As chief medical officer, Dr. Palumbo oversees nearly 1,500 physicians and all clinical operations, leading initiatives to advance quality, safety and patient experience across the hospital and its ambulatory network. He is highly visible and accessible to staff, with regular physician meetings and a consistent on-site presence. He also oversees two internal newsletters to keep employees informed. He joined White Plains Hospital in 2005 as the founding medical director of the adult hospitalist program, growing it from four physicians to nearly 60 hospitalists across multiple specialties, and he was named executive vice president and medical director in 2009 before becoming chief medical officer in 2018. His contributions include involvement in major service expansions such as the 2021 launch of the Montefiore cardiac surgery program, which brought open-heart surgery to the hospital. He also led the 2023 appointment of an executive director of neurosciences, the 2023 launch of the Montefiore structural heart program with transcatheter aortic valve replacement, and the 2025 addition of the ION robotic bronchoscopy platform to support earlier lung cancer diagnosis. Additional leadership roles include board service with Hospice of Westchester and Burke Rehabilitation Hospital, both in White Plains.
