As a former professional musician, I have had a lot of experience with music instructors, and know what qualities make a great teacher. Alex has been my son's drum teacher for seven years now, and has done an outstanding job. He is patient, clear in his instruction, and challenges my son to reach his full potential. Although my son is only 11, he's begun playing with an intermediate-level improvisation class in town that is made up of teens and adults, and has been excelling. I know there is no way he would have gotten this far without Alex's guidance and encouragement. When Alex moved to California a couple of years ago, I was concerned that his lessons with my son would not be as strong without his actual presence. However, we have maintained weekly lessons via skype, and the lessons have been as strong as ever. We also send him short clips during the week of my son's progress, and we get almost instant feedback and guidance. Alex has also taken the time to get to know my son, including his other interests and sensibilities. I can't imagine a better teacher for my son. We feel very blessed. I give Alex my strongest endorsement.
