Pommerening was born in Ann Arbor, Michigan, in 1904. He was the son of August Pommerening and Mathilde Pommerening. His father was an immigrant from Germany and a construction worker.
Pommerening attended the University of Michigan. He played on the freshman football team in 1924 and the varsity football team from 1926 to 1928. During the 1928 season, Pommerening became the first player in the history of the Big Ten Conference to play every minute of every game for his team. One wire service report noted that he set the endurance record despite having suffered a severe head injury early in the season. An Iowa newspaper credited Michigan's "big tackle" Pommerening as one of the players deserving credit in Michigan's 10-7 win over Iowa in 1928. The paper wrote that Pommerening "ripped wide holes in the Iowa line as Michigan started their winning drive." Pommerening was a consensus first-team All-American for his play at tackle in 1928. In December 1928, the United Press named Pommerening to its All-American team at tackle, noting that Pommerening, "in a weak Michigan line stood out as the greatest in many a 'Big Ten' season." He was listed at 5 feet, 11 inches, and 178 pounds. Pommerening also finished fourth in the voting for the Chicago Tribune Silver Football trophy, awarded to the most valuable player in the Big Ten Conference. He also was selected as the most valuable player on the 1928 Michigan Wolverines football team and is regarded as one of the best linemen ever to play for the Michigan Wolverines. Pommerening had hoped to play in 1929 but was ruled ineligible in November 1928 because he played five minutes in a game against Oklahoma A & M during his sophomore year.
