  • "The last year my husband and I have been planning a renovation to our home. Having previously collaborated with her on our home, when it came time to reimagine the space and an addition, there was no question who we wanted Maria-Ximena Coriat- MXC Intl and her team by our side. This project has been a major undertaking for my husband and me — including a kitchen expansion, a new side entrance with a mudroom, and a brand-new garage with a guest apartment above it. From the very beginning, she understood our vision and helped bring our dream addition to life with creativity, organization, and attention to detail. What Could have easily felt overwhelming became much more manageable thanks to the weekly meetings with her and her team. Their communication, guidance, and thoughtful planning kept the project moving smoothly and made us feel supported every step of the way. She has an incredible ability to balance functionality and beauty while truly listening to how we live as a family. We are so grateful for her dedication, professionalism, and talent, and we cannot wait to enjoy these beautiful new spaces for years to come". -2026

  • "Working with Maria-Ximena Coriat, our interior designer, and her team at MXC Intl over the years has been an exceptional experience. We have completed multiple projects together, including the renovation of our principal bedroom and principal bathroom, both of which were transformed into spaces that are as beautiful as they are functional. Her use of materials and space is highly creative and thoughtfully executed. She incorporated colors and design themes that reflect our personal taste, resulting in a tranquil, restful bedroom and a modern, elegant bathroom. In addition to these spaces, she also redesigned our family room and living room. I greatly appreciate her ability to work with existing furnishings and reimagine their placement to maximize both flow and functionality, making our home more comfortable and enjoyable for our large family." -2025

  • "This quote from Immaculée Ilibagiza, Rwandan-American author and motivational speaker states perfectly what Maria-Ximena created for me in my new home: “ You want to have some small space, some sphere that belongs to you only that will not be invaded by anyone else. You want to have some thing that no one sees a place to protect your dignity from offense. You are prepared to guard it and to hide it from all other eyes. You are convinced you have a right to it. This is your intimate possession and you are ready to fight to defend it.” This is what Maria-Ximena has created for me with her choices of style, fabrics, colors, accents, and attention to every last detail in my new home. I can never thank her enough for designing a restful sanctuary for me". - 2025

  • "I had a wonderful experience working with MXC INTL. They completely transformed my home using many of the pieces I already owned, proving that a beautiful redesign doesn’t always require starting from scratch. With their expert eye for color, they selected new paint tones that perfectly complemented my furnishings and artwork. They also reupholstered several existing pieces, giving them new life and creating a fresh, cohesive look throughout my home. The result is absolutely fabulous—my space feels both new and personal, stylish yet comfortable. Maria-Ximena Coriat has incredible taste, attention to detail, and a true understanding of how to make a home reflect its owner. I highly recommend them to anyone looking for a thoughtful and creative redesign!" -2025

  • "I can't say enough great things about MXC INTL with just one week to completely transform my home for a major event, I thought we were asking for the impossible — Maria-Ximena delivered beyond anything I could have imagined. From the moment we spoke, Maria-Ximena understood the vision and brought incredible creativity, professionalism, and energy to the project. What amazed me most was her ability to seamlessly blend our existing pieces with new furnishings, creating a fresh, elegant, and cohesive look throughout the entire house. Every room had a thoughtful touch, and nothing felt rushed or out of place. She even managed to handle window treatments — measured, installed, and styled — all within the tight timeline. The result was absolutely stunning. My guests couldn’t stop complimenting the space. If you're looking for someone who can handle high-pressure deadlines with grace, style, and a sharp eye for design, I wholeheartedly recommend MXC INTL. We are still in awe of the transformation — it truly felt like walking into a new, yet still very "us," version of our home. Thank you for making such a special moment in our lives even more memorable! " - 2025

  • "It was a pleasure working with Maria-Ximena Coriat and her team at MXC Intl. Throughout the project Maria-Ximena spent a great deal of time listening to my vision and then added her own wisdom and skill as a designer to make the final outcome really special. She would often bring me three options, at differing price points, so that I was able to keep to my budget and spend my money wisely. She also served as a general contractor for us as we were often away during the renovation. The result was a flawless remodel, done on time, with great peace of mind on our end. I can't recommend MXC Intl highly enough!" -2015
