Phoenix Interior Designer Mackenzie Collier

Mackenzie Collier


Prior to graduating with honors from the Interior Design program at Harrington College of Design in downtown Chicago, Mackenzie earned her BS in Psychology from Michigan State University, where she focused on child and family psychology. The marriage of these educational backgrounds gives her the uniquely adept ability to communicate with clients and interpret their specific needs, and to understand the distinct ways individuals use their various spaces. Throughout her career, she has honed her skills in space planning and project management with a multitude of residential and large-scale commercial projects. Mackenzie constantly searches for new inspiration through travel, art, music, and nature. She loves highly functional spaces that have clean, smooth lines and light pouring in, and she is a firm believer that the best design solutions are also the simplest. 

Interior Designer Aleah Carr

Aleah Carr

Interior Designer, Project Manager

Specializing in AutoCAD and SketchUp, Aleah brings a unique, tech-savvy form of concept development to the team, along with a creativity and originality that is all her own. Born and raised in El Paso, Texas, Aleah relocated to Phoenix to attend Arizona State University, where she earned a bachelor's degree in Interior Design. She joined the MCI team as an intern and has been bringing fun, funky elements to the table ever since. Throughout the years, Aleah has worked her way to the top of the ranks as Interior Designer and Project Manager, serving as the primary contact for clients and contractors and overseeing project details from start to finish. Outside the office, if she’s not stuck with her nose in a book, you can find her curating her collection of indoor plants or hanging out downtown.

Marketing Director Jessie Wickersham

Jessie Wickersham

Marketing Director

Resident wordsmith Jessie got her start in marketing in the Sunshine State, where she earned a BA in Creative Writing from the University of Central Florida and spent time hanging out with astronauts. Prior to moving to downtown Phoenix in 2015, Jessie spent three years in Virginia’s Shenandoah Valley before packing her things and heading across the country to spend a month in the High Sierra backpacking the John Muir Trail. On weekends, she’s either hiking with friends, playing music for her dog Partner, or speaking in an old-timey voice for no particular reason.


Jillian Newman

Business Development

Give us a call, and chances are it's Jillian's voice you'll hear on the other end of the phone! A native Phoenician, Jill earned her BIS in Psychology and Marketing from ASU. Following a stint in advertising, Jillian decided to pursue another passion: embarking down the path of Sommelier. She worked in wine shops and fine dining for over a decade, and it was while running a bar in the Roosevelt Arts District that Jill became well acquainted with the vibrant arts and design scene in Phoenix. Eventually, she returned to sales and marketing with none other than the MCI crew (yay!). Outside of the office, Jillian can be found on the sand volleyball courts, sipping wine, or cooking a mean meal. 

Vern the Design Dog

And Vern, the wonder dog.

Regional Head of Security

Vern has been our head of regional security for over a decade. His encouragement and positive morale are essential to our daily office operations. He puts in long hours snoozing on his dog bed and making sure all team members get a quality dog petting session in each day. Beyond that, he even cleans our empty yogurt cups, greets our visitors, and offers his input on many complex design decisions. He invites you to come by our office and say hello!
