Faber served as the Maryland lacrosse coach from 1928 to 1963, during which time he compiled a 249–57 record and secured numerous national and conference championships.

[6][7] During World War II, Faber joined the United States Army and served from 1942 to 1946, attaining the rank of major.

[1] He spent three years working at the Walter Reed Army Medical Center in Washington, D.C.[6] While teaching bacteriology at Maryland, Faber also held coaching duties.

[1] In 1955 and 1956, Faber led Maryland to back-to-back 11–0 seasons, with the only close matches coming against period powerhouse Navy, in 1955, and the highly successful Mount Washington Lacrosse Club, 12–11 in 1956.

[15][16] In 1930, Faber enticed Bosey Berger, Maryland's first basketball All-American, to join the football team with the promise of free late night dining hall meals.

Faber continued to employ his predecessor's pass-oriented "Byrd system" and hired Richmond head coach Frank Dobson as an assistant.

[18] Despite facing "an almost suicidal schedule",[19] Faber's veteran team led by back Bill Guckeyson compiled a 7–2–2 record to finish in third place in the Southern Conference.

[20] The coaching trio was subsequently replaced by Clark Shaughnessy, who two seasons prior had orchestrated a remarkable one-year turnaround at Stanford using a revolutionary version of the T formation.
