After four years of highly successful Summer Dinner Lectures, the Dallas Peace Center has expanded their concept to bring three exhilarating speakers to Dallas throughout the summer months. The first speaker, Rita Marie Johnson, founder of the Academy for Peace of Costa Rica, will deliver “A Nation’s Peace Story” on June 4 at FunAsia, 1210 E. Beltline Rd., Richardson. Dinner will be at 6:30 and the lecture at 7:30 p.m. In 2002, Johnson founded the Academy for Peace of Costa Rica (APCR) in 2003 with the aim of citizens passing peaceful skills from generation to generation. Dinner-goers may buy tickets for one dinner lecture, or for the whole series: A table for 10 for the series is $1,500, and tickets for two for the series are $750. Tickets for one dinner lecture are $500 for a table for 10, $200 for a couple and $75 for an individual ticket. To reserve a seat, call 214-823-7793, or go to www.dallaspeacecenter.org.
