He left Venable in 1993 to form his own small firm, Cacheris & Treanor, but returned in 1997 and retired as a managing partner in 2010. He was the first full-time coordinator of the firm’s pro bono department, which he ran for 12 years.

Berendzen, who pleaded guilty to making obscene telephone calls to a woman in Fairfax County. During the Monica Lewinsky sex scandal investigation, Mr. Treanor represented Nancy Hernreich, who was Oval Office operations director under President Bill Clinton.

Mr. Treanor was a member of the American College of Trial Lawyers and the National Association of Assistant United States Attorneys. His other memberships included the Society of the Friendly Sons of St. Patrick and Holy Trinity Catholic Church in Georgetown.
