Student Reviews

Donald is an excellent teacher for senior professionals who don't have a lot of free time. He always offers intelligent conversation (which makes his classes interesting), and also provides practical knowledge of interest to professionals such as politics and economics. His concern about finding topics of interest for their students is that extra mile which makes a big difference. Also, Donald has provided me with invaluable help when applying for jobs in the United States and here in Costa Rica. He has reviewed my resumes and done practice interviews with me in English.   -- March 2025

Professor Donald has been key in regaining my ability to understand and speak English. His professional quality and methodology have been decisive in my process. For me, it has been gratifying during my trips to the United States -- and specially in New York City -- to have felt the change. My improvement in English skills when interacting with clients and friends was really noticeable. I found it much easier to speak confidently and to understand almost 95% of what people said to me. 

Honestly, having found Donald was a great achievement. Thank you professor Donald for being so helpful to each of us.  -- March 2025

Donald is the most amazing English teacher I have ever met! His lessons are not only educational but also engaging and fun – he teaches real, everyday English that is actually used by native speakers. He shares interesting expressions and phrases, making language learning feel more natural and practical.

I often worry about my skills and pronunciation, but Donald always supports, encourages, and helps boost my confidence. I can rely on him not only as an excellent teacher but also as a great advisor. He helped me prepare for a job interview in English, and thanks to him, it went perfectly!

Donald is not just a knowledgeable teacher – he is also an incredibly interesting person with a fantastic sense of humor. No lesson is ever boring! Every time, I feel progress, and I leave the class with a smile on my face.

I wholeheartedly recommend learning English with Donald. You won’t regret a single day!

Thank you, Donald! You are awesome!   -- March 2025

I have been working with Donald for almost four years. His classes are energetic and insightful, extending beyond typical conversational topics. He is an inspiring professional who not only improves your English but also shares valuable insights from his experience in Information Technology. With Donald, you’ll learn something new about the language, American culture, business, and social issues. -- August 2024

I am extremely grateful that Donald took me with him on a poetic journey with Walt Whitman. Studying literature has always been a passion for me, and now, thanks to Donald, I am once again delving into the world of poetry. Thanks to his knowledge and eloquence, our meetings are an extraordinary adventure and pleasure for me. Thank you Donald!  -- July 2024

Donald is an excellent tutor! The classes are fun and brisk because of his energy and enthusiasm. He explains the subtle nuances of the English language and American culture in detail. I realize how broad and deep his knowledge is by how he explains complex rules clearly and simply. In general, his approach is great for getting the learning material down quickly. This is how professionals work.

I feel more confident in spoken English now. The quality of writing has risen several levels, which is very important for my current role. And this is just a few months of regular classes.

I want to express my gratitude to Donald for his professionalism, especially his ability to explain any topic very well. I spent years trying to understand the Present Perfect, but he explained it to me in just three minutes. Since then I have had no problems understanding the Present Perfect. I also appreciate his support. I had a lot of insecurities about my accent, I felt like there was something wrong with me when I spoke English. All these restrictions disappear after each lesson. 

In addition, he helped me prepare for a professional interview. We worked on my resume and interview preparation and now I've landed a professional job in less than a month, which is a fantastic result. I am truly grateful to Donald for our work together, because it was a significant breakthrough in just a few months. My life has changed dramatically, and now I can speak without any complexes. Thank you very much for everything! -- February 2024

I'm so grateful to the day I came across Donald's profile on verbling.com in the fall of 2018. I've met not only a competent teacher who was interested in my progress, but also a beautiful human being and a guiding mentor. I loved recording our classes and listen to them afterwards, so meaningful and deep our conversations were. And I couldn't believe at first, but our classes had a great therapeutic effect on me as well. I felt much calmer and confident after each "session".

We're not having our classes anymore in 2023, but Donald will always remain my good friend. For present and future students of Donald I wanna say that you are incredibly lucky. Have a nice journey of learning English in this beautiful place called the Chicago English Corner! -- December 2023

"The teacher arrives when the student is ready" -- this perfectly describes my English learning journey and how I started, taking lessons with Donald for the last 3 months. He gave me guidance to practice and not be afraid to make mistakes in my job interview. 

I clearly remember my first lesson with him and how he helped me stay focused on my goals and not hesitate. Finally, I made it – I got a job in a global company.

Donald is so engaged with his students, always keeping up and celebrating how we meet our goals, as well as cheering us up when things don't go well. If you need to improve your English to get your dream job and willing to be coached by an expert, Donald is definitely your person. -- December 2023
