McAllister Leaves KNIX: iHeartMedia KNIX/Phoenix morning co-host Matt McAllister and "Producer Joe" Wallace have exited. McAllister joined the station in 2008 from Rock KTYD/Santa Barbara, CA, pairing with Ben Campbell, who continues at KNIX as does the recently added Brooke Hoover (CAT 3/10). "We thank Matt and Joe for their contributions and we wish them the best," says EVP/Programming Steve Geofferies, who is accepting airchecks and resumes for the open posts here.
