Kemper Goodwin, a prominent local architect, would go on to graduate from Tempe High in the mid-1920s, then design its current campus in the 1950s.

In 1953, the current Tempe High School opened with the administration and library buildings; three classroom units; and the cafeteria.

To celebrate this momentous occasion, a Centennial Committee was formed under the wing of the Tempe High Buffalo Foundation.

This organization helps preserve the proud traditions and history of Tempe High and serves as an alumni resource for reunions and fundraising events.

Centennial events included: Athletic Hall of Fame dinner, Homecoming parade down Mill Avenue, Back to the Future celebration, and the Embassy Suites Blue and White Bash.

In the final playoff game in Sun Devil Stadium, which was attended by more than 11,000 fans, the Buffaloes and the Owls fought to a 10–10 draw.

In 1989 one of the greatest football games was played between the two schools, more than 10,000 fans were in attendance to watch Tempe High defeat McClintock 25–24.
