Influenced by the California lifestyle, Terri Brien Interiors focuses on creating comforting and curated spaces through the blending of new, timeless vintage and hand-crafted elements.

We are a full-service boutique interior design firm based in Southern California. We offer services ranging from virtual design, furniture and styling, light commercial to remodels and full service ground up packages. Our overall aesthetic can best be described as Pacific modern organic, blending contemporary elements with found objects and artisanal pieces. Through infusing our designs with one-of-a-kind locally handcrafted pieces, and layering in texture, we create spaces that combine warmth and elevated comfort. 

There are so many decisions to be made and numerous details that can make all the difference in the way you live, and we are here to alleviate that decision making process. Through our project management system, we remove the uncertainty and stress of selecting, procuring and managing all phases of the design process. By gaining insight into how you and your family live in your home we seek to incorporate elements that are not only beautiful but will enhance and elevate your daily lives.


Terri has expertise in her more than 20 years of high-end residential design and is undyingly passionate about building beautiful spaces. 

While studying design Terri began her career in the design studio of a highly distinguished residential builder in Southern California. From Design Assistant to leading a team of designers throughout Southern California, Terri and her then design partner, received the 2014 Building Industry of Southern California award as Design Team of the year.

Terri, her husband Will and French Bulldog Mugsy, reside in South Orange County. She draws inspiration from Southern California infusing it with her passion for unique, one-of-a-kind type finds. Terri believes that bringing in elements of timeless, vintage pieces is essential for creating depth and character to a space worth living. Albeit Modern or otherwise, leave it to these special pieces that Terri seeks out to achieve a well-traveled and beautifully curated space. In her spare time, Terri can be found trying out new recipes, new restaurants or hitting an antique fair. One of her, Will and Mugsy’s favorite things to do is hit the beach trail in San Clemente.

“Beautifully designed! Terri listens as a designer. She was able to pick up on what I like and even presented me with options I never would have considered on my own. She was also incredibly timely, communicative, and organized with her presentation. I trusted her and I love the
design she gave me. Elegant and welcoming."

“I can’t say enough kind words about TBI. I asked for a design that would be relaxing but sophisticated, and Terri delivered that and more. Every one of my clients has remarked on how wonderful my new spa looks. Whether it’s the furniture, flooring, paint color, wall paper choice or decor items, it all beautifully works together in one cohesive design. I couldn’t have done it without her expertise. I would recommend her design services to anyone because she brings so much knowledge and value. You’ll be happy with the finished product.”

“Terri did an awesome job on our first-floor remodel! After everything was finished we noticed so many personal touches that she had incorporated into the design that we had mentioned during conversations. She incorporated art, books and photography that reflected our love of the California Desert and even a photo of Catalina Two Harbors where my husband and I had met...We had such a great experience working with Terri and plan to use her on
the next phase of our remodel."
