Nearly 200 supporters gathered recently at the University Club of Pasadena to celebrate the 15th anniversary of nonprofit arts center Boston Court Pasadena and honor Greta Johnson Mandell with the fourth annual Z. Clark Branson Award for her advocacy for and support of the arts. The event featured a performance by son jarocho band Los Cambalache and raised a record-breaking amount of money to support Boston Court’s programs in theater, music and visual art.
