Mount Sinai Beth Israel A teaching hospital founded in 1889 on Manhattan's Lower East Side, Mount Sinai Beth Israel is notable for its unique approach to combining medical excellence with clinical innovation. We have recruited world-class specialists to expand services in heart disease, cancer, neurology, and orthopedics. We also continue our long tradition of excellence in medical specialties, including gastrointestinal disease, chemical dependency, psychiatric disorders, pain management and palliative care, and HIV/AIDS research and treatment. We have also significantly advanced our commitment to community-based ambulatory care and expanding patient access to primary and specialty care.
