Dr. Slater’s leadership will further strengthen Mount Sinai Kravis Children’s Hospital as a destination for excellence in pediatric surgery.”
“It’s an honor to lead a division with such a strong tradition of excellence,” said Dr. Slater. “My goal is to build on that foundation by expanding innovative evidence-based approaches that not only improve surgical outcomes but also enhance the overall experience of care for children and their families.”
Dr. Slater emphasizes a multidisciplinary, family-centered approach, collaborating with pediatric specialists, anesthesiologists, nurses, and support staff to deliver comprehensive, personalized care.
