Quiero destacar la excelente experiencia que estoy teniendo en mis clases de inglés. El profesor explica todo de manera muy clara y tiene un estilo de enseñanza que realmente se adapta a lo que yo necesito. También valoro muchísimo su carisma y la buena energía que transmite en cada clase, porque eso hace que las clases sean amenas y motivadoras.
Algo que aprecio especialmente es lo rápido que capta qué temas ya entendí, cuáles necesito reforzar y cómo acompañarme para seguir avanzando. Me siento muy apoyada durante todo el proceso, y noto que las clases fluyen de forma natural.
La verdad, lo recomiendo sin dudar.

I want to highlight the great experience I’m having in my English classes. The teacher explains everything very clearly and has a teaching style that really adapts to what I need. I also really appreciate his charisma and the positive energy he brings to each class, because it makes the lessons pleasant and motivating.
Something I value a lot is how quickly he notices which topics I’ve already understood, which ones I still need to work on, and how to guide me so I can continue improving. I feel very supported throughout the whole process, and the classes flow naturally.
I truly recommend him.

Boris es un gran docente. Me ayudó mucho a empezar a escuchar y hablar el idioma. Sus clases son conversaciones agradables sobre la vida, la música y el arte, por lo que las hace muy entretenidas y amenas. Super recomendable.

100% recommended! I'm currently taking online classes based on conversation, with pronunciation and grammar correction and teaching of native expressions. He's a patient, attentive and flexible teacher. His classes are entertaining and provide an immersive language experience.

Totalmente recomendable! Actualmente estoy tomando clases online, las que se basan en aprender mediante conversación. Durante la clase el profe te va indicando cómo se pronuncia correctamente, corrige errores gramaticales y enseña o sugiere expresiones nativas como alternativa para comunicar una idea. Además, complementa las clases con el envío de ejercicios para realizar, aporta consejos para mejorar el aprendizaje y está predispuesto para resolver dudas entre clases. Es un profesor paciente, atento y flexible, adaptándose y manteniendo una conversación fluida de acuerdo a lo que surge en el momento y a los intereses y el nivel de inglés que uno tiene. Las clases son amenas, relajadas, entretenidas y una experiencia inmersiva en el idioma. Es un 10 de 10.  

Taking classes with Boris has been one of the best decisions I’ve made to improve my English. From day one, his teaching style felt clear, enjoyable, and motivating. He has a special gift for tailoring lessons to exactly what you need, and that made all the difference for me.

More than just a teacher, I felt like I had someone truly supporting me throughout the process. I recommend him with complete confidence!

Thank you for that

I’ve been studying English with Boris for over 4 months now and I could not be more pleased with my progress and him as a teacher. Being native in both English & Spanish gives him an edge I haven’t experience with other teachers on my English learning journey, it makes it a very smooth transition if I ever get stuck on anything. He’s patient and extremely knowledgeable and passionate about languages and seemingly every other topic! His passion and cultured nature makes lessons all the more interesting and enriching— they just fly by! I’m very excited for my learning journey ahead with Boris as my teacher. I wholeheartedly recommend him, no matter your level.

I took classes with Boris in person for like a year, which is a key reason of how I came to understand, write and speak English.
Beyond his interest in languages in general, his knowledge of grammar, and his easy going personality, one of his biggest assets is being a native speaker of both English and Spanish (my native tongue). I found this invaluable due to his understanding of both accents.
Of course I recommend Boris as a teacher because of the above and also because of his interest in getting to know what you want to learn specifically and how to get you there, since he knows that each person learns and understand as different as they also talk and communicate in the first place.

Un genio Boris!! El mejor profesor de español e inglés que he tenido!

I took lessons with Boris to improve my English skills and I just can say that my experience with him was excellent.
We had long talks in a chill atmosphere about several topics of my interest, in which he managed to pointed corrections to me, explained grammar, vocabulary and teach useful tips to enhance my speaking.
One of Boris main advantages is that he has English and Spanish as mother tongues, while in addition he speaks French and Japanese.
Not expensive at all. I would definitely recommend Boris to beginner as well to advanced students.

I started learning English with Boris 3 months ago and I think the most important thing I can say is that I am now writing this message without a translator.
Boris is an English teacher with a keen interest in many disciplines: music, history, culture, biology. This virtue leads his classes to revolve around very entertaining conversations, a very interesting method for learning another language, accompanied by extra material for weekly practice.
It's the closest thing to having a coffee with a great friend you haven't seen in a long time who has many interesting things to share.

I’ve been learning Spanish with Boris for several months and am really happy with the progress I’ve made. He is a very patient, calm person who has lots of energy and a passion for teaching. He explained grammar in detail which helped my understanding and ability to use the correct form when speaking. All our lessons are interesting and I was definitely able to speak and understand Spanish in a short time.
