Owings Mills-based McDonogh School unveiled a $75 million capital campaign named McDonogh Forever, the largest undertaken by an independent school in Maryland. McDonogh officials said they have commitments of $58 million to date, including a $30 million challenge grant from the Rollins-Luetkemeyer Foundation. The campaign will fund priority construction projects, including a student life center for students K-12, with a lead gift from local real estate developer Edward St. John; a science, technology, engineering and math (STEM) building for grades 9-12, with a lead gift from alumnus Irvin S. Naylor; and an efficient energy plant serving the entire campus.
