Additional Information

Dr. Onesti is a board certified surgical oncologist who specializes in caring for patients with cancers of the gastrointestinal tract. As medical director of the surgical oncology department at Mercy Health Saint Mary's, she founded the HIPEC program in 2015. Since then, the team has worked closely with the gynecologic oncology department to provide comprehensive treatment of ovarian and peritoneal cancers as well. Each patient receives support from his or her own personal nurse navigator and is presented to a multi-disciplinary team, including medical oncologists, radiation oncologists, interventional radiologists, gastroenterologists, nutritionists, social workers, research members, and others. Consultations and second opinions are available.

"I chose surgical oncology because I witnessed the difficult journey that many patients encounter. I felt God leading me to focus on these individuals to combine a strong support system with the newest technologies, while keeping the patient at the center of our goals." - Dr. Onesti
