Surrounded by family, friends and fellow Bachelor and Bachelorette alumni like Ali Fedotowsky, Emily Maynard, and Jason and Molly Mesnick, the couple said "I do" in an outdoor ceremony officiated by franchise host Chris Harrison.
"Today is all about our friends and family," Hebert, whose nuptials will air Dec. 16 on a two-hour special on ABC, tells PEOPLE. "It's about standing with J.P., looking around at all the people we love in the same room there to celebrate our love."
The 28-year-old dentist from Madawaska, Maine, met New York construction manager Rosenbaum, 35, on season 7 of The Bachelorette. The couple became engaged on the season finale.
Hebert and Rosenbaum are the second couple in the franchise's 24 seasons to make it from their show finale to the altar, following in the footsteps of Bachelorette Trista Rehn, who married Vail, Colo., firefighter Ryan Sutter in 2003.
