Tucson-based Portable Practical Educational Preparation, more commonly known as PPEP, will celebrate its 40th anniversary Friday.
The all-day event at the Tucson Convention Center, 260 S. Church Ave., begins at 8 a.m. with the International Microbusiness Expo.
The expo brings together microbusiness owners from the United States and Mexico to network and attend seminars on how to market their products across the border. A microbusiness is commonly defined as having fewer than 10 employees.
Other anniversary events include a silent auction, the naming of the PPEP man and woman of the year and a dinner with entertainment.
PPEP was begun in Nogales in 1967 to provide education to rural children and now offers numerous programs for rural and impoverished families in central and southern Arizona.
Admission at the event requires registration. To register, go to www.ppep.org or call 622-3353.
