The current campus, located off Douglas Avenue in the northern section of town, was opened in 1962 after moving from the previous location, now the site of Brewton Elementary School, less than one mile south. The school consisted of three wings of classrooms, a lunch room, a gym, a choir room, an art room, and an office area. The school was expanded to include a fourth wing consisting of four science classrooms in 1994. More recent additions include an auditorium and band room, a field house for the football program, a new gym, and a new football practice field, track, and concession stands. In 2013, the lunchroom and two wings of classrooms were demolished. In 2014 a new wing consisting of sixteen classrooms and a lunchroom was completed. In 2014 construction also began on a second wing which would include more classrooms, a media center, and an office area. It was completed in 2015. The auditorium, band room, art room, choir room, two gyms, science wing, and field house were not torn down and are still in use. Renovations to the football stadium began in 2015 and included updates to the home bleachers, a new press box, and a new scoreboard. Renovations to the baseball field also began in 2015 and included new dugouts, new batting cages, a new scoreboard, and eventually new bleachers.

The men's basketball team brought home a mythical state championship in 1952, which is to date the only championship the boys basketball program has won.

Miller graduate turned head coach Jamie Riggs. Under Riggs the Tigers won four state titles. The T. R. Miller football team was considered to be "the winningest football team of the 1990s" in the State of Alabama. In 2015, Riggs won his 300th coaching victory, becoming one of only four coaches in the state to achieve that milestone. On December 14, 2015 Riggs announced his retirement.
