Poling was trained as a wrestler by Larry Sharpe. He debuted in 1990, wrestling on the independent circuit under the ring name "Al the Sledgehammer". In 1994, Poling won the Pro Wrestling Illustrated Rookie of the Year award.
Poling achieved his greatest national exposure in Extreme Championship Wrestling (ECW) in the mid-1990s. He debuted in ECW as a "handler" to Sabu. Later his gimmick was as an enforcer of the "extreme" attitude; he was named 911 and joined Paul Heyman's Dangerous Alliance stable with Sabu and Tazmaniac. As part of his monstrous persona, he would frequently perform the chokeslam on others with little provocation. At 1994's NWA World Title Tournament, he defeated Doink the Clown after four chokeslams. Poling left the promotion by early 1996 after a falling out backstage with Heyman over the former's treatment of the ring crew. Poling returned at ECW UltraClash 1998 in Philadelphia, Pennsylvania, chokeslamming Bill Wiles. Poling was then accompanied by manager Judge Jeff Jones, who proclaimed 911 to be the true giant of professional wrestling. They were then interrupted by Spike Dudley and had an impromptu match, which 911 lost in under a minute.
Poling wrestled in World Championship Wrestling (WCW) in 1996 and 1997, under the names Tombstone, Sledge Hammer and Big Al. Poling did not portray the Big Al who appeared in WCW in early 2000.
Throughout the late 1990s, 911 appeared with the New Jersey based Jersey All Pro Wrestling promotion, winning the JAPW Heavyweight Championship on two occasions. At Hardcore Homecoming in 2005 he chokeslammed both Danny Doring and Roadkill. He wrestled at New York Wrestling League in 2008.
