Mike Marsilla

I believe that finding the perfect window coverings should be a seamless and affordable experience. My goal is to bring premium quality directly to your home.

My name is Mike Marsilla, and I have spent decades perfecting the art of custom window treatments. Early in my career, I realized the traditional retail model often left customers paying more for lower-quality products and inconsistent service. I knew there had to be a better way, so I built M3 Design Group around one simple idea: provide exceptional craftsmanship, honest pricing, and personalized service by working directly with the customer.

My passion for quality craftsmanship and durable home furnishings has guided every step of that journey. By manufacturing many of our products ourselves, we've eliminated the delays and added costs that come with third-party suppliers, allowing us to deliver premium window treatments at competitive prices. Whether we're working with homeowners, designers, or property managers, our focus remains the same—making the process straightforward, efficient, and tailored to each client's needs.

From the initial consultation and precise measurements to custom manufacturing and professional installation, my team and I manage every stage with care and attention to detail. We know that home renovations and new projects can feel overwhelming, so we're committed to making the experience as smooth as possible. Nothing is more rewarding than seeing a finished space come together, and I'm proud to provide window treatments that our customers can enjoy with confidence for many years to come.

Exceptional Quality and Professional Service

Every property deserves window coverings that offer both aesthetic appeal and long term durability. Our factory direct approach ensures you receive premium materials at a fair price. We take pride in delivering a completely stress free experience from start to finish. Our expert installers handle all the technical details to guarantee a perfect fit. You can trust our team to complete your project on time and on budget.
