My Story

On June 6, 2009, at the age of 21, I was diagnosed with stage IV lung cancer. Being a non-smoker, student-athlete, and otherwise healthy young woman, the diagnosis came as quite a shock. With faith, support, and love of my family and friends, I have made it through 20 (and counting) rounds of chemotherapy and will return to perfect health. 

I practice the powers of "The Secret" and proclaim: "JILL IS HEALTHY...think it, speak it, believe it!!!" Thank you for believing in this miracle with me.
