Jeffrey Hollender, 26, attended four high schools before graduating and dropped out of Hampshire (Mass.) College in his sophomore year. Yet Hollender has found his niche, establishing the Network for Learning, one of the nation's largest noncredit continuing education programs. Since opening its doors in a Greenwich Village loft in 1979, the school has grown to 50,000 students a year—some attending up to four weeks. They pay between $15 and $45 to take such courses as "Around the World on $15 a Day," taught by travel expert Arthur Frommer, and "How to Be a Preppy," by best-selling author Lisa Birnbach. To date Hollender has grossed $1.5 million from his brainchild. The son of a former president of Grey International Advertising and his real estate agent wife, Jeffrey was an entrepreneur even at 15 with a window-washing business in the Long Island Hamptons that grossed $100 a day. After quitting college he founded, in 1976, the Skills Exchange of Toronto. Two years later, with the school drawing 20,000 annually, Hollender turned his attention to New York. The bachelor plans to sell franchises to other U.S. cities and London within the next year. "As far as I'm concerned," he says confidently, "we've only scratched the surface."
