Gerard J. Pregenzer, MD, FACOG, FACS, FICS, FAACS, ACGE


Gerard Pregenzer MD, completed his medical training at the prestigious Columbia Presbyterian Medical Center in New York. He has over 25 years of experience in the care of the obstetrical patient and has been the recipient of numerous awards including the Alpha Omega Alpha (AOA) National Medical Honors Society award, Columbia Presbyterian Medical Center Howard C. Taylor teaching award, the March of Dimes research award, member of the esteemed “One Kilo Club” and recipient of the ACOG Film Festival Award 2008 for excellence in surgery.

He is a Fellow in the American College of Obstetricians and Gynecologist, the American College of Surgeons, the International College of Surgeons, the American Academy Cosmetic Surgeons. He is also a member of the American Institute of Ultrasound In Medicine, American Society of Laparoscopic Surgeons, and the American Academy of Age Management.

Dr Pregenzer has been interviewed numerous times on TV and in local and national newspapers and has been invited to perform surgery internationally. He was one of the first physicians in New Jersey to have the vision of the important applications that an electronic medical record can have in the field of medicine. He has been involved with the development of an ideal medical record for the obstetrical and gynecologic patient for the past nine years. Dr Pregenzer believes that such a medical record, as developed by VerifyIMI will dramatically improve the delivery of safe and efficient obstetrical care for both patient and physician.

I assist Dr. Pregenzer in preparing his patients for their appointments. Our care for our patients does not end once you leave our office. We encourage patients to contact us with any questions, concerns, or further clarification from previous visits. I will do my very best to address your question or use all of my resources to get a response for you.



Born January 27th, 2016. I’ve been coming to Women’s Health Care since before I was born. I still like to come to the office and visit with patients. Sometimes you might hear me giggling in the back office even if you don’t get to see me. I visit the Dr. Salvatores down the hall too so you might even see me there. Grandma takes me to the playground every day and I love to eat soup afterwards! I have a dog, 2 cats and a tortoise that I love to take care of and talk about.
