He also supported the creation of the Institute for Critical Care Medicine across the Mount Sinai Health System.
“Jonathan’s track record in operational excellence, strategic planning, and high-quality patient care aligns perfectly with the mission and goals of RWJBarnabas Health and Jersey City Medical Center,” said Thomas A. Biga, Executive Vice President and President, Northwest Region. “His leadership will be instrumental in expanding services in Hudson County.”
