wed her fiancé, Morty Coyle
, in a private celebration in Beverly Hills, the former Full House
Make that really
private – last month, the couple celebrated one year of marriage.
"We had wanted to keep it quiet and intimate for a while, but felt that on our first wedding anniversary, it was time to share!" Sweetin tells PEOPLE.
The couple, who got engaged
on the actress's birthday in January 2011, exchanged vows on March 15, 2012. "Our day was a wonderful, intimate celebration with each other and our families," she says.
The wedding was officiated by Coyle's All Day Sucker
bandmate and longtime songwriting partner Jordan Summers, and the ceremony was held at Summers's home with his wife, Tia. (Click through for three more pictures from photographer Dana Hawley
Sweetin, 31, wore a tea-length Oleg Cassini dress. Her daughter Zoie
(with ex-husband Cody Herpin), now 5, and the newlyweds' daughter Beatrix, now 21⁄2
, participated in the ceremony.
After her surprise engagement, Sweetin told PEOPLE she was "thrilled," and noted that Coyle's proposal was the icing on the cake. "We were absolutely committed before this, anyway," she said. "We're just so excited."
The couple had previously held off on setting a date until everyone could wed, but recently reconsidered.
"We saw that Prop. 8 was going to court to argue its constitutionality (which we knew meant it would be justly repealed) at about the same time that we went to our friends Ryan and Graham LaConnor's beautiful wedding in Palm Springs," adds Coyle.
"Seeing two people whose love was so pure and enriching to all those around them affected us so deeply that we both looked at each other and said, 'It's time.' "
Sweetin, who publicly reunited with her Full House castmates
last year (Coyle deejayed at the event) is in talks for a movie of the week this winter, while Coyle is busy completing his third album with All Day Sucker.
And while the actress looks back fondly on saying "I do," it's clear that marrying Coyle was just an official way to acknowledge her happiness.
As she told PEOPLE in 2011
, "I don't think anything in the world could be better than what I have."
