“After working a year in central New York, this change reunites my family at home and provides a refreshed opportunity to advance healthcare in the Catskills and the Greater Hudson Valley. To say this feels like a homecoming is nothing short of an understatement,” said Schiller. “I am excited to return to Garnet Health and be part of an organization that works hard to meet the needs of the community and cares so deeply for the patients. I stand committed to serving the residents of Orange and Sullivan counties, ensuring that access to quality healthcare remains a top priority.” He continued, “I am also honored to be working with my friend and colleague Jerry Dunlavey once again. Jerry has made Garnet Health proud as interim president and CEO, and will make an excellent CEO for Garnet Health – Catskills.”

Schiller received a bachelor’s degree in human services at LeMoyne College and a master’s in health systems administration from Rochester Institute of Technology.
