PHOENIX - A Phoenix man has donated blood 600 times and saved more than 1,200 lives as part of a promise to his late wife.

James Van Dyne has been a dedicated blood donor for more than 30 years, making him one of the top 10 donors in the nation and the top donor in Arizona, according to a press release from United Blood Services.

When Van Dyne’s wife, Mary Lou, was diagnosed with cancer in 1985, he promised her he would give blood as often as he could, hoping to reach 500 donations in her honor.

Sadly, she passed away in 1989, but that hasn’t stopped Van Dyne from giving platelets every two weeks.

In honor of Van Dyne’s 600th donation, Gov. Doug Ducey has proclaimed Sept. 4-10 as Arizona Blood Donation Week.

Phoenix Mayor Greg Stanton also declared Sept. 8 as James Van Dyne Day to celebrate his lifetime of dedication to those in need.
