What Clients Think
"...with David's storytelling techniques, I could finally organize the chaos in my mind and use a clear structure to prepare presentations. David CAN HELP!"
"David is amazing and the data science English classes are one of the most interesting things I have done on data science. From interview preparation to speaking with confidence at conferences, David provides you all the story-telling frameworks that help you explain complex concepts and tell stories in an exciting way. A really good investment on my career."
I started to work on improving my story-telling and communication skills in English with David in August 2020. I was astonished by the quality and brightness of his approach and immediately recommended his program to my friends. I have decided to share my recommendations on Linkedin as well. If you strive to be better in communication, either public or private - David will help you!

Before, I was really afraid of using English to do presentations or have an English interview. I would be stressed, nervous, and speechless. I needed to memorize the transcript, otherwise, when audiences asked the question out of my preparation, I would totally draw a blank.
However, after taking David class, it totally changes my way of preparing a presentation or an interview. He taught me how to speak in a storytelling formula without memorization, how to present in a persuasive way, and also taught me how to hold an engaging presentation.
Now, when I face an English presentation or interview, I still feel nervous but I have more confidence than before. Besides, when people ask me questions, I can answer fluently and persuasively without memorized the answer beforehand.
Last but not least, David is a really patient and hard-working teacher, so don’t be afraid that your poor English will cause the teacher to feel annoyed! I think most Asians will have this concern. During these 10 classes, I never saw David feel impatient or lost his passion for teaching.
Do you have trouble with English presentations or interviews just like me? Don’t hesitate to take the class!!!
I took his classes in order to prepare technical case interviews in BCG Gamma. The remarkable points of his classes are threefold:
(1) He consistently taught me the importance of storytelling, which made it easy for me to structure my answer logically.
(2) He provided highly customized lessons with me, meeting my needs to get ready for technical case interviews.
(3) The lesson fee was very reasonable, and the ROI was greater than other competitors.
The result: thanks to his lessons, I was able to get an offer from BCG Gamma! I recommend his interview-prep course to every data scientist who is in the face of business/technical case interviews but not certain about how to address them. David is for sure to give you appropriate guidance to pass them and get your dream job!
David is a great teacher! I am a native French speaker and the two main areas I would like to improve prior to the course were practicing my English and be able to give better presentations. In both these areas, David was of great help.
He helped me with more appropriate formulations and storytelling techniques that I have already put in place. It gives a new turn to my presentations which are now more engaging. He also coached me for an interview and it was very helpful. If you are willing to improve, do not hesitate!
David knows how to captivate attention, teach complex concepts and encourage participation. Through his advice, I found an international internship and I know now how to explain data science concepts to different kinds of audiences. I am also more confident in English now and I really improve my expression and my comprehension. I really enjoyed his course and I definitely recommend them.
The lessons changed my way of presenting.
Before the lessons, every time I have to do a presentation I would be anxious and nervous because there will be too many thoughts come out in my brain and make it blow up. As a data scientist, sometimes I need to communicate with clients, and presentations really bother me. But with David's storytelling techniques, I could finally organize the chaos in my mind, and use a clear structure to prepare the presentation. David CAN HELP.
David is also a patient and conscientious teacher. The patient part is that every time I think for a long time in the class, David would wait for me until I finally come up with some answers. And the conscientious part is that David would answer my questions very precisely. I asked him how should I think when I don't know how to find an appropriate example when explaining a data science concept or an algorithm. I supposed the question is not easy to answer at first, but David's solution really surprised me. With David's solution, I found that it becomes easier for me to come up with ideas. (As for the solution, you could ask David yourself if you are curious 😉 )
Maybe you will have heard of some of the concepts in the lessons, but only through the practice with David, could you turn the concept into real skills. The structure of storytelling is simple, useful, and practical. I really like the way David engaged with us.
