Catalon grew up in the Short Hills section of Millburn, New Jersey and graduated in 1997 from Millburn High School. He attended the S. I. Newhouse School of Public Communications at Syracuse University, graduating in 2001. He served as a sports reporter at WNYT and freelanced at WFAN and SNY in New York City before joining CBS. Catalon served as a tennis play-by-play announcer for the 2016 Olympic Games and has called the Masters Tournament and PGA Championship in golf.
On March 22, 2014, Catalon was announcing an NCAA Tournament game of Gonzaga against Oklahoma State. In order to get back into the game, Oklahoma State was intentionally fouling Gonzaga's Przemek Karnowski, a poor free throw shooter. Catalon called this strategy "hack a polack", to which his broadcasting partner Mike Gminski immediately said "Easy now." Catalon had to apologize on air for his use of a racial slur and to Karnowski personally. Karnowski tweeted that he appreciated the apology.
Catalon lives in New Jersey with his wife, Jessica Layton, who is a news reporter. They have a son, CJ.
