Beyond investing

Hobbies
Outside of work he lists family, travel, exercise, and helping friends start companies among his personal interests.
Family
Buhler is of Greek heritage; his grandfather survived the Nazi destruction of his village in Greece during World War II and later emigrated to the US, working as a shoe-shine kid and in a coffee factory before saving to buy an ice cream cart and eventually opening a diner in Chicago. His other grandfather grew up on a dairy farm in Wisconsin, fought for the USA in the Pacific during WWII, and after the war became a milkman before building a chain of about 90 gas stations across the Midwest. His father was an entrepreneur.
