Award-winning stroke care you can trust
When you or a loved one has a stroke, you want to know you're in good hands. Lenox Hill Hospital has been a New York State Department of Health Designated Stroke Center since 2006—which means you can expect excellent care provided by highly trained and specialized stroke neurologists.

About us

The Stroke Center at Lenox Hill Hospital offers comprehensive, multidisciplinary care for stroke patients and their families. We are an award-winning stroke center that has received the Get with the Guidelines – Stroke Gold-Plus Quality Achievement Award from the American Heart Association/American Stroke Association (AHA/ASA) for implementing specific quality improvement measures that make sure that stroke patients receive the highest standards of care for thrombolytic treatment.

The hospital also received the AHA/ASA Target: Stroke Elite Honor Roll status for meeting stroke quality measures that reduce the time between hospital arrival and treatment with clot-buster tPA, the only drug treatment approved for stroke by the Food and Drug Administration.

Clinical expertise

Lenox Hill Hospital is committed to delivering the highest quality care available to stroke patients. The Stroke Center offers the most comprehensive, specialized and cutting-edge treatments for every type of stroke. In addition to our outstanding medical stroke specialists, the center brings together supporting physicians in other specialties and healthcare professionals, including:

  • Critical care specialists
  • Emergency medicine doctors
  • Neuro-interventionalists
  • Neurologists
  • Neuroradiologists
  • Neurosurgeons
  • Nurse practitioners
  • Occupational therapists
  • Physician assistants
  • Physical therapists
  • Speech therapists

We actively train all stroke team members and emergency medical technicians to quickly recognize and mobilize resources when a stroke patient comes to the hospital.

Patients who come in through our emergency room are quickly examined and given priority in all testing and diagnosis. Within minutes of a stroke code, our team performs a full patient assessment, rushes the patient to CT/MRI imaging and develops a treatment plan.

After the initial treatment, patients are monitored around the clock for neurological changes in the Stroke Unit, which is jointly managed by the Department of Critical Care Medicine and specially trained nursing staff.

The Lenox Hill Hospital Stroke Center offers 24/7 coverage and consultation, the latest stroke treatment options, and access to the latest clinical trials and research.

Why choose us?

Coordinated care. From the first point of contact through rehabilitation, we work hard to ensure our patients receive seamless care. The broad resources of the Stroke Center make it possible to communicate quickly and effectively with specialists throughout the facility to develop the best treatment plan for our patients throughout the continuum of their care.

Expertise. Our stroke specialists utilize the latest advancements in treating and preventing stroke, and are engaged in developing innovative treatments including neuro-interventional procedures for our patients. Our neurologists and neuro-interventionalists are nationally recognized for their experience in the field and patient outcomes.

Compassionate outreach. Knowledge is essential to diagnosing and preventing stroke. The stroke team at Lenox Hill Hospital actively engages the community to provide educational seminars on the signs and symptoms of stroke, as well as holding monthly support groups for stroke survivors and their families.
