I have been an orthodontic treatment coordinator and office manager for ten years. I handle all aspects of caring for your orthodontic needs from your first phone call gathering information, to your first orthodontic evaluation and answering all your financial and insurance needs. I want you to feel a part of our orthodontic family! I live in Lake Forest with my husband and two small boys. If I am not busy helping you and your family in the office, I am at the beach paddle boarding with my family or doing some other form of outdoor activity. Let me know how I can help you with your orthodontic adventure!

Welcome, If you are looking for the Greatest Orthodontist ever, you have found her here in Rancho Santa Margarita. My name is Vivien and I have been an orthodontic professional since 1989. I love all aspects of orthodontics. My favorite part is getting to know our patients and helping them throughout treatment until the completion with that "Great Big Happy Smile." Originally from New Jersey, I am the youngest of four older brothers that has helped in learning all sports and crazy antics. Come and join our family and you can finally get that "Great Big Happy Smile" too.
