Office Manager

Please accept our sincere gratitude for your interest in obtaining your dental care at our office. My name is Sandy Quintana. As Office Manager, it is my pleasure to welcome you and acquaint you with our office staff. Our primary goal is to help you attain your optimum dental health and appearance.

I was raised in Fountain Valley, California, and obtained my dental office management training at Concorde College. I joined Dr. Gahagan’s office in 2007 after many years experience in an excellent general practice dental office here in Orange County.

My husband and I are kept busy with three children we are very proud of – a freshman in college, a junior in college, and one in a graduate master’s degree program and recently married this past November. I’ve enjoyed many years volunteering at High School sporting events with them. Leisure time now includes walking my dog, dancing, reading and scrap booking, as well as vacation trips with my husband to Canada, New York, Cancun and other parts of Mexico.

I am here to assist you with your dental treatment, and I will be pleased to answer, or find the answer to, any of your questions.
