Meet the Cancer Patient Navigators

Patient Navigator

Tonica Anderson, RN, BSN, OCN
618.985.3333 ext 68305 |

Tonica has a diverse background in nursing, which includes several years in oncology, as well as an OCN certification. She previously worked in home health & hospice for several years, then in community outreach and education. She is a member of the Illinois Cancer Partnership Executive Committee and has worked at the SIH Cancer Institute since 2009, just after her mother was diagnosed with bladder cancer. All of these experiences led Tonica to choose to become a cancer patient navigator.

“I have seen firsthand how devastating hearing the words ‘you have cancer’ can be not only to the patient but also to the family. As a navigator, my goal is to make what is typically considered a really bad time in someone’s life a little bit easier.

Diane Clayton, RN, OCN
618.985.3333 ext 67133 |

Diane Clayton, OCN, has been with Southern Illinois Healthcare for 18 years, serving primarily in Radiation Oncology. While her daily work meant interacting with patients and families as they go through a cancer diagnosis, she was most impacted by her father’s lung cancer diagnosis in 2013. His experience opened her eyes to see firsthand that care does not stop after an eight hour day.

“That event is why I chose to become a cancer patient navigator. My goal is to provide you the best care for my patients and family members. I will be your advocate as well as your partner. You are not alone – together we will take this journey.”
