Wherever David Haan Groll MBA ’69 was, or whatever he was doing, from golfing to initiating his favorite hand-slap game with Botswana children, his genuine kindness, curiosity about the world, and infectious laugh shone through. Dave kept in touch with everyone and enjoyed surprise visits, traveling the world alongside his wife, Betty. Whether they were on the back of a donkey cart bumping through a Mongolian stream or atop a skyscraper in Basel, they always came packed with PB&J sandwiches. David died Feb. 24, 2022. Betty and their family survive him.
