I am the chief of radiation oncology at Memorial Cancer Institute, where I care for patients with all types of cancer, including breast cancer, lung cancer, prostate cancer and lymphoma. I am also interested in treating head, neck, thoracic and gastrointestinal malignancies.

My grandfather was a physician in Nicaragua and inspired me to pursue a medical career. I decided to focus on radiation oncology due to a strong family history of cancer. I love having the ability to interact daily with patients and using modern advanced technology to eradicate cancer.

At Memorial, I educate patients on their cancer and the effectiveness and side effects of radiation therapy. I also listen to and address their questions and concerns about their cancer care and treatments.

I also enroll patients in numerous clinical trials, especially for the treatment of breast cancer, lung cancer and brain metastases. These trials make the latest treatments and protocols available for our patients in South Florida close to home. I’m also involved in committees and projects to improve quality care for all.

In addition to providing patient care, I present, publish and lecture on various aspects of radiation therapy and cancer treatment.
