The projects aim to provide more advanced medical services to residents of the South Shore, who previously may have had to travel for certain types of care, according to hospital statements and news reports.
Key components of the expansion include a new four-story, $155 million Feil Family Pavilion that will add 40 new critical care beds, Newsday reported. In early October 2026, the hospital opened five of nine new, larger operating room suites designed to accommodate bigger surgical teams and advanced technology like robotic assistants. The new suites will allow the facility to begin offering open-heart surgery. The expansion also includes a $10 million investment for 24/7 advanced stroke care featuring a new biplane imaging suite, according to Newsday.
He joined Mount Sinai South Nassau in 2001 as an emergency medicine physician, according to the hospital’s website. His previous roles include serving as chief medical officer from 2007 to 2009 and, most recently, as Integration Officer. According to The Jewish Star, Kugler said his focus will be on continuing the growth of advanced services while preserving the hospital's community-focused culture and ensuring the safety and wellbeing of patients and staff.
Kugler’s predecessor, Sharma, was the first physician to lead the hospital in its history, HealthLeaders Media reported. During his tenure, which began in 2021, Sharma provided executive oversight for the $500 million expansion, according to a release from the Family & Children’s Association. He was also credited with guiding the hospital’s response to the COVID-19 pandemic as chief medical officer.
