Campers include children undergoing therapy for cancer or blood disorders, and those who have completed treatment. Children in remission share the camp with newly diagnosed children. Regardless of the age of diagnosis, they all share a common bond. Approximately half of the children who attend Camp CoHoLo receive medication for their condition. The volunteer staff at Camp CoHoLo includes pediatric hematology/oncology physicians and nurses from the Nebraska Medical Center and Children's Nebraska who maintain strict medication schedules and monitor the health of all campers.
