The owner and instructor, Randy Ching, has been working with my middle schooler for several years. Over this time, my son has excelled in math and reading comprehension. More importantly, he has developed better focus and the proper mindset to tackle academic challenges. Randy is a great instructor who obviously cares about his students and parents. He is very personable and always accessible to us when we have concerns. I highly recommend Kumon Aina Haina.
