Meet Your Breast Cancer Care Team

Huntington Hospital’s board-certified, fellowship-trained breast cancer oncologists, radiologists, and surgeons are a leading team, with a dedicated clinical support group fiercely devoted to fighting breast cancer.

Our program was founded in 1998 when several doctors from surgical oncology, pathology, medical oncology, radiation oncology, and breast radiology came together to establish an integrated program with the latest advances in diagnostic imagingbreast surgery, medical oncology and radiation therapy.

Today, our physicians are are also heavily involved with our support services, educational programs, and clinical trials for breast cancer patients as well as their families.

Through our partnership with the Jim and Eleanor Randall Breast Center, we offer expertise in breast MRI, CT, ultrasound and nuclear medicine.
