“My favorite part of Oncology is the patients and their loved ones. Getting to meet and learn each one's story and helping them through their individual journey is the most rewarding thing for me. Each journey is unique and it is an honor to be able to help guide them and their families by providing compassionate care. Oncology is truly fascinating with the ever changing drugs and therapy options focusing on the highest quality of life and best outcomes. ”
