The Allendale Cultural Center has expanded its arts program to include classes for young adults.Director Leah Martin announced Monday that beginning in September，three new classes will be offered to the Allendale community.The course titles will be Yoga(瑜伽) for Teenagers；Hip Hop Dance：Learning the Latest Moves；and Creative_Journaling_for_Teens：Discovering_the_Writer_Within.The latter course will not be held at the Allendale Cultural Center but instead will meet at the Allendale Public Library.

Staff member Tricia Cousins will teach the yoga and hip hop classes.Ms.Cousins is a skilled choreographer (舞蹈指导) as well as an experienced dance educator.She is a Master of Arts in dance education from Teachers College，Columbia University.The journaling class will be taught by Betsy Milford.Ms.Milford is the head librarian at the Allendale Public Library as well as a columnist(专栏作家) for the professional journal Library Focus.

The courses are part of the Allendale Cultural Center’s Project Teen，which was organized by Leah Martin，Director of the Cultural Center.According to Martin，this project is a direct result of her efforts to make the center a more necessary part of the Allendale community.Over the last several years，the number of people who have visited the cultural center for classes or events has steadily declined.Project Teen is primarily funded by the McGee Arts Foundation，an organization devoted to bringing arts programs to young adults.The other members of Project Teen are two students at Allendale’s Brookdale High School and three adults with backgrounds in education and the arts.

The creative journaling class will be cosponsored by Brookdale High School，and students who complete the class will be given the opportunity to publish one of their journal works in Pulse，Brookdale’s student literary magazine.Students who complete the hip hop class will be qualified to participate in the Allendale Review，an annual concert sponsored by the cultural center that features local actors，musicians，and dancers.

All classes are scheduled to begin immediately after school，and transportation will be available from Brookdale High School to the Allendale Cultural Center and the Allendale Public Library.For more information about Project Teen，contact the cultural center’s programming office at 988­0099 or drop by the office after June 1 to pick up a fall course catalog.The office is located on the third floor of the Allendale Town Hall.
