The Holbrook High School Class of 1965 is celebrating its 50th anniversary since graduation by hosting the Ten Years of Class, Two Multi-Class Reunion on Saturday, June 13, at the Heward House in Holbrook. “We are making every effort to locate as many people who attended Holbrook High School in the 1960s as we can, and at this point we have already mailed out more than 500 invitation letters to those classmates we’ve been able to locate thus far,” said David Heward, a member of the reunion committee. “But there are still about 500 eligible people whose addresses we haven’t yet been able to find. “That means that if someone has not already received the invitation/reservation form in the mail from us, they need to contact us with their address information.” Contact Heward by phone at (480) 310-6355 or by email at horseheadcrossing@gmail.com.
