About Paul Backhaus, Owner and CEO

Allow me to introduce myself, I'm Paul Backhaus, the owner, CEO, and the driving force behind Source Mountain Supply, LLC.

Paul Backhaus, owner of Source Mountain Supply, beside the company sign

Entrepreneurship has been a guiding force in my life since my youth, inspired by my father's business endeavors. His commitment to customer care and dedication to service have profoundly shaped my approach to business.

From the young age of 13, I've been cultivating my entrepreneurial spirit.

In 2012, my wife and I embarked on a remarkable journey when we took ownership of Source Mountain Supply. Our early days were marked by humble beginnings, operating out of our garage while our vehicles braved the elements outside. Fast forward to the present, and our progress has led us to expand our warehouse which is filling up rapidly!

Beyond the confines of business, I am blessed with a devoted wife of 15 years and a wonderful daughter.

Wisconsin has been our cherished home throughout our lives, and we take immense pride in our community and heritage here. I serve as a Lieutenant at our volunteer fire department, indulge my passion for deer hunting, and revel in the joys of being a proud sports dad.

At Source Mountain Supply, we champion the values of service and personability. Our commitment to our customers knows no bounds, and we constantly strive to deliver solutions that exceed expectations. I eagerly anticipate the opportunity to connect with you and explore how Source Mountain Supply can cater to your needs.
