David Archer, Roger J. Weiss ‘61 Head Coach of Football, Cornell University

david-archerDavid Archer (Ithaca, NY) is the head football coach at Cornell University and is the nation’s second youngest Division I head football coach (by three days). His career at Cornell began as a player and senior captain of the team in 2004.

After graduation, David spent time coaching high school in New Jersey as part of the Teach for America program before returning to Cornell as an assistant coach and today the Roger J. Weiss ‘61 Head Coach of Football. As alumni, boosters, and administrators are fond of saying at Cornell, Archer has seemingly always bled Big Red.

Integrating many of the concepts of Peak Performance Mind Coaching into his coaching practice, David offers a visionary approach to life both on and off the field. He has provided steadfast leadership while making education his mission — in football, in the classroom, and in life away from Cornell.

When he speaks about how Big Red football has shaped his entire life, it is easy to understand why success is coming to David personally and to the entire program in the years ahead.

David is a native of Endicott, N.Y.
