The couple invited less than 100 friends and family members to their home over the weekend to celebrate Priscilla's graduation from med school, then they surprised their guests with a different sort of celebration—a wedding!

Mark and Priscilla—who have been together for nine years—exchanged vows in their backyard.

The bride wore Claire Pettibone's Sky Between the Branches gown, which features an illusion neckline and matte sequins.

Post-ceremony, guests enjoyed a family-style meal with foods from the couple's favorite local restaurants, Palo Alto Sol and Fuki Sushi.
