I am proud that my child graduated from her classes with the best teachers in the state of Arizona! Being a fashion designer, my child has made progress in her artistic abilities through the visual and performing art electives here at Kellis! She did incredible extracurriculars in fashion and drawing, but as well as her teachers as a great guide to her career pathway. THANK YOU, TEACHERS!!
