Guests of today's event got to meet a very brave young girl: 4-year-old Zoiey Gaines who has an incredible story to tell.
Coordinators of the Yuma blood drive hosted 65 local drives last year, providing more than 2,000 donations for patients all over Arizona.
Last July, Zoiey's dad says her energy began to drain.
She started having fevers, swollen lymph nodes, and unexplained bruising.
When the tests came back, Gaines' nightmare became reality. Zoiey was diagnosed with leukemia.
Since her diagnosis, she has received nearly a dozen blood transfusions and multiple rounds of chemotherapy to fight the cancer.
Zoiey was the special guest at Friday's United Blood Services luncheon honoring the coordinators of the Yuma Blood Drive.
She serves as a living reminder that donating blood can save a life.
Gaines says this journey has created a special bond between him and Zoiey.
Zoiey's treatments are expected to continue until October 2015.
Zoiey has the most common form of childhood leukemia and about 90% of patients younger than five years old are cured with treatment.
