Messages from students

“선생님,

I just wanted to reach out after a year of college and tell you thank you for all the time and effort you put into our weekly tutoring lessons. I truly believe that your constant words of encouragement and engineering insight lead me to find interest in electrical engineering. I’m still unsure what I want to specialise in, but I have already learned so much in one year at UIUC.

I just opened up the box of all the electronic kits you brought me and I got reminded that I am so grateful to have had such a nice teacher who truly cared about helping me become a better student beyond teaching me a textbook and helping me become a better person.

You really had such a great impact on my life, and I just wanted to thank you even though it may be overdue. I hope you are doing well and staying safe. I will really try and stay in contact more often.”
