Ollie's Orchestra

We are, of course, heartbroken by the recent loss of Ollie; the namesake of our organization. We know that his spirit lives on through the programs provided through Ollie’s Orchestra. We continue to push forward with our mission of providing music resources of all kinds to children with cancer diagnoses.

Music was an integral part of Ollie’s entire cancer journey. From engaging with an ocean drum during his first music therapy session in the hospital, to having dozens of musicians come and play for him while inpatient, to weekly music therapy sessions in-home to assist in his development during his periods of stability. Music was Ollie’s medicine and motivator throughout his life.

Here, Ollie can be seen with his music therapist, Sarah: smiling, attentive, communicating, and even saying new words. These are just a few snippets into the magic brought on by Ollie engaging in music activities and with musical instruments. Here at Ollie’s Orchestra, we want to be able to provide that magic to all children experiencing the horrors of cancer.

Help us keep Ollie’s legacy and love of music alive by donating today. 100% of your donation will go towards our mission statement.

Our heart, soul and inspiration, Oliver David Horn, who we affectionately called Ollie died at home, in his bed with his mom and dad next to him on April 29, 2026. Ollie was born on July 11, 2018, right in the middle of Rachel and Max’s birthdays. From birth, Ollie was always a bright, sunny child. He rarely cried unless he was hungry, never ever napped and had a complete adoration for books from a young age. His favorites included the Hungry Caterpillar, Jamberry, Caps for Sale, the Little Blue Truck and many more. Ollie loved to smile.

When Ollie was 9 months old, he was diagnosed with a rare and aggressive cancer of the brain and spine, AT/RT. Despite a dismal prognosis, Ollie defied every odd for over 7 years. He was a unicorn and forged his own path. The treatment for his cancer was so aggressive that it left him with many disabilities, yet that never stopped Ollie. He fought for the abilities many take for granted. Every new skill he gained, every new word he signed was always celebrated by himself and all of us around him who loved him. He worked hard and was proud of all he accomplished.

Ollie gave us 5 years of stability, something that was very much not expected when he suffered his third relapse in 2021. Despite all the odds Ollie enjoyed five magical years. He went to school, took weekly horseback riding lessons, enjoyed swimming and tried skiing. Most importantly, he had the chance to make amazing memories with his 3 little brothers, Benji, Miles and Levi. His brothers were the love of his life.

The other great love of Ollie’s life was music. Ollie especially loved the cello, with Bach being an absolute favorite. His legacy and the joy he found in music lives on with Ollie’s Orchestra. The nonprofit has gifted children and adolescents impacted by cancer with musical instruments and education.

Ollie is survived by his parents, Rachel Krieger and Max Horn, his brothers Benjamin, Levi and Miles and his cat Luna. He showed everyone he met how to enjoy life. He never complained about his challenges and instead taught us all to cherish life. Ollie is forever loved.
