Why we are the right choice for your care

Mather Hospital, a member of Northwell Health, is an accredited 248-bed, non-profit community teaching hospital. We are dedicated to providing the highest quality clinical care, educating current and future generations of healthcare professionals, promoting health education, and caring for the community regardless of ability to pay.


As members of the Mather Hospital Family—trustees, medical and hospital staff, volunteers and benefactors—we are committed to providing care to the best of our ability, showing compassion and respect, and treating each patient in the manner we would wish for our loved ones.


Our mission is to meet or exceed each patient’s expectations through the continued collaboration of every member of the Mather Hospital Family.

Patients first
Mather Hospital is committed to building positive relationships between our staff, our patients and their families. If you feel that a healthcare provider does not have your best interests at heart, or if a staff member does or says something that upsets you, please contact our Patient Experience Team at ext. 4416.
