Danielle Koos B.F.A. Interior Design

Managing Director/Interior Designer

Interior designer and owner of Koos Design, LLC. Headquartered in Arlington, VA, I work locally as well as regionally on small to large scale residential and small commercial projects.

Over the past ten years as a designer, I have pursued many creative paths. Student, intern, junior designer, head project manager, traveler, dreamer. All of these endeavors have led me to where I am today, owner and designer at Koos Design.

I've had a vested interest in all things design and sales my entire life. I grew up associating the Eames lounge chair with my grandfather’s study and learning to take my first steps around a Noguchi coffee table, which acted as a balancing piece.

I didn’t realize my passion for interior design until one day I caught myself in the middle of an accounting class building homes on a computer game named The SIM’s. That wasn’t my first time, every day after elementary school I would rush home just to get on the computer to play the game.

If you aren’t familiar with The SIM’s, you build and manage communities and families. Starting with creating the family, buying the lot, building then furnishing the home, and once completed you manage the people. Except I did not care for managing the people, I would find myself focusing on the lot, counting the squares on the screen which replicated the property and creating floorplans on graph paper. I would then build the home, including all of the homes fixtures, finishes, and furnishings.

As the years went on I realized that I had a greater passion for design, helping people, and giving them the resources needed to create their dream spaces. Ever since starting Koos Design in 2018, no other job or career has ever felt right for me.

Assistant Interior Designer

I have always loved design, everything about it! I have been around it as long as I can remember.

My Dad had his own construction company growing up and they did a lot of remodels and new builds. I have photos of my Dad and I laying tile, cutting wood at the age of three! As I got older, I started out just picking up the trash around the job sites. Then I quickly took interest in the projects and the design aspect of them.

My Dad started asking me what I thought about this layout and which countertop I liked more and so many other options. I found myself redoing the whole design sometimes! I guess you can say my love for design started then! I loved it so much I went to school and got my Associates Degreein Interior Design and have been working in the
Design world ever since!

Other than Design I have a few other loves! My family is everything! I have a wonderful Husband, Jordan for the past 11 years we have been together! Our fur baby Kono and we recently welcomed our baby girl Isabella into this world!

Finding out I was pregnant and being a Designer I could not wait to start designing and decorating Isabella’s nursery! I had to do some convincing to the Hubby on my plan but once we finished the nursery he was amazed how it turned out! A good craft beer and Design talk is right up my alley!
