Valley–Mount Sinai Comprehensive Cancer Care’s Gynecologic Oncology program is committed to delivering the highest level of oncology care to women in northern New Jersey. Our exceptional team includes medical oncologists and nurse practitioners who specialize in treating all types of gynecologic cancers — including cervical, uterine and ovarian cancers — with precision, compassion and an intimate understanding of women’s unique needs. 

Director, Gynecologic Oncology


Marie Welshinger, M.D., FACOG, Director of the Gynecologic Oncology program, is board certified in gynecologic oncology as well as obstetrics and gynecology. Dr. Welshinger believes in a holistic, team-oriented approach to care. In addition to delivering the best possible care for each of her patients, Dr. Welshinger makes it a priority to get to know her patients on a personal level and help them address their overall health. She is also a talented surgeon, skilled in minimally invasive techniques including robotic surgery.

Before joining Valley, Dr. Welshinger was Director of the Division of Gynecologic Oncology at St. Peter's University Hospital in New Brunswick. Following her fellowship at Memorial Sloan-Kettering, she practiced at the Carol G. Simon Cancer Center in Morristown, and subsequently was the Director of the Division of Gynecologic Oncology at New York Hospital Queens.

Dr. Welshinger sees patients at the Robert and Audrey Luckow Pavilion in Paramus. To make an appointment, please call 201-634-5401.
