Welcome to David C. Duncan Insurance Services! We're an independent insurance agency located in Rancho Santa Margarita, California. We offer a variety of insurance products to individuals, families, and small businesses throughout Orange County. We represent a carefully selected group of financially sound, reputable insurance companies. But remember, we work for you, not the insurance company.

FacebookIf personalized service and excellent rates are what you're after, then look no further. You can count on our expertise and friendly advise to provide you with the personalized service you’d come to expect from a small agency with the insurance products of a large national brokerage firm. No longer will your calls be answered by an automated attendant or deal with a customer service representative who doesn't know who you are.

At Duncan Insurance Services, you'll receive highly personalized service from the agency owner himself, David Duncan. Your satisfaction is what drives our agency!
