Summary

  • I am a board certified medical oncologist with specialization in breast and women's cancers. I have been part of City of Hope team since 2007 and am currently the vice chair and professor of the Department of Medical Oncology and Therapeutic Research and co-director of the Breast Cancer Program.

    I love working with women; they’re amazing people. They get a diagnosis that is, at times, potentially fatal, and manage to get through it while still taking care of their families and kids, coming out the other side as stronger people.
