Technology and Services

Since its inception more than two centuries ago, Mass General has remained at the forefront of medicine by fostering a culture of innovation. We have made tremendous contributions to the development and refinement of information technology for clinical care, research and education, and have invested in a variety of techniques to improve the quality and safety of patient care. Today, Mass General offers sophisticated diagnostic and therapeutic services in virtually every specialty and subspecialty of medicine and surgery. We admit over 51,000 inpatients and perform more than 1.5 million outpatient and emergency room visits each year. Mass General sponsors graduate medical education in 17 core specialties and more than 90 subspecialties, including:

  • Anesthesia

  • Surgery


The Mass General campus includes 25 buildings in Boston's West End, as well as several outpatient facilities located offsite. As a world-renowned research institution, the hospital operates over one million square feet of research space in Boston, Cambridge and Charlestown, with a budget of $928 million in 2018. Taken together, the Mass General campus constitutes Harvard Medical School's largest teaching and research site.

Several structures embody Mass General's collaborative approach to science and medicine. Opened in 2011, the Lunder Building not only increased the hospital's inpatient capacity, but co-located and enhanced services in cancer, neuroscience, radiation oncology and emergency services. The Richard B. Simches Research Center, which accounts for 25% of the hospital's total research space, houses four thematic research centers designed to foster new and exciting partnerships among scientists from different disciplines. Similarly, the Yawkey Center for Outpatient Care centralizes ambulatory services under one roof, cultivating clinical collaboration and access to multiple disciplines. In 2009, the Ragon Institute was established through the generous support of the Phillip T. and Susan M. Ragon Foundation. It has created a model of scientific collaboration that links the clinical, translational and basic science expertise at Mass General, MIT and Harvard to tackle the greatest global health challenges related to infectious disease research.
