Rebecca Nelson, a retired TO manager and double-lung transplant recipient, works hard to stay healthy by participating in five Zumba classes every week. She worked at Hill Air Force Base for 12 years and received her transplant in July 2012. She has faced a long road to recovery, but with the support of her co-workers, family and Zumba classmates, she’s lost 30 pounds and is on a healthy track.
