About Window Depot USA

Our company is an evolution nearly a decade in the making.

In 2011, we started a gutter-guard company that installed Leaf Solution. At the time, Leaf Solution was our only product offering. But we did such a fantastic job that people started asking us to perform other home-improvement projects. We were only too happy to oblige.

Before we knew it, we’d built a base of loyal homeowners who turned to us for ALL of their exterior-remodeling needs. In 2012, we thought, “Why not make it official?” So we formally expanded our business to offer windows, doors, roofing, and siding. That’s when XteriorPRO was born.

Business went from “0 to 60”… fast. We quickly became recognized as one of the top exterior remodelers in the St. Louis metro area because of our meticulous attention to detail and bend-over-backward service.

In 2017, we decided to take our services to the next level. We chose to shed our “lesser” product offerings and kept only the cream of the crop:

We ditched double pane windows and partnered with Window Depot USA to sell their best-in-class triple pane windows. We’re now the official Window Depot USA for the St. Louis Metropolitan market.
We kicked vinyl and wood siding to the curb and now offer only James Hardie fiber cement siding.
We now install only GAF roofing that qualifies for the Golden Pledge Warranty (50 years on materials; 25 years on labor).
In our case, less is more. We may have gotten rid of a few products, but we kept the ones that provide the hands-down best value. As it turns out, homeowners in and around St. Louis and St. Charles Counties—especially the ones who crave the highest quality—prefer our “best or bust” approach because it guarantees they get the most for their money.

We’ve evolved a number of times since launching as an unassuming gutter-guard company in 2011. And the reason we keep evolving? Because homeowners who insist on superior-quality exterior remodeling in the St. Louis metro area demand it.

We’re only too happy to oblige.

Three words that most people would use to describe me would be compassionate, honest, and funny.

My family means everything to me, especially my almost 6-year-old granddaughter who is my favorite person on earth. That little lady makes me laugh and smile constantly. She definitely keeps me on my toes—she is the entertainer in the family for sure!

My other favorite family member is my boy, Niko. He’s a pit bull I rescued 11 years ago. His ‘happy to see me’ dance and slobbery kisses are one of the best things to come home to every day.

Before starting the company, I worked for State Farm Insurance for 6-1/2 years. The knowledge I gained has been very helpful in this industry. I also worked for a large home improvement company as their Marketing Director for just over six years as well.

My belief on how to operate a business: happy customers + happy employees = happy business.

I got my start in the home improvement industry knocking on doors for a large home-improvement company shortly after I turned 16. I didn’t originally intend to forge a career in home improvement. In college, I got a Bachelor of Science degree in Business Administration with an emphasis on Management and Marketing. This might seem like a far cry from home improvement, but it’s an education that has helped me build one of the most trusted window and door replacement companies in the St. Louis metro area. I thrive at working through tough situations and finding resolutions—I am passionate about figuring out solutions to problems that my competitors can’t recognize. Also, I just plain love helping people not only achieve their remodeling goals but doing so beyond their expectations.

Outside of work, I am passionate about…
Reading personal development books and listening to informational podcasts that pertain to business and mindset.
Motorcycle racing. I road raced motorcycles at a professional level, which helped instill a great work ethic and ‘never give up’ attitude that I apply to our business every day.
Golf. I enjoy it because it’s a sport that is very difficult and can never be conquered. There is always room for improvement, which makes it an activity that’s right up my alley.

Product Consultant

I first joined Window Depot in 2016 after working as a carpenter in both the new construction and the remodeling side for more than 15 years. I’ve found that my previous work on the labor side of the field gives me a better understanding of the installation and technical aspects of what we do here at Window Depot, which allows me to be a true consultant to homeowners instead of just another salesman.
When I’m not helping homeowners with their window needs, I’m either spending time with my growing family or running the trails and roads throughout the area.
