My husband and I spend most of our free time together as much as possible, whether it is riding motorcycles, getting brunch on a Saturday or going to events. I like cooking, although I rarely have time, and I’m a huge foodie so going out to eat is a favorite pastime.

My area of expertise is workplace, however, I have worked on hospitality, multi-family, higher education, science+tech, and T.I. projects. My passion is the experiential component of design and design itself. I am a team leader whose skills range from running a project from start to finish autonomously to managing teams and project management.

Megan Meek

Architectural Designer
About Megan

Megan is a University of Colorado, Boulder graduate with a Bachelor of Environmental Design degree. She first became intrigued by architecture when her parents built a home when she was only six years old. Megan still remembers the measuring scale and seeing the finish selection process. Megan loves the puzzle aspect of design and figuring out how all the pieces should fit together to make a cohesive design. Her favorite phase of the design process is construction administration when the design comes to fruition and when all the trades work together to bring all of the technical details to life.

She has always had a fascination in the design process of architecture, interior design, and construction as well as a passion for creating spaces that are not only beautiful but also functional, relevant, and reflect the community that the project is located in. She also loves the forever changing industry and the ability to always learn more to design better for people.
