In 1948, Stribling directed the reorganization of the academy into a nonprofit educational corporation governed by a board of trustees of alumni, faculty, and friends.

A member of the faculty for 16 years, Stribling III had served as teacher, coach, commandant, executive officer, and director of alumni affairs, development, and public relations.

The administration building, built in 1900 and a historical focal point of the campus, was renamed Stribling Hall by the board of trustees in 1981 in honor of his contributions to the academy, the community, and the nation.

[3] Stribling III was succeeded as MMA president in 1993 by Ronald Kelly, a faculty member since 1969 who had served as a teacher, coach, advisor, director of admissions, and executive officer.

After the 2006–07 school year, Kelly was succeeded by Robert Flannigan, a retired U.S. Marine Corps major general who had been business advisor and commandant of Admiral Farragut Academy in St. Petersburg, Florida.

He came to MMA from McGeorge & Co., a limited liability company he founded in 2010 to provide consulting services to independent schools and colleges.

In 2003, the academic program was expanded to include dual-credit courses, allowing cadets to accumulate college credit hours while fulfilling high school requirements.
