I am a board-certified general surgeon and surgical oncologist, in practice for more than 25 years. I specialize in minimally invasive techniques, palliative surgeries and the treatment of cancerous tumors. I have published more than 30 articles in high-impact peer review medical journals and have authored five book chapters.

I serve as the physician coordinator for Cancer Initiatives Surgery at Mount Sinai Queens, where I am dedicated to treating patients with focused, individualized care and with compassion.
