|Born||Marin County, California, U.S.|
|Spouse(s)||Jimmy Fallon (m. 2007)|
Juvonen was born in Marin County, California, and graduated from the University of Southern California with a degree in sociology and cooperative education. After graduating she worked odd jobs. She was employed at a dude ranch in Wyoming, worked as a private flight attendant, and worked for an artist who was trying to eradicate homelessness. Eventually she got her big break as an assistant to Clarence Clemons, a member of Bruce Springsteen's "E Street Band.
Juvonen married comedian Jimmy Fallon, host of The Tonight Show, on December 22, 2007. After meeting on the set of Fever Pitch, Nancy and Jimmy began dating in May 2007 after Drew Barrymore invited Fallon to a birthday party she threw for Nancy. A few months later, Fallon proposed on the dock at sunset with a Neil Lane designed engagement ring in August 2007 at Nancy's family home in Wolfeboro on Lake Winnipesaukee in New Hampshire. They were married four months later. They have two daughters: Winnie Rose, born in 2013, and Frances Cole, born in 2014; both were born via gestational surrogacy.
Juvonen, who is of Finnish descent, is the daughter of aviation industry executive William H. Juvonen, who is a Stanford University alumnus and former Marine Aviator. In September 1961 while flying a gunnery mission as a new aviator undergoing fleet replacement pilot training in VMF 334, he experienced a wing failure at the fold joint and ejected from his F-8C Crusader jet. To commemorate the event, on March 31, 2015, his son-in-law, Jimmy Fallon, presented him with a commemorative Martin-Baker watch on The Tonight Show (Martin-Baker made his ejection seat).
