Olivia, along with lead oncologist Dr. Robert Rupert and Jenna Hoffman, CNP, sees patients at two locations – Memorial Hospital’s main campus as well as at the Memorial Urbana Medical Center.

Together, the team works to provide a continuum of care for patients diagnosed with cancer or malignant/non-malignant blood disorders. For those within their cancer journey, the providers will focus on treatment option plans, nutritional guidance, patient education, in addition to continual oncological care. This team approach will also include pharmacists, patient navigators, and dietitians, to help round out the care.

Olivia has been serving hematology/acute leukemia patients for over 10 years, most recently at The James Cancer Hospital & Solove Research Institute. She has her Master of Science in Nursing with an Adult-Gerontology Acute Care Nurse Practitioner specialty from The Ohio State University. She also has her Bachelor of Science in Nursing from Bowling Green State University.

Originally from Richwood, Olivia loves this region and is excited to be at Memorial. She feels a special bond to this community and is devoted to caring for her patients who are battling oncological or hematological conditions. Olivia and her husband have two children and together they live on a mini-farm in Ostrander. She loves to garden in her flower beds as well as swim and hang out at the pool with her family.
