Hollywood business manager and accountant Gary Haber, whose clients included Carrie Underwood, Peter Frampton, Lynyrd Skynyrd, Julianne Hough, Joe Cocker and screenwriter Les Bohem, died Monday in Los Angeles. He was 68.

Clients David Cook, Kris Allen and Meat Loaf were among those to reach out via Twitter to express condolences.

The Hollywood veteran established his Haber Corporation in 1977 in Encino, Calif., and opened a branch in Nashville as his roster of country artists grew. Together, the offices employ more than 80 people. In 2000, the company expanded again as he teamed with Mark Robertson to open Haber & Robertson International in the Loire Valley outside of Paris.

He was on the board of directors for the Academy of Country Music and the Alliance of Artists Recording Companies. He was actively involved in charitable organizations ACM Lifting Lives (of which he was a past president), MusiCares and the TJ Martell Foundation.

Haber was also the founder and president of the Nashville Screenwriters Conference, as well as part-owner and CFO of Nashville bar and performance venue Music City Tippler.

He is survived by his wife, Sherri; two daughters and two sons; and two grandchildren.

Funeral services are to be held Friday at Mt. Sinai Memorial Parks and Mortuaries in Simi Valley, Calif., at 2 p.m. Donations may be made to ACM Lifting Lives or the TJ Martell Foundation.
