Hundreds paid tribute at the celebration that kicked off with a concert and a reunion with those who worked for and with Reagan.
"He did a tremendous amount for this nation and I wish we still had President Reagan in office because we need him today," said Shara Castle, who worked in the Reagan administration.
Held at the Air Force One Pavilion at the Ronald Reagan Presidential Library and Museum, "A Concert for America - A Tribute to Ronald Reagan" honored the life and legacy of the nation's 40th president.
From live testimony and video tributes to a musical salute, the night centered on a man known as a great communicator who changed the trajectory of the U.S.
Saturday's tribute was only the beginning.
An extensive celebration was planned for Sunday on what Gov. Jerry Brown has declared "Ronald Reagan Centennial Day" in California.
