Mark Yesitis is a 36-year-old San Francisco police officer from Campbell, California.
Yesitis is a San Francisco police officer and cancer survivor who works patrol as a field-training officer -- which means he hears "fat jokes" all the time. Sick of the stereotype that all cops hang out in doughnut shops, he wants to disprove that notion. Actually, Yesitis got into the police force so that he could help people, and he wants to continue inspiring others with his story. Just two years ago, he beat testicular cancer. This married father of two children is out to prove that anything – including weight loss -- is possible.
