McKellar, 34, and Verta, 36, exchanged vows in an ocean-side church at sunset in La Jolla, Calif., in front of 150 guests, including the bride's sister and maid of honor, Crystal McKellar, who played Becky Slater on The Wonder Years.
Also present were actors Dan Lauria and Allie Mills, who portrayed Kevin's (played by Fred Savage) parents on the show.
The bride wore a mermaid-style wedding gown and a tiara by Renee Strauss while the groom wore a tuxedo with tails and white gloves.
"We wanted an intimate, formal event," says McKellar, who walked down the aisle to wedding music composed by Verta and performed by members of the San Diego Symphony.
A reception followed at a private club, where guests enjoyed a sitdown dinner and dancing to a 10-piece band. The newlyweds danced their first dance to an original Sinatra-style love song written by Verta and performed by McKellar's uncle, Kim McKellar.
The couple started dating in 2001 and got engaged last August in Chicago.

and Kiss My Math
. She has also appeared on many other television shows including The West Wing
Verta is an accomplished music composer for film and television. He also came up with the titles and designed the covers for both of McKellar's bestselling books.
