For Jefferson, the merger continued its accelerated growth under Klasko. In 2012, the university and its three hospitals were a $1.3 billion operation with about 3,750 students, most at the graduate level. Now, it has twice as many students — about half undergraduate — and 14 hospitals operating on a $5.1 billion budget. Formerly landlocked in Center City, it also gained space on East Falls' 107-acre campus; a health sciences building will open there in 2019.
