"Due to family moving in recent years, my son has switched 3 piano teachers in his 5 years of piano study. I approached Dr. Chang a year ago, because my son really enjoys playing piano, and I felt he has reached to a point where he needs more structured and professional training for him to advance more and faster. Over the past year, our son has made remarkable progress in his piano study. I have limited knowledge in music and piano, but am fortunate to be able to enjoy music, and tell the difference in the music my son has played, and level of excellence he has reached. My son has won the 3rd place in 2017 Dallas piano competition in his age group. Although competitions as such may be opinionated, but without instructions from Dr. Chang, I don't think my son could have accomplished it. I am sure my son will learn more from Dr. Chang in the years to come.”
