The son of a sporting goods merchant, Shrontz graduated from Boise High School in 1949 and the University of Idaho in 1954 with a Bachelor of Laws degree, where he was a member of the Beta Theta Pi fraternity. Following a commission and service in the U.S. Army from 1954-56, he attended the Harvard Business School where he received an MBA in 1958 and then joined Boeing.
Beginning in 1973, he served in the Nixon & Ford administrations at the Department of Defense, and returned to Boeing in January 1977 as a vice president. He served as CEO from 1986-96, and stepped down as chairman in 1997.
While serving on the board of directors for Chevron, a new double-hulled supertanker was named in his honor in November 1998.  The South Korean-built ship was renamed the "Antares Voyager" in 2003. 
Shrontz was inducted into the Junior Achievement U.S. Business Hall of Fame in 2004.
