Interior Design Intern - Portland Office
Hometown: Portland, Oregon
Courtney’s sensitivity to color and creativity led her to start noticing how different spaces made her feel, which sparked her interest in design. She believes that a good design is founded in purpose, reason, and feeling, and that everyone deserves to experience this. Using her skills from SketchUp, Revit and Illustrator, she is able to create spaces that clients fall in love with. Currently a student at the Oregon State University studying Interior Design with a minor in Business and Entrepreneurship, she’s become the perfect fit for our Portland office! She creates designs that solve problems and spaces that inspire and empower people who encounter them.
Having recently moved back to Portland, Courtney is ready to get back to her roots. You can find her downtown searching for the newest boutiques, at the trendiest coffee shops, or spending time with her family and puppy. Courtney loves traveling and experiencing new cultures, like riding a camel in the middle of the Mexican desert, which she just did recently.
And Ranger, the wonder dog.
Ranger is the new kid on the team and he has very big dog booties to fill! He's in training for the Regional Head of Security position that was previously occupied by the very best good boy, Vern. Ranger hails from Mexico City and has done a lot of traveling in his rather short life so far. He is a guy who takes naps seriously and provides the team with lots of laughs while he's mastering his athletic abilities. He encourages the team to get up and move around throughout the day because he needs potty breaks every 20 minutes or so. He'll be making lots of appearances on our Instagram account, so be sure to follow us @MackenzieCollierInteriors!
