Advanced Practice Providers

Mount Sinai Health System Emergency Departments integrate both physician assistants (PAs) and nurse practitioners (NPs) in seven emergency departments and six urgent care centers across the greater metropolitan area. Our team of advanced practice providers (APPs) is ever-growing and now includes greater than one hundred and twenty providers. APPs work side-by-side with attendings, fellows, and residents. They are a vital part of our emergency departments, as they provide compassionate and high-quality care to patients in all different areas of the emergency department, including fast track, acute care areas, pediatrics, urgent care centers, and our critical care and observation units.   

The Department of Emergency Medicine is committed to the educational mission of the Icahn School of Medicine and invests in the APP’s education and training. Our team of APPs are utilized to their utmost abilities. They will continue to sharpen and enhance their skills through an ongoing series of didactic and hands-on training. This includes Grand Rounds, Journal Club/Case Reviews, and bedside ultrasound and SIM training. All activities are accredited by the American Academy of Physician Assistants (AAPA) for Category I CME credits. In addition to continuing education opportunities, our PAs regularly teach physician assistant students rotating through our departments. We also organize an annual conference, Hot Topics in Emergency Medicine for the APP. The conference features presentations from our team and in 2020, it went virtual and international with over seven hundred attendees.

The Mount Sinai Health System Emergency Department also provides APPs with opportunities for professional development by advancing their career beyond their clinical duties. The APPs in emergency departments across the system have taken on administrative roles while others are involved in a number of committees to improve and optimize systems and operations. For instance, our APPs play a major role in SAVI (Sexual Assault and Violence Intervention), observation unit operations, department redesign, monitoring of sepsis metrics, implementation of telemedicine, overseeing the patient experience, and hold a leading role in Women in Emergency Medicine. 

Our APPs also enjoy being a part of the community just outside of our hospital doors. They regularly organize collections for food banks and soup kitchens, collect gifts every holiday season for underprivileged families, participate in local high school career days, and provide medical education to underserved areas. In 2020, they organized and led a peaceful yet powerful White Coats for Black Lives march through Central Park.   

Our APPs play an active role both inside and outside of our departments. They present a united team committed to the health equity and well-being of all patients whose lives they touch.

Please see the names and contact information for our APP PA chiefs. Feel free to direct any questions you may have to them regarding our APPs and/or physician assistant or nurse practitioner positions here in the emergency departments within Mount Sinai Health System.
