Insurance is an ever-changing market, and we know that it is not always an easy thing to understand. Heather’s goal is to educate her clients on not only about the changes in the industry, but she also listens to her clients to understand their needs and advise them on what options may be the best for their individual situation. Heather works very hard to ensure that when clients leave her office, they are in a better place than when they walked in. Customer service is very important to Heather, and she strives to make sure clients are taken care of in a friendly professional way.
Heather grew up on a farm/ranch in NW South Dakota and understands the values of hard work and dedication. She has lived in Bismarck since 1998 when she relocated there to attend College. After getting her degree in Speech Communication she worked in the Banking/Finance industry for over 15 years before making the switch to insurance. It is Bismarck where she raised her three daughters and built a home with her husband Mark.
Heather enjoys a number of hobbies including gardening, canning, hunting, and camping. She also enjoys spending time with her family and making memories every chance she gets.
