John Adron Dennis is an American broadcaster best known as the co-host of WEEI-FM sports radio's former Dennis and Callahan morning show. His tenure officially ended on August 18, 2016, following doctors' orders to 'reduce his workload.'
Dennis is a 1974 graduate of Kent State University. At age 22, Dennis served as sports director and weekday anchor for WDAF-TV, an NBC affiliate in Kansas City, Missouri. He later became a studio anchorman at WPSL radio. In 1977, he joined WNAC-TV Channel 7 (later WNEV and now WHDH-TV) in Boston. Over the next 21 years he covered the Boston sports scene for the station holding the following roles: weekend and weekday sports anchor, sports producer, sports director as well as producing several sports features and investigative reports. Dennis is involved with several Boston based charities, raising money for the Jimmy Fund, the Cystic Fibrosis Foundation and he is on the board of directors for the Mutual Funds Against Cancer Organization. Dennis has made cameos in many of the Farrelly brothers' films. In April 2015, Dennis entered an inpatient rehab facility to receive treatment for alcohol abuse. On August 18, 2016 Entercom announced that Dennis, under a doctor's advice to reduce his workload, would immediately leave the morning show but would still be at the station for fill ins, relations with advertisers, and special events.
In 1999, the Boston Globe's executive sports editor, Don Skwar, banned its sportswriters from the Globe from appearing on the Dennis & Callahan morning show because of its perceived lowbrow humor. This came two weeks after he banned Globe sportswriters from appearing on WEEI's afternoon The Big Show after columnist Ron Borges appeared on the show and used a racial slur to describe New York Yankees pitcher Hideki Irabu. After the ban, WEEI retaliated by banning Globe sportswriters from all WEEI programs.
