Children's Oncology Services, Inc. (COSI) believes that a diagnosis of cancer should not prevent a child from experiencing the simple joys of childhood.

Through the magic of childhood experiences, we help kids diagnosed with cancer reclaim their lives. Our programs offer participants:

• diversion from their illness
• opportunities for success and control
• friendship and unconditional acceptance from those who understand
• information, answers and validation
• reasons to adopt a positive, "fighting" attitude
• something to look forward to
• memories that comfort when times are hard
• hope for the future

Dr. Edward Baum, a pediatric oncologist at Children’s Memorial Hospital in Chicago, founded Children’s Oncology Services, Inc., in 1978. Dr. Baum recognized that the isolation from school, activities and peers was having negative social and developmental consequences for his patients. With the help of friends and colleagues, Dr. Baum created COSI. The first summer, he and 14 volunteers welcomed 40 children with cancer to a life-changing week of hope, strength and support.

Today, COSI continues to be volunteer-driven, relying on more than 350 volunteers (including many former campers) to plan and operate a wide portfolio of camping, recreational and educational programs for children and adolescents diagnosed with cancer. From the popular two-week Summer Camp, which now serves nearly 300 children, to skiing excursions and education programs, COSI is a leader in providing empowering and fun experiences to young people facing cancer.
