Susie Davidson / brookline@wickedlocal.com For Edward Boches, the pandemic was an unlikely catalyst. "I think I kicked into high gear from the lockdown and beyond," he said from his Brookline home near the Allston line. He had been a full-time professor at Boston University for the past 10 years. "I taught creative courses in the advertising program in the College of Communication: Creative Concepts, and Portfolio Development," he explained. "I helped prepare students for careers as creatives — designers, art directors, writers, filmmakers." It was a second career for Boches, who for 33 years was a partner and creative director at Mullen (now Mullen-Lowe), Boston's largest ad agency.
