Guest Artists
Dr. Ariana Kim - violin
"Having had the chance to immerse myself in the Castillero Middle School Orchestra classroom for several days every year over the last decade has made a lasting impact in my life. To see the power of performing arts education - especially when led and delivered by such a dedicated citizen-artist as Scott Krijnen - renews my faith in humanity. The lessons Mr. Krijnen teaches go on to deliver high-level concerts, but even more importantly, enter students' lives in the form of passion, mindfulness, cooperation, diligence, and respect. CMS Orchestra students come to class each day from varied backgrounds and life experiences, but show up in a wholehearted way to embrace the craft of making music together, taking pride in their work as one. I look forward to my visit there with great enthusiasm every year."

"Castillero Middle School is a remarkable place where young musicians are encouraged to explore their full potential within a vibrant and supportive community. The orchestra program, led by the exceptional Scott Krijnen, stands out as a high-quality program that fosters not only musical excellence but also kindness, camaraderie, and personal growth. The positive, uplifting environment Scott has built inspires students to grow both artistically and personally, creating a true community of support. Visiting Castillero each year and working with such incredible talent is one of the happiest, most fulfilling experiences I look forward to. I can’t wait to return in October 2025!"

We were beyond impressed and are grateful to have been part of such a vibrant and well-prepared community of young musicians and students!
