Shanahan and Mandy met each other while attending Cherry Creek High School in Denver, Colorado. He was one year his senior.
They started dating only after she graduated from high school.
But their love story isn't without bumps. They broke up soon after because they were attending different colleges but remained close friends.
It took a tragedy to pull them together again. When Mandy's mother Nancy was diagnosed with cancer in 2001, Shanahan took care of her.
In fact, that was when she knew he was the one. "After going through that with him, I couldn't imagine being with anyone else," she admitted to SFGate.

Shanahan had never thought of getting married young. Mandy made him change his plans about that.
The couple got married on July 5, 2005.
Stella became a sister around 2009 as Shanahan and Mandy had their second kid, son Carter.
The coach, who is known for his love of hip hop, might have named him after Lil Wayne, given that his real name is Dwayne Michael Carter Jr.
Then came Lexi, their third and youngest, in around 2013.
Shanahan has made his family move around a lot due to his job. The family now lives in California, where he's busy with the 49ers.
