Extreme Makeover dentist Dr. Bill Dorfman and former Apprentice contestant Jennifer Murphy were married Friday evening, their reps confirm to PEOPLE.
The couple wed in a non-denominational ceremony at the Trump National Golf Club in Rancho Palos Verdes, Calif., in front of 300 guests, including Esther Williams and several of Murphy's former Apprentice costars.
Murphy wore a gown by Simin Haute Couture and diamond drop earrings from Beverly Hills jeweler XIV Karats, which also designed the couple's wedding bands.
The pair got engaged last Christmas, when Dorfman proposed to Murphy with a 3-carat, radiant-cut diamond ring surrounded by trapezoids.
Dorfman, 47, and Murphy, 27, met at the 2004 Miss USA pageant, when she was Miss Oregon and he was in the audience. But their romance didn't bloom until a year later, when Murphy was cast in an ad for teeth whitening by Dorfman's company, Discus Dental.
On ABC's Extreme Makeover, Dorfman was described as a "cosmetic dentist to the stars." He has three daughters, Anna, Charlotte and Georgia.
According to her personal Web site, Murphy co-founded and serves as president and CEO of a real-estate development company and works as a business and marketing consultant.
The newlyweds are scheduled to leave this weekend for their honeymoon in Fiji.
