Board Certifications

Radiation Oncology

I am a board-certified radiation oncologist with more than 20 years of experience. I care for people at Memorial Sloan Kettering and Norwalk Hospital and am Chief of Radiation Oncology at Norwalk Hospital. I have cared for nearly 4,000 men with prostate cancer using advanced minimally invasive technologies. These include radioactive seed implantation, called brachytherapy, and image-guided radiation therapy. Through my leadership roles and contributions in clinical medicine, research, and education, I have established an international reputation for excellence in treating prostate cancer.

I recognize the importance of caring for the whole person. My patients’ physical and emotional well-being are my top priority. I am firmly committed to ensuring that all levels of their experience and care are delivered with quality, compassion, and empathy. This is elevated by a collaborative multidisciplinary, evidence-based approach with my patients, their loved ones, and all members of their healthcare team.

I recognize the importance of caring for the whole person. My patients’ physical and emotional well-being are my top priority.
