I am married to Sumi Kobayashi (also Princeton '80). We have two children: Andrew (a graduate of Stanford, now working at Amplitude in San Francisco), and Brendan (a graduate of Princeton, now working at Bloomberg in New York).
I enjoy running in the summer and snowboarding in the winter. I have run the Pacific Northwest (now the Seattle Rock'n'Roll) Half Marathon annually since 2006. In 2008, after training on Mauna Kea, Mount Fuji, and Blackcomb and Whistler Mountains, I climbed Mount Mt. Kilimanjaro (19,341 ft.) with my son Andrew.
In 2011, I rafted 225 miles on the Colorado River through the Grand Canyon with my son Brendan.
