Outside the Office

Despite his advancing age, Mark continues to celebrate his status as a 21st century "nerd"—enjoying all the outdoor splendor (hike, bike, Nordic ski) that New England offers while always being down for a game of Catan, listening to podcasts on quantum entanglement or getting lost in books on artificial intelligence. He loves to garden, particularly vegetables, which, upon harvest, he cooks into something yummy. Mark splits his time between a 1830s restored farmhouse he and his artist wife have spent nearly 30 years fixing up and a recently acquired small seasonal cottage on Lake Champlain where summers are spent enjoying the water, family, and friends.
