About Northwell Health

Northwell Health is a nonprofit integrated healthcare system providing hospital care, physician services, outpatient treatment, emergency care, medical research, education and other healthcare services. The organization serves communities across New York and Connecticut and operates a broad network of hospitals, ambulatory facilities, medical practices, laboratories and specialized clinical programs.

Northwell Health’s modern organization traces to the 1997 merger of North Shore Health System and Long Island Jewish Medical Center, which created the North Shore-Long Island Jewish Health System. The organization later adopted the Northwell Health name in 2016. It has since expanded through hospital affiliations, physician-group growth, outpatient facilities, research programs and medical education.

Northwell Health is headquartered at 2000 Marcus Avenue, New Hyde Park, New York 11042. Current 2026 career information describes Northwell as the largest not-for-profit health system in the Northeast, with 28 hospitals, more than 1,000 outpatient facilities and more than 100,000 team members. Northwell is a nonprofit organization and does not have publicly traded stock or a conventional shareholder Investor Relations department.

How to File a Complaint Against Northwell Health

Patients or family members experiencing a concern involving medical care, billing, staff behavior, communication, access to services or another Northwell matter should direct the complaint to the facility responsible for the care whenever possible.

Step 1: Contact the Care Team

For an active care issue, begin with the physician, nurse, office manager or department responsible for the patient’s care.

Explain the concern and ask what can be done to resolve it.

Step 2: Ask for Department Management

If the first person cannot resolve the concern, ask for the nurse manager, practice manager, department supervisor or another appropriate leader.

Step 3: Contact Patient Relations

For a hospital complaint, contact the Patient Relations or Patient Experience department at the hospital involved.

These teams are specifically responsible for helping patients and families address healthcare-service concerns.

Step 4: Document the Issue

Keep relevant dates, facility names, physician names, bills, letters and other records associated with the complaint.Do not include unnecessary medical information in unsecured email.

Step 5: Request a Case or Reference Number

If the facility creates a complaint case, save the reference number for future follow-up.

Step 6: Follow Up With Patient Relations

If the matter remains unresolved, contact the Patient Relations department again and provide the previous case information.

Step 7: Contact Billing Separately When Appropriate

For a billing concern, use the number printed on the Northwell bill or statement.
