At just 11 years old in 2010, Cassidy was diagnosed with GBM. She underwent surgery, radiation, and chemotherapy and went on to live a normal teenage life. Unfortunately, her disease recurred at age 20, and she underwent surgery, radiation, and chemotherapy again. Although stable, the radiation caused a severe side effect called radiation necrosis, which left the right side of her body numb and severely impaired. She also experienced significant speech difficulties. Despite these challenges, Cassidy adapted and opened her own floral business, Purple Petals. Through her incredible resilience, she found a way to create beautiful arrangements using only one hand.

In last September, Cassidy suffered a severe seizure and was hospitalized. Her biopsy classified her tumor as a DMG. Although there was initially hope that three chemotherapy treatments could control the disease, Cassidy passed away peacefully surrounded by her family, on January 29, 2026.
