"The classes with teacher Jonathan are never boring. He can catch your attention even at 09:00 p.m. or 10:00 p.m. after a 24-hour shift. He masters the techniques of teaching ad preparing for your need in English such as: Travel, speeches, internships. It was completely worthwhile for me. I am not that kind of person who feels comfortable speaking in public, imagine in English. But I improved a lot after the classes. Thank you for your commitment and support teacher Jonathan."

"When you are at war, the soldier that is shoulder to shoulder with you makes all the difference. Jonathan and I are in the same trench in this fight. Please, don't picture a bloody war, but a struggle of knowledge and ignorance, of employment and unemployment, of success and failure! I believe in Jonathan as a friend and as a professional in my daily challenges. Hemingway was right. Thanks, mate!"

"I'm here to give a special thank you to my English teacher Jonathan! I have just finished my dissertation, one step closer to my master degree, and I actually wrote a part of it in English, all by myself! His classes really helped, so thank you very much! See you soon, I hope. Stay safe."

"Jonathan is gifted. He can teach any human being in this galaxy! The way he can use different techniques to make sure that you understood something is literally from another world. He can keep things as simple as possible and also walk you through the worst-case scenarios to help you to get more confident about what is already in your mind that you need to spit it out.
He’s classes are just as good as the person itself. He is amazing!"

"Gostaria de deixar meu depoimento : Jonathan é um professor que traz a língua estrangeira
para a realidade do dia a dia. Dessa forma, o aprendizado se torna fácil e prazeroso!"

"Jonathan is one of the best english teachers of Porto Alegre, the method of his classes helped
me a lot to improve my speaking skills!!!"
