Dennis and Rhonda Riley from zen windows st louisDennis & Rhonda

As a lifelong Missouri resident, I have grown to love the people and beauty that Missouri has to offer. My name is Dennis Riley, and along with my wife Rhonda, we are most excited to be a part of the Zen Windows family. The two of us are thrilled to be providing a no-pressure, simple way to buy replacement windows in St. Louis, MO.

Rhonda and I have always been involved in home building and remodeling as a way to earn a second income as well as provide a relaxing distraction from our full-time jobs. Along the way, we discovered a peace that comes from seeing a project completed, as well as the satisfaction of seeing others enjoying the fruits of our labor. For us, happiness is not achieved through material things so much as the whole experience of life and the people we have met, and have yet to meet, along the way. That is where Zen Windows enters the scene.

For some time we looked for a business that would provide both a product and a service. Since neither of us is fond of being on either end of a high-pressure sales routine, we were intrigued by the Zen Windows philosophy of letting the customer decide exactly what they want and then get a window quote in minimal time. Sure, we can help answer any questions the customer may have, but ultimately we put the decision to purchase replacement windows in the hands of the customer.

It is our goal to leave every customer thinking “Why isn’t everything this easy and hassle-free?” With Zen Windows, you can relax… because it really is that easy!
