Orchestra Camp during the summer time is a good way to for your student to continue to play and grow as musicians during the Summer Break. It's a good way for students to meet other musicians, work with other directors, and expand their musical world. I began attending camps following my 7th grade year and always enjoyed myself.

Below are camps that I attended or have been recommended to me by current and former students.
