At the link below is a pdf of a rationale for private lessons and its benefits, and also the contact info of lesson teachers. Please consider taking lessons in the summer. The instructors have proven to be flexible and accommodating of student schedules, vacations, etc., and will work to help your child grow on their instrument. In many cases, students will get better in the summer far faster than during the school year. We all understand the benefits of 1:1 learning and there is no better scenario than one teacher for 1-2 students.
Thanks so much and I hope you will consider this!
