About Us

Clinical excellence and compassionate support are the foundations for Arizona Blood and Cancer Specialists.

Our team of medical oncologists / hematologists and radiation oncologists treats all types of cancer and blood disorders, and our breast surgeon treats patients with breast cancer or a non-malignant abnormality of the breast.

We provide patients with a full continuum of cancer care, including medical and radiation oncology, diagnostic imaging, hematology, and palliative care.

Having an office at Lambert and La Canada in Oro Valley means that Arizona Blood and Cancer Specialists can best provide personalized treatments and compassionate care for patients in Northwest Tucson, just minutes from Oro Valley Hospital and Northwest Medical Center. It’s especially important for our patients that they are close to their support system of family, friends and caregivers while receiving their care.
