Our Staff

The brief descriptions below are designed to familiarize you with our staff's training, professional credentials and work experience.

  • Dr. Vincent Lim, D.D.S.

    Originally from Baltimore, Maryland, Dr. Vincent Lim moved to California after his dental education. He has always worked hard and tried to become the best that he can be. When time permits, he enjoys life to the fullest by traveling around the world. It allows him to learn about different people and foreign cultures. He loves his profession because it allows him to meet many unique individuals while being able to help them. Perhaps his most memorable accomplishment was when he visited an Indian reservation in Tuba City, Arizona for 3 weeks. There he and his colleagues made dentures for the underprivileged Navajo elderly. Vince always looks forward to engaging in such opportunities to help people. He is married and has two wonderful sons.
