Hank Berger, 27, is a self-proclaimed "disco doctor," and his practice is flourishing. His patients are floundering discotheques. "The failure rate is 90 percent. Only 10 percent know what they are doing," he finds. "You can't make a million from a disco just by putting in some speakers." Berger, a design graduate of Cleveland's Cooper School of Art, began doing graphics for ad agencies, then moved into multimedia production and managing a friend's rock group before creating his own disco, the Club Roundtable, in 1973. In the next five years he owned or consulted on seven Cleveland discos, including two highly successful gay clubs ("Gays are the trend-setters"). Last year Berger sold out his Cleveland interests, enabling his mother, a switchboard operator, to retire, and he moved with his wife, Shelley—whom he met in a disco—to Hollywood Hills. After an article on him appeared in the Los Angeles Times, Berger received more than 500 requests to visit "sick" clubs and analyze what was wrong. His minimum fee to revise decor and sound installation and to change marketing strategy is $2,000. "There's enough work and interest in California," the Disco Doctor figures, "to keep me going for the next 10 years."
