Montessori Center School (MCS) has transformed its jog-a-thon tradition into a student-led service learning experience.
For the first time Jog-a-Thon 2025: Run for Glimmers Childhood Cancer Foundation will channel 100% of proceeds directly to pediatric cancer research and support services for families navigating childhood cancer diagnoses in honor of former student Ava Decker by highlighting her legacy foundation.
The event is inspired by and dedicated to Ava Decker, a former MCS student who was diagnosed in 2022 with osteosarcoma, a rare and aggressive form of bone cancer.
Ava’s journey with MCS began in infancy and continued through her elementary years, where her joy, creativity, and love of learning touched those around her.
“Ava was not only a student; she was a young changemaker,” the school said. “Before her passing in 2024, she founded the Glimmers Childhood Cancer Foundation to bring hope, support and awareness to other children facing cancer.”
Ava’s mother Vanessa Decker, a dedicated parent leader at MCS, chaired multiple school galas and worked closely with staff and families to support the school’s mission and build MCS community, the school said.
Today, Glimmers Childhood Cancer Foundation continues Ava’s mission of funding essential pediatric cancer research, directly supporting families undergoing treatment, and raising awareness to advance care for children affected by cancer.
“With the reimagined jog-a-thon, Montessori Center School is introducing a service learning model that empowers students to connect physical effort with civic action, according to Vanessa Jackson, head of school.
“Our students are not just running laps—they’re learning what it means to step up for others,” she said. “This service learning event is a tangible way to show Montessori Center School students the power of compassion and being positive changemakers in their local community.”
Funds raised through this year’s jog-a-thon will support Glimmers’ three key pillars:
• Funding cutting-edge pediatric cancer research
• Supporting children and families at UCLA Mattel Children’s Hospital
• Inspiring advocacy and awareness for childhood cancer care
