About Me

Since I was a young boy, I always wanted to be a doctor. I was highly influenced by my older brother who was a doctor, as well as family friends who also went to medical school. During my residency, I was fascinated by everything I learned during my rotation in gynecology and reproductive medicine, especially the endocrine system.

I treat patients with clinical conditions including ovulation disorders, endometriosis, recurrent pregnancy loss, and problems associated with advanced reproductive age. I also treat patients who have cancer, and we now have many options to preserve their fertility.

The procedures that my team and I perform regularly at NYU Winthrop Hospital include pelvic ultrasounds, biopsies, in-vitro fertilization, ovulation stimulation, egg donation, and fertility preservation procedures.

We are considered a Center of Excellence and are a well-known medical center on Long Island. We are devoted to our patients and treat them with dignity, compassion, and the utmost care. We treat them as we would want our loved ones to be treated—with respect and sensitivity to their needs.

We are involved in the research of various medical conditions such as reproductive failure, and evaluate data from our reporting to the Society of Assisted Reproductive Technology.
