After graduating, he worked for more than 38 years at W.L. Gore & Associates, where he devoted his gifted expertise to delivering computing services and solving problems demanding patience and creativity.

John spent much of his youth in Switzerland, was an expert skier, and loved the mountains. He met Denise, the love of his life, while skiing in Vermont. They shared a strong marriage that strength-ened and fulfilled him.

In addition to skiing, John had many other interests, including a love for theater that he nurtured by producing Brandywiners shows at Longwood Gardens in Kennett Square, Pa. He loved trips with friends, the purple martin community in his garden, pets, and the peaceful grace of his homestead.
