He debuted in ECW as an unnamed "handler" to Sabu on January 18, 1994 by defeating Chad Austin. He joined Paul Heyman's Dangerous Alliance stable with Sabu and The Tazmaniac. His gimmick was as an enforcer of the "extreme" attitude; he was named 911 at The Night The Line was Crossed on February 5, where he defeated Chad Austin in a rematch. As part of his monstrous persona, he would frequently perform the chokeslam on others with little provocation, which made him quickly popular with the crowd as a fan favorite. He received his first title shot in ECW at When Worlds Collide, where he challenged Mikey Whipwreck for the ECW Television Championship but got disqualified after chokeslamming the referee. He would then enter a rivalry with Mr. Hughes, whom he defeated at Hardcore Heaven. He closed the year by defeating The Pitbulls in a handicap match at Holiday Hell.
911 had two big matches in 1995, scoring wins over Ron Simmons at Hostile City Showdown and Jim Steele at Barbed Wire, Hoodies and Chokeslams. At the 1996 House Party event, 911 teamed with Rey Misterio, Jr. to defeat The Eliminators in a tag team match, which would turn out to be his last match in ECW. He got involved in a brawl with Taz after the match and a feud evolved between the two, but it was scrapped as 911 left the promotion by early 1996.
911 wrestled in World Championship Wrestling (WCW) in 1996 and 1997, under the names Tombstone, Sledge Hammer, and Big Al.
In 1998, he returned to ECW at UltraClash in Philadelphia, Pennsylvania, chokeslamming Bill Wiles. 911 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.
