The weeklong seminars will be offered to young adults throughout the country in the upcoming 2013 year. The first of the programs, which will take place in Los Angeles in March, will focus on Jewishness and comedy. The creative writing program will take place in Amherst in June, and the final seminar, which will focus on theater, will be held in New York City in August.
