Richi Caldwell nurtured the broken young men who returned from Vietnam and tried to get their lives back on track at Spokane Falls Community College. She's scolded leather-wearing Hell's Angels. Now, after 40 years of teaching, she's finding more students than ever are suffering from depression. Not yet ready to retire from teaching and helping her students, Caldwell has outlasted several college presidents, countless administrators and many peers. She received a standing ovation during an SFCC luncheon earlier this month for longtime employees. Only one other SFCC staffer has worked at Spokane's community colleges longer."I was the youngest faculty member in '64, by far," said Caldwell, who teaches English, English as a second language and communications.
