Our Nurses

---

We have been blessed to work closely with some of the most experienced nurses in the South Shore of Long Island. Our staff comes from a background in emergency medicine, critical care, and interventional cardiology. They are an integral part of our stroke care team, and a major reason behind the Stroke & Brain Aneurysm Center’s success on Long Island.

Our expert endovascular procedural nurses are Michelle Grippo, RN, Michelle Abbatiello, RN, Sharon Johnston, RN and Rob Mussachio, RN.

Some of the Stroke & Brain Aneurysm Center’s Nursing Staff can be seen in the picture below with Dr. Bekelis and Jason Wallen. Featured from left to right you can see Rob Musacchio, RN, Michelle Grippo, RN, and Sharron Johnston, RN
