Bo Hanna knows emergencies. The first aid and CPR instructor started teaching as a member of the United States Air Force, then joined Boeing as a firefighter. There, he led the department's emergency medical technician recertification training program before joining Cascade Training Center in Seattle.

Even after all these years, it still interests Hanna that students think they won't know what to do in an emergency. He observed, "Students are often surprised that just a little knowledge can make such a grand difference in the outcome of an event."
