"Catherine is amazing. Her creativity and attention to detail made an unusually daunting and stressful renovation of our entire building a positive and meaningful experience. Catherine was by our side every step of the way from start to finish. She consistently delivered bespoke design concepts that have enhanced the quality of our everyday lives through thoughtful and creative design solutions. Aside from anticipating any issues that could arise well in advance, Catherine was always accessible, professional, patient, and an absolute pleasure to work with. Now that we are back in our house, it is very obvious that her design has improved our daily life in a meaningful way as well as significantly increased the value of our property. Catherine is the real deal and delivers the whole package. I would recommend her without reservation and would work with her on any future efforts!” - Carroll Gardens Town House
"Catherine is an incredibly talented and extremely well-trained architect who delivered our vision of a modern, minimalist aesthetic with excellent finishes. Specifically, we benefited from her attention to detailing and finishes and the use of clean lines to create a space that is very modern while also being welcoming, warm, and airy. She also worked amazingly well with our contractors and successfully managed the construction management phase. Very importantly, she was instrumental in helping deliver the project on time and on budget. Things went so smoothly during the construction phase that we went on to recommend the team for numerous projects within our own building. A home is personal, and a first home such as ours has perhaps even more special significance. Catherine was a pleasure to work with on a personal level.” - Boerum Hill Apartment
