Here's what I posted on another thread. These guys were all in the Midwest.
DO Sam Herd - Everybody seemed to enjoy his talks, of course that was 25 years ago.
DO Joseph Howard - About 20 years ago, he had a sister on the Ministry School at the Circuit Assembly in tears from the critical harsh 'counsel' he gave. Not well-liked in the district.
DO Joseph Wengert - Grandfatherly figure, seemed nice enough. Never met him personally.
DO Louis Beda - I think they had a cat. Don't remember much else about the guy.
DO Bob Hartman - It seemed like he was in Alaska for a time and talked about how cold is was (-30 degrees) and they STILL went out in service.
DO Steve Konjevich - Seemed nice enough, and I remember he always wanted his lunches at the Kingdom Hall. Made a big deal about people's ethnicity and nationalities.
DO Wallace Goff - Was a MTS instructor, and rarely showed up to circuit assemblies. Pretty personable guy, though.
CO Melvin Branam - Nice guy, always had time for people. Spent time with families and encouraged children. Liked to sit in the back of the Kingdom hall so he could talk to people. Probably my all-time favorite CO.
CO Robert Wickers - Seemed a little full of himself. Not the best speaker.
CO Michael Swanson - Seemed very intelligent. Didn't say much, but he was very perceptive.
CO Stanley Coberly - Former missionary who was sent home from Honduras after getting malaria. Single CO. Nice enough guy, but not much of a speaker. Not the most memorable CO.
CO Arnie Erickson - They were from Minnesota. Still had a motorhome years after the other CO's were forced to give theirs up. Older couple - I think his wife's name was Rusty or something like that.
CO Stephen Miller - Young couple who were very idealistic and zealous. They had a heart and really wanted to help people, as far as I could tell.
After that it gets kind of fuzzy.
