Testimonials

We couldn’t be happier with our experience working with Katie and her wonderful staff at Katherine Mueller Design.

Moving into our new empty nester home in Scottsdale was a fresh start for us, and Katie and her team made the entire process seamless and exciting. Especially for someone who feels overwhelmed with these types of permanent decisions. They took the time to understand our vision — creating spaces that feel both sophisticated and welcoming — and brought it to life with incredible attention to detail. Every piece feels thoughtfully chosen, and the whole home is fresh, beautiful, and truly ours. This design team made what could have been an overwhelming process not only easy but genuinely enjoyable. We are so grateful for their creativity, professionalism, and personal touch!

After living in our townhome for a couple winters I decided it needed some major updates.

I set up appointments with two different interior designers. The first appointment was with Katherine Mueller. Katherine arrived at my home and she and I spent about an hour together. She listened to needs, my ideas and my concerns. We walked around my home and Katherine got a real feel for what was needing to be done. She came up with reasonable ideas where I thought none were available. She walked me through what her process would be and what the contractor’s process would entail. Part of my concern was having the renovations take place while I was out of state. Katherine assured me that that process runs smoothly.She told me that if I choose to work with her design firm, I would be working with her and also one of her design consultants. As we talked further about the whole project, I could tell Katherine was really listening to me. She knew exactly what I was wanting and needing.

Katherine left my home and I had a really good feeling. I promptly cancelled the appointment with the second designer. I called Katherine’s office and told them I wanted to work with her firm. Katherine and Christa (Interior Designer & 3-D Modeling Specialist) couldn’t have been easier to work with. From the zoom calls, to the selection process, everything was so easy. They were in constant contact with me. Christa understood the scope of the project and offered a number of ideas. Christa worked closely with the project manager and kept me updated on everything.

I have to say this was one of the most rewarding projects I have ever been involved with. My husband and I have built a few homes and done some renovating. Working with Katherine Mueller Design was such a pleasure. The project turned out beautifully. Katherine and Christa were amazing to work with. I would highly recommend Katherine Mueller Design to anyone.

My husband and I were building a new home in Albuquerque, New Mexico and looking for a designer that could give us something extraordinary. After seeing the beautiful work Katie & her team did with our friend’s home in Scottsdale, we knew they were the right design team for our project!

A new build project involves an enormous amount of decisions, from flooring, tile, countertops to lighting and more. KMD was with us throughout to navigate the process seamlessly.

Being in a different state was never a problem, as we were in constant communication. And they were always available to answer those immediate questions.

We knew we wanted a modern farmhouse design with high end finishes, but comfortable and welcoming. Katie and her team created a functional design that met all of our needs.

We were so impressed with their knowledge and resources for providing custom built furniture, one of a kind accessories and unique statement pieces. All the things we were looking for to make our home exceptional. Each room flows with purpose and there’s something in every space that catches your attention.

With their keen eye for blending old and new, they were able to bring our vision to reality and we couldn’t be more pleased with the end result.

We can’t say enough good things about Katie Mueller and the Katherine Mueller Design team!

Thank you Katie, for making our dream home a reality!!

Katie and team picked out some of the most beautiful tile I would have never picked out myself – and I loved it.

Also let me highlight to you her space planning is worth its weight in gold alone. She understands the requirements necessary for things to FUNCTION in high traffic area. Trust her. Definitely will work with her in the future, she took a massive amount of headache for our remodel off my hands, thank you Katherine!

Working with Katherine Mueller Design was one of the best decisions we ever made.

We recently embarked on a major remodel of our home and yard, and without their knowledge and expertise, our final vision wouldn’t have been possible.We had some very specific and intricate design requests, such as a marble and steel inlay in our entrance flooring and high-touch details like custom wall molding and wallpaper. Not only were they able to execute these complex ideas flawlessly, but they also made innovative suggestions that enhanced our vision beyond what we had imagined. Katherine Mueller Design nailed everything—from the tile and stonework to the furniture layout. Their patience, professionalism, and extensive knowledge made the entire process enjoyable, and we couldn’t be happier with the results.

Talented, Trustworthy and Resourceful Design Firm

When looking for a designer to help us remodel a 1996-era home to be our long-term retirement property, we’d interviewed several other design companies but weren’t finding someone with whom we felt a good fit. Then, we happened upon Katherine Mueller Designs. We contacted Katie and from the initial phone call, we felt like we were working with a trusted friend.

We appreciated her process and approach. We knew we wanted to be hands-on in the process, which some other designers were not as comfortable with. Katie and her team were wonderful to work with, wanting to first understand the outcome we wanted, then being very collaborative in taking our feedback and finding ways to incorporate them into a beautiful overall design to achieve that outcome. While being very open to our ideas, they were not afraid to educate us on why an idea might not be the best option based on our goals and desired outcome, guiding us in a better direction. Seeing some of her turnkey projects for hands-off clients, I’d highly recommend Katie whether you want to be involved with the project or whether you’d rather be completely hands off.

During the design phase, Katie and her team were available face-to-face, over the phone and via email/text, creating and evolving the design, offering resourceful and creative ideas, presenting fun and interesting materials and finishes, driving the process forward while providing updates at each step of the way. Once the design documentation was complete & materials selection documented, Katie and her team joined us meeting with potential contractors to translate the project scope and design vision for them (hugely beneficially in helping the contractors accurately bid the project).

As we reviewed contractor’s bids, the KMD team was incredibly helpful providing guidance for us making decisions on where to spend money to really make an impact, and where we could save money to maximize the bang for our remodeling buck.

Once we’d selected the contractors, the actual construction phase lasted 6 months and without the attention to detail and thoroughness of Katie’s planning, it likely would have lasted much longer. Having Katie and team on site at critical points working directly with the craftsmen was invaluable in ensuring that the design translated from paper to reality efficiently and effectively. As walls were opened and surprises uncovered, Katie found creative and workable solutions to solve for the inevitable unforeseen challenges that arose during construction. The detail of her design and documentation, however, really cut down a lot of potential issues before they arose, or worse created rework.

We love the outcome and enjoyed the process. We would be thrilled to work with Katie and her team on future projects and thank them so much for making what can be a big, disruptive remodeling process extremely manageable and dare we say, even fun!

We recently had the opportunity to work with Katherine Mueller Design for the first time and it was a fantastic experience from start to finish.

I would highly recommend Katherine, as well as her entire team, for any interior design needs. The project we worked on together was a major home renovation and their communication, attention to detail, and decisiveness all ensued the project went exceptionally smooth and turned over a fantastic end result. Would highly recommend!

Words cannot express how happy we are with Katie and the Katherine Mueller Design team!

Our house went from a moody, dark, faux-painted Tuscan style to a light, airy Transitional space that is perfect for entertaining. The artisans that Katie referred us to were perfectionists in their crafts and we absolutely love the finished design! Her support team was outstanding! Always keeping us informed on supply chain, installation and deliveries -they were a joy to work with. Thanks KMD- we love our “new” home!

It was a joy to work with Katie and her entire team.

My wife and I had been looking at properties in Arizona for over a year when our realtor showed us what became our home. It was new construction and exactly what we were looking for. As we pondered how to furnish it, our builder recommended Katherine Mueller Design as she was the designer he used on the home. We could not have been happier! Not only did Katie listen to our wishes and concerns, but she guided us through formidable decisions. She was responsive and available when we had questions, and helped us with the design choices. She also suggested little touches that were perfect for us! She helped us with everything from furniture and artwork to bedding and linens to dishes and accessories. Her team was wonderful to work with, especially since we were from out of town. They were interested in making sure we were pleased with the outcome, worked around our schedule as best they could and exceeded our expectations! Katherine Mueller Design made an overwhelming project come together easily and beautifully!

Katherine Mueller Design provided us with a highly skilled team of design.

You’ve probably heard the saying, ‘You don’t know what you don’t know.’ This couldn’t be more true, especially when it comes to our experience with Katherine Mueller Design. At first, we questioned why we needed a designer for a seemingly straightforward remodeling project. What could Katie and her team really bring to the table? What was the real value? I’ll admit I was a bit skeptical at first. Looking back, though, I realize I was in for quite an education.

What we received was invaluable. Katherine Mueller Design provided us with a highly skilled team of design, product, and logistics professionals who shepherded our $500K remodel from start to finish. This included comprehensive design services with detailed, to-scale drawings for all vendors, suppliers, contractors, and subcontractors. They offered unlimited design, decor, furniture, and supplementary selections, complete with detailed product specifications for each room. They also managed everything from ordering to delivery (and storage) to inspection.
Peak One, our prime contractor, regularly sought their advice and guidance.

Any deviations from the plan or specifications were swiftly addressed and resolved. But what truly stood out was the care and dedication of the team. Their passion for their work was evident in every interaction and communication throughout the project. This care is what truly solidified our relationship with them, and it drove their focus, communication, and ultimately, the successful delivery of our project.

We didn’t know… but we sure are glad we know now!

Katie has an exceptional eye for design and a natural instinct of creativity.

It was our first time working with her and we picked the best, she listened to what are needs were and set out on a journey to make it work!
Our home was a complex endeavor that she tackled and was always ahead of the game. She has many connections and resources for just about everything you would need in your home such as customizing furniture, accessories, etc. We strongly recommend her for new builds, remodeling, renovations and more! Once again the most attribute we liked about her is her willingness to please and that she took the time to get to know your likes and dislikes, once she gets that, she’s off and running to help achieve your goals!
She also has a wonderful staff to help accommodate your needs also!

Katie did an excellent job of balancing vision, cost, practicality, and buildability.

We were referred to Katherine Mueller Design by several friends who had previously worked with her on their remodeling and new home construction projects. We first worked with Katie on a small project. We were really impressed at how those small changes created a fresh look for that part of our home.

As we planned on spending significantly more time in Arizona, we considered how we might transform what we bought in 2006 as a vacation house, into our permanent home. We asked Katie to consult with us, walking through the house, envisioning what ideas she might have to both update and transform our home. She challenged us to consider significant changes, which we never would have envisioned or considered on our own … while incorporating her previous project, with us, into the new vision. We walked away from that session excited and inspired to begin a complete remodeling project. Katie worked extremely closely with the builder, as both the creative design lead, but also as our representative (“feet on the ground”) while the work was done over the summer of 2022.

In these roles, Katie did an excellent job of balancing vision, cost, practicality, and buildability. So much so, that the builder referred Katie to other clients of his because of how great she was to work with from his perspective. The transformation is now complete, and we couldn’t be happier. We’d recommend Katherine Mueller Design for projects big and small. We believe her greatest value is that she’s capable of bold visions balanced by practical execution.
