About the Owner 

Owner of DBS

Bonnie Sundberg

In February of 2012, with the help of her husband Dave as a mentor, she opened the doors to DBS. She is a licensed contractor in both Minnesota and Wisconsin. The best part of owning this business is helping people by repairing their homes, making them more healthy, safe and comfortable. Bonnie strongly believes in creating lasting relationships, with both her employees and customers, and strives for this excellence every day.

Bonnie grew up on a small hobby farm in Duluth, MN. From a young age, Bonnie has held many different job titles throughout her life, the most important one is being a mom. Outside of DBS, Bonnie enjoys spending time with her family, traveling, gardening and outdoor activities.


A world where every family lives in a healthy, safe and comfortable home!


Creating lasting "WOW "relationships with employees and customers, while providing permanent home performance solutions!


Commitment - Integrity - Respect - Teamwork - Opportunity
