Our Process

  • “Angela was a pleasure to work with throughout the whole process of relocating my practice. She guided me through the space planning phase, drew up the construction plans, and procured all the products. Her ability to know which colors, finishes, and designs work together is truly a gift. She worked seamlessly with my contractor and was very aware of the budget we had set. I confidently recommend using Angela for any project you may have.”

    — Dr. Todd Hartwig, DC, Owner - Marcum Chiropractic, Portland, OR

  • "Angela has a gift for truly interpreting a client’s ideas and transforming them into reality. She is extremely knowledgeable and experienced. Her clients’ concerns are Angela’s priority, and this provided invaluable peace of mind from the beginning of the project through completion. I welcome the opportunity to work with Angela again.”

  • “I had great experiences working with Angela, when she designed several commercial offices and retail projects that we built in the Pearl District. I would highly recommend her to clients. She’s very fun to work with and professional, provides thorough construction documents, and has great design ideas!”

    Jason Chupp, VP Swinerton Builders, Portland (previously with Howard S. Wright Construction)

  • “Angela designed a law office for us. We have lived in the space now for almost five years. Rarely have I hired someone to do a project which turned out as well as Angela’s design has for us. I recommend her for any design project she is seeking to do, as she was a great listener and gave us a thoughtful design that perfectly suited us then, and has grown with our needs.”

    — Dennis Black, Managing Partner - Black, Chapman, Webber, & Stevens Law, Medford, OR

  • “Angela took our ideas and early sketches for our new home and led us through the entire design, permitting, bidding, and construction process. She took the time to understand and deliver on our vision while ensuring that our dream home could be constructed in a cost-effective manner. She brought ideas and concepts we would not have imagined on our own. She was extremely responsive and worked well with our builder and others involved in the final package. We strongly encourage anyone looking for a full-service designer to contact Angela.”

    Dale Muellerleile, Homeowner – Mt Vernon, WA

  • “Angela designed my historic home from top to bottom, and 12 years later I still appreciate her work. She created a fabulous design and kept within our budget. When we bought a second home, we hired Angela again. I recommend Angela without reservation.”
