Kind Words ...

"Jamie has a great eye for design while catering to your personal taste! We hired her to design the layout of and source all the furniture and decor for our office/photo studio space in downtown LA. The main function of out studio is for shooting product and content for an apparel brand, but we still wanted it to look very lifestyle and natural. Jamie really nailed the feel and aesthetic we were going for - her presentations and communication with us were straightforward and concise yet personable and warm. Jamie made the whole process so easy for us - she gave us great options to look at without overwhelming us and walked us through everything clearly. She was our first time working with a professional interior designer and she definitely set the bar high for us." -Elise M.

"Jamie was amazing. First she helped us figure out what our design style was. Secondly, she worked with us to produce a flawless, elegant design. She suggested wonderful materials and fixtures and found alternates for us when we asked for them. She was mindful of our budget and our priorities. Finally, she saw the entire project through to completion, keeping the vendors on track and adjusting the design on the fly as construction realities dictated. She even assisted us after the project had been completed for months to remedy an issue caused by one of the vendors. We would highly recommend her."

-Cate & Saul W.
