I worked with Kristyn for multiple "Designer for the Day" sessions as she helped me renovate my 7,000-square-foot childhood home in Florida after my dad suffered a stroke and needed modifications to make the home fit his new reality. Despite never seeing the house in person, Kristyn transformed it into a space that is not only beautiful, but also functional, comfortable, and perfectly suited to my dad's needs. My only "complaint" is that every single thing she selected was so beautiful that making decisions became almost impossible - I was constantly choosing between things I absolutely loved vs. couldn't live without. And that's saying a lot because I'm incredibly picky. Beyond incredible design talent, what really sets Kristyn and her team apart is how much they genuinely care. They operate like a family and treat your home with the same thoughtfulness, attention, and respect they would give their own. Working with them felt deeply personal, collaborative, and completely stress-free. I can't recommend Mark Design Co highly enough. They exceeded every expectation, and I'm counting down the days until our next project together.

We had the absolute pleasure of working with Kristyn. She is kind, professional, and incredibly talented. We hired her for the “Designer for the Day” service, and she helped us select the perfect flooring and paint colors for our home. Her eye for design and attention to detail made the entire process enjoyable and stress-free. We highly recommend Kristyn and her team!

We have loved working with Kristyn and her team on various projects. They helped us fully furnish our Primary home and are now guiding us through a new construction, which has been invaluable. They are incredibly responsive and truly a pleasure to work with. I fully align with their designs and now rely on them heavily for anything design related. Having a team I trust this much makes balancing multiple projects incredibly easy and exciting. I definitely could not do it without them! Kristyn was recommended to me by one of my very best friends, which I am so very grateful for. I highly recommend anyone to work with Kristyn and her team!

We had the absolute pleasure of working closely with Kristyn Mark and her team at Mark Design Co. for over a year on the comprehensive renovation of our 5,000 sf home in Newport Beach. Their incredible professionalism and meticulous attention to detail was truly transformative. Kristyn's remarkable talent shone brightly as she took our vision and turned it into a reality. She was involved in almost every aspect of our whole-home renovation, including expanding our kitchen and adding an entirely new in-law suite. Each space she touched now perfectly marries functionality with beautiful, luxurious, and sophisticated aesthetics — vastly exceeding our expectations. Kristyn seamlessly collaborated with our general contractor and tradespeople. This stellar coordination fostered an environment of trust and facilitated a stress-free renovation process. Kristyn's masterful material selections, from the finest stones to elegant lighting fixtures and luxurious fabrics, demonstrate her refined taste and deep appreciation for detail. She further impressed us with her knack for coordinating custom furniture design, adding a truly unique touch to our home. Trust is paramount when it comes to turning a house into a home, and Kristyn has undoubtedly earned ours. Her unwavering dedication and passion were infused into every aspect of our project, ultimately turning our house into a dream home perfectly tailored to our tastes and lifestyle. Even as our major renovation phase has concluded and we are now thoroughly enjoying our home — we are thrilled to continue working with Kristyn and Mark Design on additional smaller projects. Their work has forever enhanced our living experience, and we wholeheartedly recommend Kristyn Mark and her team for any interior design project. With Mark Design, you're not just hiring a design team; you're investing in a trusted partner who will lead you on a transformative journey to a home that is a true reflection of you.

It has been a joy working with Kristyn over the last few months. She helped me and my husband renovate and furnish our home. In the months that we worked with her, Kristyn was always very professional, responsible, and easy to work with. I also loved her design ideas and furnishing choices that she presented. She was also very good about sticking to the budget that we set for her. And the finished product? So much better than we expected. So beautiful and dreamy! I would definitely hire her again for another project, and would highly recommend her if you are looking for an excellent interior designer.
