Regardless of the style, her work conveys a sophisticated and stylish aesthetic with a fresh interpretation and signature touch of Waltzer’s own.


Here’s what people are saying:


“Kathryn brought professionalism, taste, know-how, and positivity to the job. She ran the remodel and furnishing of my 2500 SF home. We spent a good amount of time discussing the look I was going for.  I never felt like Kathryn imposed her taste on me.  She promptly came up with several floor plans and competently ran the construction phase of the job.  With my consent, Kathryn sourced the subs and directed them where necessary.  When it came time to select finishes and furnishings, she provided lots of choices without overwhelming me.  She stayed on all the providers and vendors to make sure they did their jobs. Any issues were dealt with swiftly and efficiently. I am very happy with the final results, and the process in general.  Kathryn is a pleasure to work with, always very responsive.” – AS


“I hired Kathryn to help me in decorating my home, which was new construction. Kathryn assisted me in identifying and purchasing art, indoor and outdoor furniture, custom fabrics for new dining chairs, outdoor seating and accent pillows, obtaining custom crafted console table as well as identifying and purchasing accessories through out my home.  Kathryn is extremely friendly, professional and  efficient, and she was very responsive to all my needs and requests.  Kathryn is great at listening to her client’s ideas and presenting several options that fit their needs and their budget.  I intend to use Kathryn for all my future design/decorating needs, and I would highly recommend her to anyone.” – AN


“Kathryn recently designed our master bathroom remodel, also helping to choose the contractor, materials and decor items. She has impeccable taste, is extremely well-organized, and is a pleasure to work with on a personal level. She is also efficient and communicates regularly and clearly. My husband and I are thrilled with the result, and credit her with making the project such a resounding success.” – M&T C


“We are almost finished with a 3500 sq. ft. condo project with Kathryn. It is a remodel in which Kathryn played an integral part with the design and the contractor.  We are mostly through the decorating and Kathryn is certainly attuned to the details and has a good working relationship with all the vendors. Through it all, Kathryn has been a reliable, unflappable professional and has demonstrated great skills in working with differing opinions and personalities. I wouldn’t hesitate to work with Kathryn again.” – S&C A


“We moved to a contemporary house after living in a Tudor, and she helped with the move, getting furnishings sold with an estate seller, then figuring out which pieces to keep. She made sure we could plan around much loved furnishings, yet update the entire design to reflect our new contemporary open floor plan. She always kept the big picture in mind, even when planning for the smallest details, like changing the cushion color to our Saarinen dining chairs, which actually warmed up the space and tied together the open areas. She listened to us, and how we wanted to use the space, and made suggestions and choices that reflected this. We love the result, and highly recommend her design services.” – D&D




Influenced by travel, the arts and architecture, Waltzer incorporates the essence of these subjects in each project, whether in metaphor or the form of custom furniture, or creating a color palette, a sensitive updating, a brand new home or commercial space. Equally, influencing a project is the architectural style and the client requirements.  Waltzer’s clients range from bankers, authors, newspaper editors, engineers, graphic artists, film director, surgeons, lawyers, television writers, executives and producers, actors, pro athletes, and a Northern California Winery, Anselmo Vineyards.

Waltzer graduated from the Interior and Environmental Design program at UCLA Extension. She is a Certified Interior Designer, and a professional member of the American Society of Interior Designers. She lives in a Case Study House.
