It’s not easy to talk about myself. I’d much rather talk about you! But I want to open the door for you, so you understand what inspires and motivates me. My story begins when I established D. P. Design in April 1984, believing that every homeowner deserves to be treated as a special person with unique needs.

I’m passionate about helping you, using my talents, training, and experience to make the building or remodeling process as enjoyable as possible. Listening and paying attention to details is the key to helping you achieve your goals. I work with qualified Contractors and honest Suppliers to achieve the best results by maintaining clear, reliable communication, and ethical business practices, using the latest technology as a tool. Four words define my professional goals:

Listen. Inform. Create. Delight.

My values:

  • Be loving, compassionate, and understanding with everyone.
  • Respect and admire uniqueness.
  • Share the abundance.
  • Help and serve others to the best of my abilities.


I worked hard to get an education while working full time, to learn as much as possible about interior design and kitchen-bath design. One way that I can prove my dedication to helping you is my commitment to professional standards that include passing rigorous tests to earn certifications, like the ones below.

Early Years:

I have vivid memories of my childhood, going into Downtown Portland with my mother, seeing all of the old buildings graced with columns. But the columns were different! Why?

This question plagued me until my eighth-grade teacher at Kennedy School assigned our class to write a term paper about any subject of personal interest (even a family dog named “Spot”). We were required to thoroughly research our topic. I chose the order of Greek columns: Doric, Ionic, and Corinthian. Preparing the report confirmed my love of architecture.

I had questions about prevalent home styles in Northeast and Southeast Portland with stout tapered columns on large square pedestals that supported the roof over a large porch. They didn’t conform to the Greek Order. Why?

1970s To Present:

My love of architecture flourished when I moved to San Francisco in the 1970s. The architecture was a conglomerate of different styles! A new friend, an architect, recommended buying “Identifying American Architecture” by J. G. Blumenson. Finally, I could name all the distinct architectural styles I’d seen in my life. My spirit soared when I discovered that the homes in Northeast and Southeast Portland were late 19th century Craftsman style, aka the Arts and Crafts style. I learned about the different periods of Victorian architecture, and how American architecture evolved from the first settlers to the present day.

My love of architecture led to getting multiple degrees in interior design. One of my instructors was an avid fan of Frank Lloyd Wright. I fell in love with all of Mr. Wright’s work! It was his Gordon House (originally located in Charbonneau) that brought me back to Oregon from the Bay Area in 2000. My husband, Jay. and I helped to save the home from destruction so a young couple could build their “McMansion” on the site.

The Gordon House was dismantled and moved to its permanent home in the Oregon Garden in Silverton. Two years later, I finished the plans for our award-winning home, “Evergreen“  in Oregon City.  It was inspired by Mr. Wright’s “Usonian” homes (1932-1959) that include the Gordon House. We are so grateful to live in our dream home, located in the oldest incorporated city west of the Mississippi River.

A Lifetime of Creative Interests:

Besides architecture, I love music, and have played the piano since I was 8 years old. Now the proud owner of a Yamaha Clavinova, I love to create gift cd’s with my husband. I love to write, especially if it helps others in any way. My first book, “THE Survival Guide: Home Remodeling won the Pinnacle Award for Best How-to Book the year it was published, and I’m in the process of revising and expanding it to include information about accessible design and sustainability. I’m also writing a book about the magical process of building our dream home. Art, crafts, sewing, gardening, reading, and entertaining are other hobbies that I love. Now you know that I love anything and everything that’s creative!

After reading Simon Sinek’s book, “Start with Why,” I discovered the “why” that’s motivated and inspired me since childhood:

“See the Possibilities. Create a Positive Difference.”
