Lancaster Country Day School Mini-THON® 2025

Join us on April 11, 2025

In the U.S., 16,000 children under the age of 19 are diagnosed with cancer each year – that’s one child about every 33 minutes.*

Four Diamonds is on a mission to conquer childhood cancer, and we are too. Dollars raised by Lancaster Country Day School support some of the nation’s leading laboratory and clinical research programs to better prevent, diagnose, treat and cure childhood cancer.

The collective impact of our fundraising also ensures that every Four Diamonds child, regardless of income, receives the highest quality of childhood cancer care without ever seeing a bill for that care. Since 1972, Four Diamonds has helped more than 4,800 children and their families.
