**★★★★★ — mshick16, Nov. 2020**

> Gwen is amazing!  We moved into a new build and I was overwhelmed by all the decisions that had to be made.  Gwen is easy to work with and she was very patient with me, guiding me through different design and color options without making my head spin!  While going through fabrics, she introduced me to one that is normally out of my comfort zone.  I decided to use it on some chairs, and they are now two of my favorite chairs!
> Gwen has such a good eye for both the big picture and the small details.  She was very creative with our spaces and worked tirelessly to be sure we were satisfied.  We absolutely love everything she created for us, and I would highly recommend her.
> Meg S.

**★★★★★ — karencakebread, Nov. 2020**

> I met Gwen when she hosted a Napa Valley Grapegrowers STOMP committee meeting at her stunning home. I knew the moment I walked through the door that she would be the perfect person to guide me through an interior refresh of my home. I appreciate her approach and willingness to blend new ideas with existing pieces I preferred to keep. Gwen’s artistic sense, design expertise and warm personality made this project an enjoyable process. My home feels complete for the first time since moving in several years ago. She and Stefanie are a great team. I would highly recommend Gwen Callan Design!

**★★★★★ — Stuart Grinstain, Nov. 2020**

> I have had the pleasure of working with Gwen on several projects over the past few years. As an architect I appreciate her collaborative spirit. She has contributed significant input to our projects, and her insights into many aspects of the design have made the buildings much better. In addition to her creativity, Gwen is committed to delivering accurate and timely technical information required to keep a project on schedule. It is these design and project delivery attributes that make Gwen such an asset to any project.

**★★★★★ — ckapjian, Oct. 2020**

> Gwen helped us do a major redesign on our house in Yountville. She really helped turn our house into a home.
>
> My wife and I have an art business which we run from our home so it was very important for us to have both work and living spaces. And we wanted a very eco-friendly home. From the very beginning Gwen understood our needs and our aesthetic. Her approach was thoughtful and open, enthusiastic and supportive.
>
> Gwen worked with our contractor to minimize structural changes needed for the remodel.  Walls were opened up, a gas line moved, a shower with walls of glass was installed…lots of thoughtful and creative changes that we absolutely never would have thought of on our own. Our elevated fireplace now has these really cool stainless steel bands that go up our fourteen foot ceiling. It’s all Gwen.
>
>  She used her years of experience and numerous connections to find eco-friendly materials as well as amazing deals on some mid-century pieces that set the tone for our colors and other pieces of furniture.
>
> Gwen understood that we wanted an open restful space to live and to work. She delivered beautifully. Gwen's touches are everywhere and we feel so lucky to have found her.
