What People Are Saying

The Best

"The best Interior designer in San Diego! I was recommended to have Susan Spath do my house by a friend and I am very happy I did. Everything is so thought out and looks beautiful. I was overwhelmed by moving and she really made the design process and decision making easy."

Top Rated Company

“This is a top rate, full-service company that adds that personal touch in everything they do. They can change an estate in remarkable time with attention to every detail. Susan, the owner, puts her personal flair in everything she does. As an investor who needs to turn a timely profit on high-end residential investments, there is no one else I would use. Everyone I know uses Kern and Co. in my circles. We all know we can count on her to meet our needs with an amazing creative edge, on time and under budget. You won't be disappointed and there is no one else in the industry I would go to!"

Amazing Professional

“I am so pleased with our new home. Susan Spath, of Kern & Co. is an amazing professional as well as a truly talented designer. Although I was living in Brasil at the time, Susan was able to make the most of my trips to California. She kept our home project on track and on budget. We could not have been able to do this without all her help and guidance. I highly recommend a visit to her beautiful store in Solana Beach.”

Fantastic Team

""Fantastic people to work with. The team knows their stuff, have a wide range of selections to choose from. Everyone is warm, friendly and professional. Carol kept up to date, talented and dependable. We refurnished a number of rooms and are now enjoying it all everyday."
