Oncology Nurses

Members of the institute’s experienced nursing staff are nationally certified by the Oncology Nursing Society. Responsible for coordinating what is often a multidisciplinary treatment course, they begin by conducting initial assessments and medical history evaluations. These nurses follow patients on a daily basis and offer helpful teaching and medical intervention as needed throughout the radiation treatment course. They also provide continuity of care for patients and their families throughout the follow-up period. To contact, call 732-923-6890.

Simulator Therapists

Assisting physicians in the first step in the radiotherapy planning process is the major role of simulator therapists. Under computed tomography (CT) guidance to help target treatment, they are responsible for placing the markings on the skin where treatment will be targeted during upcoming therapy sessions. To contact simulator therapist Joseph Fennell, call 732-923-7970.

Registered Dietitians
