What I Love About My Job

 “No one ever wants to hear they have breast cancer. Those words can be life-changing and create a very scary and unnerving time. My goal is to help you through your journey and make this time as easy and peaceful as possible for you and your family. From the first abnormal mammogram or exam through treatment and on to survivorship, I will focus on compassionate care, a comprehensive understanding of your plan, and state-of-the-art treatment to help you fight your battle with confidence.”
