Mackenzie Collier, Owner & Lead Interior Designer 


Mackenzie Collier is the owner of Mackenzie Collier Interiors, where we believe that living in a designed space will dramatically improve your quality of life.  Our designs bring function, quality, and effortless style to our client’s spaces.

Mackenzie graduated with honors from the Interior Design program at Harrington College Of Design in downtown Chicago, IL.  She excelled in a curriculum that combined both theory and practice, delivering a balance of studio, classroom, and independent study.   She was able to explore and learn more about eco-friendly, sustainable interior design at every level of course work.  Through her design education, she developed a well-rounded understanding of the business and creative side of Interior Design.

Before studying Interior Design in Chicago, Mackenzie earned her Bachelor of Science in Psychology from Michigan State University, where she focused on child and family psychology.  Her educational experience enables her to effectively communicate with clients and understand the way in which individuals actually use the spaces in which they reside.   Often design decisions require compromise between multiple clients and Mackenzie is an expert at negotiating so that each party feels their vision has been realized.

Mackenzie constantly searches for new inspiration through travel, art, music and nature.  She believes that your personal style should always be a reflection your own distinct experiences and outlook.  She finds great satisfaction in the process of helping a client define their own style and then molding the elements of that style into an actual physical space.

Mackenzie managed a complete 6 month renovation of the interior and exterior living spaces of our 6,000 square foot home.  She was able to help us define our exact style, create an amazing modern design concept for the project, and then draft drawings to produce really unique and unexpected floor plans, design details and architectural features throughout our home.  We liked being able to see the drawings and approve them or make changes before anything was built.  It gave us peace of mind.  She made detailed architectural drawings to communicate her designs to the contractor and other trades who were working in our home.

In addition to her design skills she was a great project manager.  She defined the budget for each part of the project before we started and then kept an updated spreadsheet of every dollar that was spent to keep us on track.  She was assertive in keeping all of the workers on track with the budget and timeline, which we appreciated.  She kept us informed at every stage and gave us options that we could select from for almost all of the features in our home.  We felt that while our personal taste was reflected in each aspect of the design, she was able to refine it and assure cohesiveness.

She is an amazing designer with a great personality!  We are very lucky to have found her.  We are thrilled with the results and finally feel at home in our house.   Our daughters adore her and are still asking about her.  We have recommended her design services to family and friends.

I wanted a modern look with a warm homey feel that was also very kid-friendly. There hasn’t been one person who has stepped foot in my home who hasn’t been amazed at the work she did.”

“Being an extremely particular person who loves design, I wasn’t too sure if I really needed or wanted to work with an interior designer.  Most interior designers tend to a fit a certain mold (the stuffy mold).  Mackenzie to me is fresh, a gem in AZ.  The caliber of her design suits San Francisco, New York, LA…all the big cities.  Lucky for me, I was able to snag her in Gilbert, AZ. After meeting with Mackenzie for a consultation, I realized how helpful she would be in renovating my home.  She offered so many great ideas and input on paint,  lighting, size of furniture, contacts with tradespeople..etc. Mackenzie is super accessible, creative beyond belief, conscious of your budget, and just a wonderfully kind and creative individual.  She works with your style and does not impose her taste on you.  If you are looking for an interior designer who has an amazing eye, fun to work with, and someone who will work tirelessly and passionately on your home, Mackenzie is definitely your designer.”
