the best. Every week he brings new material or reviews what we need so it really sticks. He offers great variety, shares resources to practice outside class, and is a fantastic teacher.”Yvonne VoGraphic Designer from California2-3 Spanish lessons a week for over 3 years
“Relearning Spanish with Osvaldo has been an incredibly rewarding experience. He is a patient, encouraging, and highly knowledgeable tutor who tailors lessons to my individual interests, pace and goals (from reading cultural reviews, poetry, and history to listening to music and reading song lyrics). His engaging teaching style is fresh and contemporary and makes complex grammar concepts easy to understand. He is focused and always brings it back to the lesson while creating a comfortable environment that has truly boosted my confidence in speaking. I highly recommend Osvaldo to anyone looking to improve their Spanish skills.”Luis De JesusGallery Owner in LAHeritage speaker from California
“I have been studying Spanish with Valdo for a few years now to be able to better connect with my in-laws who are native Spanish speakers. He is an excellent and reliable instructor, who always pushes me via diverse lessons and methods of teaching, including conversations, grammatical practice, translation exercises and cultural discussions. While I still have a lot to learn, I know my Spanish has improved greatly under Valdo’s guidance. Being able to have dedicated, one-on-one instruction has made all the difference for me. Looking forward to continuing our work together!”Christopher PettisVP at JPMorgan Chase & Co.Married to a Puerto Rican
“Osvaldo is an exceptional language professional who excels as both a teacher and an interpreter. His passion for language extends far beyond vocabulary and grammar, he has a deep understanding of the cultural context, nuances, and subtle meanings that make communication truly effective. As a teacher, he is patient, engaging, and highly knowledgeable, helping students develop real confidence and fluency. As an interpreter, he has a remarkable ability to accurately convey not just words, but the intent, tone, and meaning behind them. His professionalism, expertise, and genuine dedication to language make him a valuable resource for anyone looking to learn a language or bridge communication across languages. I highly recommend Osvaldo to anyone seeking a skilled teacher, interpreter, and language expert.”Chance MillonConsultant and investor in the renewable energy sector
