Support Services


Marthia NicholsMarthia Nichols, RN, MSN, MHA

Marthia N. Nichols is the Patient Navigator at the Cheryl R. Lindenbaum Comprehensive Cancer Center. Marthia is a certified oncology nurse and holds a Master’s of Science in Nursing and a Master’s of Healthcare Administration. She has been an oncology nurse for six years and has a passion for women’s health. Becoming an Oncology Patient Navigator was a natural career choice for Marthia, who became a nurse after caring for her own father throughout his battle with cancer. “Everyone deserves an advocate for their health care needs especially, when your life depends on it,” she said. Marthia enjoys gardening.

The role of the Nurse Navigator is to assist patients in understanding their diagnosis and treatment, facilitate their work up and treatment schedule and to identify patient and family needs for support and community resource referral.  The average patient with a suspected or known cancer diagnosis is faced with appointments and information from no less than five specialists as well as information and advice from well-intended family and friend and the media.  In a time of crisis, this is truly overwhelming and can delay treatment and follow-up while patients and families sort through the information.  The role of the Nurse Navigator provides that one point of contact for clarification of information, coordination of care, reinforcement and support. Marthia can be reached at 914-293-8402.
