Blessing of Gianna Center

Women have more convenient health care options at Catholic Health’s Mercy Hospital. The health system celebrated the most recent addition to its new Women’s Health Center with a blessing of the Gianna Center at Rockville Centre, now located in the Ryan Building on the Mercy Hospital campus.  

The Women’s Health Center offers multiple women’s health specialties, including the new Gianna Center, which is a unique medical practice that offers women a restorative and natural approach to fertility as well as other women’s health issues. Gianna Center at Rockville Centre Director M. Jennifer DeMarco, DO, is board certified in family medicine and has been in practice since 2001. She is certified in NaProTECHNOLOGY (Natural Procreative Technology), which focuses on working cooperatively with a woman’s menstrual and fertility cycle. Catholic Health also offers Gianna Center locations in Manhattan and Babylon.  

According to Catholic Health’s Gianna Center Director Anne Nolte, MD, “While the Gianna Center cares for women with fertility challenges, our services also include restorative treatments focused on correcting the underlying problems for conditions such as endometriosis, hormonal abnormalities, and menstrual irregularities. In one setting, the center offers a team of women’s health specialists, which benefits patients who may need referrals for other interventions.” 

In addition to the Gianna Center, the new Women’s Health Center at Mercy also offers minimally invasive gynecologic surgery and urogynecology, featuring women’s health specialists who are board certified in obstetrics and gynecology, and have completed additional training in their respective specialty.

Peter Sticco, MD, is a fellowship-trained minimally invasive gynecologic surgeon specializing in laparoscopic and robotic procedures. He treats complex gynecologic conditions and focuses on the latest minimally invasive techniques. 

Catholic Health Division Chief of Female Pelvic Medicine and Reconstructive Surgery Keith Downing, MD, MS, MPA, FACOG, FPMRS is a urogynecologist, trained in pelvic medicine and reconstructive surgery. Dr. Downing specializes in issues related to the pelvic floor and bladder.

In 2021, the Women’s Health Center will also be expanding services to include a gynecology oncologist, a gynecologist trained in treating cancers of a woman’s reproductive organs.
