Testimony of a former student: "Dear Dr. Chui, Thank you for the support and kindness you've shown me. I met you at one of the most challenging times in my life. Due to administration in my district, my academic future was in disarray. However, your help aided me in finding my confidence in math again. You are truly remarkable at what you do. When you teach, you go into great depth in a array of topics, advancing my learning experience. You teach with passion, which inspires me to want to learn even more. I truly have appreciated your kind thoughts and words. At this time, I don't have much support in my life. Your kind messages touched me, reminding me that there are still people that think of me. Thank you for everything! R. S."

Testimony from a parent: "Hi Dr. Chui. I just wanted to let you know that Diego got an A on his final in Statistics. Thanks so much for your help this semester." D.C.
