The actor might be most readily recognized now for his recurring role on "Criminal Minds," and he also played a menacing character on several episodes of "Private Practice." Brendon, who began acting to overcome his stutter and served as the first-ever honorary chairperson of the National Stuttering Foundation, entered rehab for alcoholism in 2004 and again in 2010, after he took a swing at a cop. He and his wife, Tressa DiFiglia, divorced in 2007.
In 2010, Brendon debuted an online comic, "Very Bad Koalas." He's pictured at left a New York City Comic Con event with fellow "Buffy" vet Clare Kramer, who played the Season 5 villain Glory.
