Stony Brook Medicine has named a new chief administrative officer for its Southampton Hospital campus. Emily Mastaler, coming from her previous role of president and chief executive officer of River Hospital in Alexandria Bay upstate, has "extensive healthcare knowledge, clinical expertise, and ability," the hospital said in an announcement on Wednesday.

"She will play a vital role as we continue to grow and deliver on our commitment of providing access to Stony Brook Medicine's medical experts, specialists, and services throughout all our East End communities," Carol Gomes, Stony Brook University Hospital's chief executive officer, said in the announcement.

Ms. Mastaler holds a master's degree in business administration from Northeastern University, a master's in psychology from Antioch University, and a bachelor's degree in psychology from Elmira College. Over her nearly 20-year career in health care administration, she has held several positions, including clinical roles and that of chief operating officer for Health Care and Rehabilitation Services of Southeastern Vermont.

For River Hospital, she was credited with creating "a highly successful strategic plan," guiding "operational success" during the Covid-19 pandemic, and obtaining philanthropic support for its first-ever endowment campaign, according to Stony Brook.

She succeeds Bob Chaloner, the popular chief administrative officer at Southampton Hospital and Stony Brook Southampton Hospital, who held that role for a combined 16 years until he stepped down in March 2023. Dr. Fredric Weinbaum had been serving in an interim capacity since then, and will now continue working as chief medical officer and chief operating officer of the hospital.

"I am truly honored for the incredible opportunity to join the Stony Brook Medicine and Stony Brook Southampton Hospital team," Ms. Mastaler said. "I am strongly aligned with their unyielding commitment to the sustainability of exceptional healthcare within a diverse community."

At Southampton, she is expected to implement and supervise policies and procedures to ensure the smooth operation of the hospital. 

"Throughout Mastaler's career, she has been committed to cultivating diversity, inclusion, and health equity," William Wertheim, the interim executive vice president of Stony Brook Medicine, said. "We look forward to her becoming a champion for change who promotes initiatives that serve the very diverse eastern Long Island community."
