OUR

  • "We highly recommend Triadic Design team."

    We recently just purchased our first home and needed help to remodel our home. With Triadic’s expertise, we were able to transform our outdated home into the dream home we wanted.

    — Teresa & Tudo T.

  • "I could not have done this without the girls."

    Somehow they took all my random words to describe the feeling I wanted to have and brought it to life in my space. Thanks to Cat, Brittany and Priscilla for making it more than I imagined.

    — Jen & Marcus J.

  • "The project was completed and looks just like the design picture."

    This team deserves all the stars you can give. Special note is the professionalism of the Triadic team. Cat, Brittany and Priscilla are great to work with and very attentive to the details. The team recognizes your taste and seem to know in advance what you will like. Attention to detail is outstanding.

    — Deanna & Jack M.

  • "We’ll definitely work with them again in future projects!!"

    The Triadic ladies did a wonderful job helping us remodel our master bathroom. They also helped us find and evaluate several GCs for the project. We appreciate their communication style and ability to work within the constraints of the project. They sourced beautiful materials, and we are happy with the finished product.

    — Caitlin & Daniel K.
