Former Sonoma resident Alexandra Lawrence, now a specialized private tour guide in Florence, Italy, and a university instructor at several American and British universities, will return to Sonoma on Aug. 16 for a lecture at Vintage House senior center.

A graduate from Sonoma Valley High School and currently living in Florence with her husband and 8-year-old son, Lawrence often leads tours of Sonoma’s Sister City, Greve in Chianti, which is approximately 20 miles south of Florence.
