John has been my teacher for four years now, and I could not be more satisfied. His approach is simple and friendly, which makes learning easy. My listening skills, vocabulary and accent have improved a lot and I have increased my confidence in speaking.

My name is Helena Guerra and I'm a medical student. I've been studying with John for about 2 and a half years. Recently I spent a month in NYC doing a dermatology elective at Cornell University.  John helped me a lot to prepare myself to go there. And the result came when a patient who used to be a high school English teacher in N.Y. told me I had a very good English. I was also able to attend patients by myself and discuss diseases with the teachers; this showed me how prepared I was. Class with John is always fun. He manages to make every class pleasure. What I like the most in our classes is learning new idioms. He has lots of materials to work with and you never get bored.

I like to be "English coached" by John because he has the four elements necessary to learn a new language: nice teaching technique, a global culture level, good humor and professionalism. I prefer to use my free time living great moments... John's class is more than learning... it is to share experiences.

I have been John´s student for 8 years. Our classes are focused on conversation and discussion about the current topics in Brazil and all around the world. With the conversation classes I could improve my pronunciation and grammar. But in my opinion the most important [thing I learned in] our 8 years of classes together was losing my inhibition for conversation with natives Americans. This was really most important for me, thanks to the John´s professionalism and dedication.

John is a wonderful teacher and his classes have a great dynamic. He observes the students' difficulties and adapts the classes to address the issues. Every Friday, he sends the next week's plans. He is concerned about bringing different materials and is open to suggestions. John is always in a good mood and the way he leads his life is such an inspiration. My English classes are really a fun time that make me feel better during the day as I have a very stressful job. This is my first experience studying online. Online classes fit well into my hectic schedule.

Our classes are mostly based on conversation, which helps me to get much out of every situation in English I have been faced with, from meetings and conference calls with foreign clients to trips and courses abroad.

As John is a cultured and nice guy,  we talk a lot about the most diverse matters, which makes learning really natural. John has also really good taste in music, and knows how to use it to teach.

I am also obtaining great results at work thanks to better quality of my e-mails, reports and memos in English

I'm a pediatrician and I did other English class for 6 years, but I never talked in English because I didn't feel safe. I have started my English class with John 2 months ago and I have [been] talking with him, I think that I have [been] getting better every day. Today it's easier to watch movies and hear music in English or sometimes with subtitle in English. I'm recommending John's English class because I trust him and his classes is customize for the trouble of each student, it's very nice!

At first, English class by video didn't sound attractive to me because it's tough to hold my attention, but now, I know I couldn't choose a better way and a better person! As an endocrine fellow, I have a complicated and busy schedule. [T]his way, the English classes with John by Skype are perfect! I still can have classes from different places! I've been studying with him for 7 months and I couldn't be more satisfied! I spend one month at the Hospital for Sick Children in Toronto recently and our English classes were very helpful!

John has been my English teacher for the last 7 years. With him I improved my accent, pronunciation, writing skills and other things. I am still studying with him to keep a good proficiency with the language. What I [like about] John as a teacher is his commitment, and the opportunity to talk about different subjects in another language. This second is very interesting when we compare to the formal courses. In regular courses the text books often simulate simple subjects and common life situations. However, with him I can discuss interesting ideas about different areas (sports, economics, job situations, world affair, etc) with pleasure.

I've been having classes on Skype with John for two years. He is a very good teacher, always concerned about finding subjects that could interest me and he is incredibly at ease in every field of knowledge, including my professional area that is pancreatic and biliary surgery. Music, literature, TED subjects, etc, in a very friendly way to communicate, showing my mistakes very politely. Really very pleasant.
