Cottingham Insurance

In February of 1990, Diane Cottingham took it upon herself to start a business that provides personal, one-on-one help with one of the most important decisions of some people’s lives, finding an insurance policy that fits their individual needs. Cottingham Insurance Agency quickly grew by gaining a reputation for client satisfaction and a devotion to making transitional moves as easy as possible. Now a fully staffed agency with offices located in Bismarck and Underwood, Cottingham Insurance remains family owned and is dedicated to finding clients the right policy for their specific needs.”
